How to Choose the Best Women’s Hiking Underwear
But how do you choose the best hiking underwear for you? Underwear is not a returnable item, so you can’t try them on and then return them. And with every panty that doesn’t do what it’s supposed to do, there goes a few more dollars down the drain.
So let’s look at factors involved in picking the best women’s underwear for hiking to prevent chafing and the perfect sweat absorbing underwear. It doesn’t really matter if you are just out for a day hike or looking for the best women’s backpacking underwear for a long trip, these are the critical features.
Moisture Wicking is a term women’s hiking underwear manufacturers throw around but what does it really mean? It means the material absorbs moisture from the skin surface. The moisture then evaporates from the surface. So really, a good wicking fabric isn’t really sweat proof underwear. What it does instead is become a sweat absorbing underwear.
Fabrics, like merino wool, that can hold a high ratio of moisture are considered the best moisture wicking underwear.
Unless you’re hiking in the middle of the desert, you’re likely to encounter rain and streams on your hiking or camping trip. Lightweight and quick drying are important to stay comfortable and eliminate rubbing and chaffing.
Bikini area sweat is real! Undies that have antimicrobial properties reduce body odor, keep the undies fresh longer, and can be worn for days together. Synthetics like polyester and nylon are usually treated with antimicrobial chemicals so that they stay fresh longer, while bamboo, merino wool and hemp have natural antimicrobial properties.
It’s always safest to stick to the style of underwear you wear regularly. Then you won’t be tugging and pulling on them all day when the ride is unusual. In general there is a large select of briefs, bikinis, boy shorts, thongs and hipsters that feel comfortable and flexible. Many ask if thongs good for hiking? In some cases, yes. Thongs designed for athletic wear are very different from those for sex appeal, cut specifically so they don’t shift and rub as you move.
There are no washing machines on the road. So if you’re traveling for days, you might not have the luxury of washing your panties for a few days. When you’re hand-washing, you’ll really want quick dry underwear or fast drying underwear.
But if you want the best quick dry travel underwear, merino it is. Synthetic dries pretty quick too. You cannot lug around a dryer on a trek. So drying your panties on a rock or string for a few hours may be your only option. So yes, if you’re looking for quick dry, merino is the best. If you’ll have a few hours of leisure time, polyester or nylon is great too.
Comfortable Seams and Stitching
Some undies have seams running down the center of your bottom or in the front, while some have seams running across them. Those may be okay for regular days, but when it comes to hiking, they’re an absolute no-no and can cause unnecessary chafing. Undies with flatlock seams or no seams are the best option for hiking underwear.
Also look for waistbands that don’t dig into your skin. A wide no-roll band or even some with no waist band are much more comfortable. And don’t forget that tag that rubs the small of your back all day. Look for tag-less or panties that have an easy to remove tag.
REVIEWS of the BEST HIKING UNDERWEAR for WOMEN
Best Merino Wool Women’s Underwear
Merino wool is without a doubt the most natural way to find comfort when hiking. The natural moisture wicking and fast drying properties can’t be topped. The wool from these unusual sheep creates the strongest and softest wool fabric that is perfect to wear against your skin. Here’s our favorite choices for merino wool hiking underwear. The two biggest brands for merino wool hiking clothes are IceBreaker and SmartWool, both with an excellent selection that we cover below. We’ve also included Woolly Clothing because it offers a more affordable alternative to the other 2 brands.
ODOR CONTROL: 🧡🧡🧡🧡🧡
COLORS: Heather, Black, Pink
STYLES: Bikini, Hipkini, Thong
SIZES: XS to XL
Our top pick for hiking underwear is the IceBreaker Siren Series. Primarily made of merino wool, you get all the amazing benefits of that fabric like the best moisture wicking, quick drying and odor control. The core-spun fibers, (which means the wool is wrapped around nylon), provide strength and structure to these panties while you only feel the softness of the merino wool against your skin. The tiny bit of lycra gives these hiking underwear a bit of stretch that makes the IceBreaker undies a step above the others for retaining shape and stretching as you move.
PROS: With all the benefits of odor control and moisture wicking of merino wool, these are really comfortable panties. The low profile elastic waist and leg openings keep these from rubbing when you get sweaty.
ODOR CONTROL: 🧡🧡🧡🧡🧡
COLORS: Black and Gray
STYLES: Bikini, Hipster, Thong
SIZES: XSm, Sm, Med, Lg, XLg
The SmartWool Merino 150 series wraps the fine fibers of merino wool around a nylon core. That means the soft wicking wool is all that is touching your skin. While the nylon core allows the fabric to flex with your movements. These SmartWool underwear are designed for non stop comfort when hiking with a soft elastic waistband that won’t chafe. The fabric is SmartWool’s lightest jersey blend so these hiking panties will feel like they are barely there.
