What Is Hiking Underwear for Women?

Hiking underwear for women is simply underwear that has been specially developed for females and hikers

Most new hikers make the mistake of packing normal underwear when going hiking.

Normal underwear for day-to-day use may not see as much movement or sweat, hence they might take longer to dry when damp, and even cause chafing when worn for extended periods, among other issues. 

Hiking underwear is best differentiated by its ability to meet important hiking needs, such as being: 

  • Quick-drying
  • Moisture-wicking
  • Breathable
  • Lightweight
  • Anti-microbial 
  • Anti-chafing 
  • Temperature-regulating 

Benefits Of Hiking Underwear for Women

Being comfortable with what you’re wearing inside is the bare minimum. Your underwear is the first piece of clothing you put on and forms a layer of protection between your privates and your hiking pants. 

Your underwear’s material and fit can directly affect your vaginal health

Wearing the right hiking underwear ensures that you reduce the chance of vaginal and urinary tract infections, and stay comfortable overall.

I mean, no one likes to sit in damp underwear, right?

Types of Hiking Underwear for Women

Hiking underwear for women come in as many varieties as regular underwear, with different cuts and colours catering to different individuals. 

But one thing that differentiates hiking underwear is the material it is made of. Hiking underwear is mainly divided into merino wool and synthetics, such as polyester and nylon.  

1. Merino Wool Underwear 

If you have the budget for it and no skin sensitivities, then merino wool underwear is arguably the best type to bring along for your hikes. Hikers love merino wool or their gear, and unsurprisingly, this association also extends to underwear choices. 

Merino wool is known for being soft, moisture-wicking, and naturally odour-resistant. 

Even though wool gets a bad reputation for being itchy, merino wool is soft and doesn’t itch. 

It is also well-loved by hikers for providing good insulation and being odour-free even when it gets damp. 

Don’t believe us? Just ask the thirteen women who wore a merino wool dress for a hundred days in a row. One even chose not to wash the dress at all and lived to tell the tale. 

We’re not saying merino’s perfect – no piece of clothing is. But it does its job well enough on hikes and despite the higher price point, it definitely delivers on value.

2. Synthetic Blend Underwear

This is more common due to it being more budget-friendly, fast-drying, and simply more widely available. If you’ve purchased athletic or sports underwear before, chances are you were wearing synthetic blend underwear. 

The active folk love it for being lightweight, but the downside, however, is that it can trap odour if you don’t change out of it within a day, or wash it. 

Realistically, most seasoned hikers would probably have and bring a good mix of both types on an extended hike. 

Most brands recognise this and use a blend of merino wool with nylon so you get the best of both worlds – the benefits of merino wool but also the comfort, fit, and durability of synthetics. 

What To Look Out For When Buying Hiking Underwear 

Now that you know what good hiking underwear should comprise of and the benefits of wearing good hiking underwear, here are some factors to consider when deciding which type of hiking underwear to get, and how many:

  • Length of the hike If your trip is short, you’re unlikely to want to waste time washing, so merino wool would be good to keep odour away. 
  • Access to laundry or washing facilities – This could be in the form of a washing machine at a rest station or even a sink where you can hand wash your underwear. 
  • Time spent in camp – This would affect the amount of time you have to dry your washed underwear. If you’re changing base every evening then you’ll need to factor more underwear than its ability to be quick-drying. 
  • Space in your backpack – Merino wool underwear can take up a bit more space than synthetic underwear, but its ability to resist odour might also mean you can maximise the use of a merino wool pair more. 
  • Weather – Remember to factor in both temperatures and conditions during the hike, and at the summit, or where you’ll make camp. 

Ultimately, underwear is a very personal choice. Despite the benefits that different types of hiking underwear deliver, you’ll still need to see what works best for the conditions around you, and your own body and skin. 

Regardless of your underwear choice, one key tip is to always test your new hiking underwear back at home first.

Wear it at home, out to the mall, for extended periods before going on your trip – see how you feel when you wear it. If you don’t like how it feels when you’re out on a short walk, we’re pretty sure that opinion wouldn’t change when you’re up in the mountains. 


How Much Underwear Should You Pack For A Hike?

Most people would pack the same amount of underwear as the number of days the trip is for, with one to two extra pairs just in case. 

This is a good gauge if you’re going for a short trip and you don’t have access to laundry facilities or time to do your own washing. 

But if you’re going on a longer hike, spanning a few days to weeks, space is likely to be a premium in your backpack. 

If you’re looking to cut down on the number of women’s underwear for hiking, then a good gauge would be to half that amount.

Say you are going for a week-long hike, you’d want to pack four pieces of underwear at least. 

My travelling rule of thumb is that you should never bring any less than three extra pieces of underwear, in case they take longer to dry or you end up needing more than one in a day for whatever reasons. 

How To Deal With Dirty Underwear On A Hike?

The first option would be to chuck it into an:

My preference is an airtight clothing bag because this means that you don’t need to deal with any odour potentially permeating the rest of the clothes in your backpack. 

Storing soiled or dirty underwear in your backpack is a good approach if you have extra space in your backpack, are on a short hike, and don’t want to bother with laundry or washing during the hike itself. 

But, if you’re going for a longer hike, then you may need to wash your underwear while out in the wild. 

To do so you can just repurpose an airtight clothing bag (ideally a mid to large-sized one) to use as a washing ‘pail’ and use biodegradable detergent to clean it. Warm water is best if you have access to it. 

If you must wash your underwear in water sources such as rivers, streams, and lakes, make sure you use an eco-friendly detergent

What To Do If You Run Out Of Clean Underwear While Hiking

We get it – sometimes it just happens.

Don’t beat yourself up over this. And most importantly: Do. Not. Go. Commando. Not unless you have an anti-chafing stick or balm that you can use to keep chafing away. 

If you don’t have time to wash or dry your underwear, I’ve found that hanging my damp towel off the top buckle of my bag helps it dry while I hike, so underwear could dry the same way. 

Sure you might get some weird stares from your hiking mates, but that beats damp, dirty underwear any day. 

Or if all else fails, you could try the age-old method of turning your current underwear inside out till you get the time to wash and dry it.

 We don’t recommend this because it may cause an infection, but hey, desperate times call for desperate measures. 

So, use these as stopgap measures if you truly must but unless you’ve brought more than enough underwear, washing should be on your to-dos once you set up camp. 


Your underwear is a seemingly innocuous piece of clothing as part of your entire hiking gear ensemble. 

But a good thong could seriously make or break your day, or even your whole hike. 

With this newfound knowledge, you have little to no excuse now for packing normal underwear for your hikes moving forward. You’ll want to make sure you have the best thongs for hiking for your next hike, no excuses.