Merino underwear can be quite on the pricy side. However, Wooly Clothing has successfully designed moderately priced panties for the modern hiker. You’ll love the smooth flatlock seams and soft wrapped waistband that will eliminate chaffing. And you’ll appreciate the super soft fabric that quickly wicks away sweat while hiking.
PROS: More affordable merino wool option. Will keep you super dry and comfy.
CONS: Lack of styles for people who like more traditional briefs.
Best Bamboo Women’s Panties
You may find it hard to choose between bamboo and merino wool for hiking underwear. For me, the Boody Body EcoWear is our number 3 choice for amazing underwear. The decision line is pretty thin. The merino wool from SmartWool and IceBreaker feels a little softer while the Boody panties have a bit more structure. As far as keeping cool and dry I’m in love with all 3.
ODOR CONTROL: 🧡🧡🧡🧡🧡
COLORS: Black, Beige, Nude, White
STYLES: Classic Bikini, G-String, Bikini Brief, Mid Brief and BoyLeg Brief
SIZES: Sm, Med, Lg, XLg
Available in 5 Styles: Classic Bikini, G-String, Bikini Brief, Mid Brief and BoyLeg Brief! Check them all out here.
Everything about the design of Boody Body Ecowear screams comfort. You can start with the unique manufacturing process that eliminates pesky, rubbing side seams. And the wide no roll waistband is super comfortable. And most important they will keep you fresh and dry on the hottest hikes. If you are looking for something comfy, feminine and practical this an excellent choice. Boody’s committed to providing ethically made under-garments made from sustainably sourced bamboo.
PROS: Wide variety of attractive, feminine styles that work for everyday as well as long hikes! No rubbing and chaffing. High moisture wicking and drying ratios.
CONS: Although a little pricier than the average undie, they’re not crazy high.
ODOR CONTROL: 🧡🧡🧡🧡🧡
COLORS: Black, gray, purple, skin, rouge, white
SIZES: US Sizes 4 through 10
You’ll love the wide waistband in Warm Sun’s Women’s Bamboo Panties that will reduce chaffing and rolling on a long hike. They are super soft to the touch and incredibly lightweight. It’s hard to believe that they work so well at wicking moisture away from your skin. The little bit of spandex woven into the bamboo helps the fabric hold shape and stretch with your movements.
PROS: Very affordable. Extremely lightweight and soft. High moisture wicking and drying ratios. Large selection of sizes.
CONS: Only available in briefs, this is a lighter weight fabric than the Boody which stretches after washing so order a size smaller.
Best Hemp Hiking Panties for Women
I’m new to hemp fabrics in underwear so still a bit undecided on the future of these panties in my hiking wardrobe. However my initial tests are very promising. They stayed super dry and comfy on a really hot day. So I did a lot of extra research into hemp fabrics in general before adding to this list. I definitely think you’ll appreciate the natural qualities of hemp.
ODOR CONTROL: 🧡🧡🧡🧡🧡
COLORS: Black, Green, Beige, Nude
STYLES: Hipster, Bikini, Thong, Boy Shorts and Hi-Waisted
SIZES: US Women’s XS to 3XL
The comfort in the WAMA Ladies Hemp Underwear starts with the soft flexible waistband with a flatlock seam to avoid rubbing as you hike. You’ll appreciate the moderate 2 way stretch in the fabric which moves with you while still holding their shape wear after wear. We thought the fabric in these panties felt similar to cotton, but love the breathability that the hemp weave brings to the fabric. You will stay dry and cool with these.
PROS: The design of the waistband is likely the most comfortable of any of the panties we reviewed. It’s soft and stretch and won’t rub during the heat of the day.
CONS: You will need to wash these a couple times to get a softer feel, right out of the package Hemp Panties feel a little stiff.
Best Synthetic Blend Women’s Hiking Underwear
After all those great natural fiber choices, why would anyone look at the synthetic blends? Well, there’s 2 very good reasons. The first is that underwear made of synthetic blends is a little bit less expensive. The second is that they have almost zero special care requirements. If you are a gal who dumps all your laundry in one load and never has time to separate your delicates then these panties are going to survive. To be fair, both my bamboo and my merino wool undies have gone through normal wash and dry cycles without a hitch but I suspect, based on experience, that if that happened frequently they would fail me fairly quickly.
ODOR CONTROL: 🧡🧡🧡🧡
COLORS: Assorted colors available
STYLES: Brief, Hipster and Bikini
SIZES: US Women’s XS to XL
ExOfficio’s Give-N-Go Underwear has long been a favorite among hiking women. However the release of the 2.0 version really took the quality and appeal up a notch. They start with a breathable mesh fabric to allow air flow that will keep you cool on the sweatiest days. The blend of nylon and elastane gives the fabric a lot of stretch for extra comfort. And the fabric is treated with with an antimicrobial to keep away odor.
PROS: We love the super lightweight fabric, it will feel like you are wearing nothing at all. These panties feature a comfortable wide waistband and flatlock seams to eliminate rubbing and chaffing during an active day.
CONS: Seriously our first choice for hiking underwear if you want to get away from natural fabrics. You many find the texture of the fabric a little unusual due to the open weave that allows the fabric to breath, but most wearers love these after giving it a try.
ODOR CONTROL: 🧡🧡🧡🧡
COLORS: Black, Beige, Tan, Blue
STYLES: Brief, Hipster, Thong and Bikini
SIZES: XS to XL
REI Co-ops Active Women’s Underwear is made from a stretchy polyester mesh. As a result they are extremely lightweight, designed to breath which means it will keep you dry when you are hiking. The antimicrobial treatment reduces any odors from sweaty days.
PROS: We love the lightweight seams, especially that there are no side seams to reduce chaffing when hiking. As you can imagine, seams rubbing seams as you often have between your pants and your undies can create a lot of friction. This design eliminates that double seam rub that we all hate.
CONS: With heavy wear, these might not feel like they have enough structure for many hikers who want something that withstands pretty much any harsh climate because they are intended to be lightweight panties.
Best Cotton Blend Wicking Women’s Panties
To be clear, cotton is not our top choice in hiking underwear. No matter how it is woven, it is going to dry slower than any fabric. However I know many of you have sensitivities that require cotton against your privates. So if cotton is your go to, then these are great choices specifically woven to keep the active women as dry as possible.
ODOR CONTROL: 🧡🧡🧡
COLORS: Assorted multi package
STYLES: Brief, Hipster, Bikini and Hi-Cut
SIZES: US Women’s 5-9
So what makes these different than regular cotton panties? Well Hanes calls it their X-Temp Technology which is a hydro-funtional polymer designed to wick moisture away. I know that sounds a bit high highfalutin technology, but what I get from it is they’ve done something with how they weave the fabrics to improve the moisture wicking, hence keeping you cooler an drier. What you will like about the Hanes Constant Comfort X-Temp Panty is the wide smooth waistband that will not roll when you are in motion. The fabric is soft and comfy.
PROS: These are so cheap compared to other quick drying panty options, generally just a couple bucks a pair. If money is no concern, pop up top for the bamboo or merino wool options. But sometimes when you are traveling having some inexpensive undies is exactly what you need.
What Materials are Best for Women’s Hiking Underwear
The best hiking and athletic underwear are generally made of bamboo or merino wool. However there are a lot of fabric blends that provide comfort when you are hot and sweaty. Let’s take a closer look at each type of fabric so you can decide what’s best for your undies.
Is Merino Wool Good for Underwear?
Once considered a fabric only fit for kings, today’s hikers sing the praises of Merino Wool Underwear. It’s the perfect fabric for hiking underwear because it will keep you cool and dry longer than any other fabric.
It’s really, really soft! The wool of the merino sheep is extremely strong, long and fine. When spun it becomes one of the softest finest threads and weaves into a premium fiber you would never ever expect from wool. Merino wool is not your mama’s wool, all itchy and scratchy. Merino wool has a high moisture absorption ratio so it pulls water away from your skin making it the best women’s underwear for hiking. And then it breathes, allowing moisture to escape to the surface and dry quickly. Super comfortable on the hottest days! Most people who have wool allergies have no problem with merino wool because of the difference in the fiber structure.
You can wash your merino wool underwear with your regular wash in cool water, but it is better to line dry them to maintain the life of the material. The good news is they dry quickly. So when traveling or backpacking, you can easily hand wash before bed and find dry fresh panties in the morning.
Merino wool also is perfect for base layer long underwear for winter hiking for all the same reasons! The only downside to merino wool is the price. Quality women’s merino wool hiking underwear will generally run $30-$40 per pair.
Is Bamboo Underwear Good for Hiking
When bamboo fibers are blended with stretchy fibers like spandex, you get a fabric that is perfect for hiking underwear.
You may have never considered Bamboo as a source of fabric, let alone underwear. But seriously, it is a pretty amazing choice for the best backpacking underwear. First it’s super soft, almost silk like. The yarn that is spun from bamboo has smooth round edges which means when you run your finger over the fabric, it just rolls over.
You’ll love that bamboo naturally stops odor-producing bacteria from growing and spreading in the fabric. As a result your underwear will smell cleaner and fresher.
Most people with skin allergies, find bamboo the perfect fabric. Caution though, all bamboo fabric is not made the same. Some of the older processes for altering bamboo stalks to fabric used caustic chemicals. Make sure you select a bamboo panty that is using a non-toxic solution in the soaking step.
You’ll feel nice and dry due to the natural absorbing properties of bamboo. This fabric creates amazing moisture wicking underwear. The fabric also dries quickly so you will feel comfortable. Compare that to a fabric like cotton that also absorbs easily, but doesn’t dry quickly and you feel the wet fabric against your skin all day.
Bamboo fabric can be machine washed and dried at cooler temps. (Although I often forget my bamboo is in the laundry and haven’t noticed any shrinkage.) That’s because fabrics that have small amounts of synthetics, like polyester, blended with bamboo seem to have less shrinking problems.
Hemp in Hiking Underwear
Hemp has been emerging in the marketplace as an all natural source of fabrics. The high tensile strength of the hemp fibers result in a very durable fabric. Ecologically hemp production generally has a positive impact on the environment. It doesn’t require much water, grows fast, returns oxygen to the environment at a higher rate than trees and can be easily grown without herbicides.
Does hemp fabric work well for underwear? Sure we all care about the environment, but when it comes to our best hiking panties we need the fabric to do a whole lot more. First hemp naturally has a high anti-bacterial property that will keep away the stink and makes it attractive for hiking clothes. It will wick away moisture and dry fairly quickly. Because hemp is usually blended with cotton to add softness it may not wick as well as 100% merino wool. We all know that cotton likes to hold moisture, but as long as the blend is close to 1/2 hemp you will experience a very comfortable breathable fabric that works well for hiking.
The downside to hemp fabric is that it feels a little stiff when new. It will take several washings to soften the fabric. Just as in any natural fabric you should wash in cold water and air dry.
Anti-Microbial Synthetic Fabrics
I have mixed thoughts about hiking panties made from Anti-Microbial Synthetic fabrics. First synthetic fabrics are usually very reasonably priced compared to the all natural fabrics. Synthetics also are amazingly durable, putting up with almost anything we can do to try to destroy them like leaving in a hot dryer or snagging in our backpack. Synthetics like nylon and polyester are perfect for women’s hiking shorts because they are so durable. They will hold their shape and endure. I don’t know about you, but I definitely need the lowest maintenance clothing possible!
On the down side, synthetic fabrics are not naturally good at wicking away sweat and lack antimicrobial properties. That means untreated they will be damp and stinky pretty fast. However major brands overcome this concern by designing the best women’s hiking underwear with venting so it breaths and treating the fabric to make it antimicrobial. Sportswear that is anti-microbial treated generally are either surface treated or have tiny bits of silver (or other metals) woven into the fabric. The silver releases ions that keep bacterial and fungi from growing.
So is cost and durability are your top concerns when selecting women’s hiking underwear, then synthetic fabrics will be at the top of your list. We’ve selected several top rated panties to share with you.
Cotton Blends Might be Back in The Game
Cotton is generally a no, no for hiking underwear. While it has an extremely high absorption rate, cotton likes to hold on to that water so it fails to dry quickly. That makes cotton the source of nasty chaffing when hiking. No one wants to hike all day in wet panties.
However, for some people with allergies, cotton is always their go to natural fabric. Luckily there are several cotton blends that are advertised as quick drying and cooling. Surprisingly I found an amazing choice in the Hanes Women’s Constant Comfort X-Temp Panty These panties are also the lowest cost solution. However, that said, my first choice for women’s hiking underwear will always be either merino wool or bamboo.
What are the 🧡🧡🧡🧡🧡 Ratings in our Reviews?
The heart ratings for each item are based on several factors. First is our own personal experience. We’ve been hiking and camping for years and are definitely opinionated about what we like and don’t like. And we don’t like things that are of poor quality or don’t do the job as described. You’ll never see those items in our reviews. That means you’ll never see items with less than 3 🧡s. We also ask our family and friends who love the outdoors for their recommendations. To Brad’s embarrassment, I’ve been known to stop fellow travelers and ask their opinion about a product I see them using, hopefully not coming off as too creepy (lol). And I’m obsessed with reading all the reviews on the products we share just to make sure I didn’t miss something.
So… The Best Hiking Underwear for Women are Pretty Amazing
As you can see, natural fabrics offer a lot more than just being sweat proof underwear when it comes to keeping you dry, comfortable and odor free when hiking. What a gift on a hot sweaty hike! Without a doubt merino wool or bamboo are amazing choices for the best hiking underwear for women. Even so, it’s nice to have an affordable option for best women’s hiking underwear in the new technology synthetics and cotton blends. Sending wishes for a happy and dry hike!
