The Good

  • Made from soft, natural merino wool sourced from approved farms
  • Naturally odour-resistant
  • Super comfy cut for unlimited stretch and movement

The Bad

  • Merino wool tends to be slightly less durable, so it might be worth getting a few pairs to last you

Material - Merino

Cut - hipster

Colours available - Purple, Black

Best for odour control

Montane Dart Briefs

Montane's Apex D-Fuse with POLYGIENE® is a game changer. It features in lots of their other base layers too, not just underwear. It has a dual layer construction, featuring a super soft sweat-proof knit next to the skin, and a smooth face. The POLYGIENE® aspect wicks sweat and provides permanent odour control. This is a piece of underwear that takes care of itself and makes you forget you're even wearing any. Perfect, right?

The best hiking underwear should tick all the boxes, and we think the Ex Officio does a good job of that. If you're the type of person that really wants to feel good in their underwear, these are the ones for you. Style meets function with this pair, with striped mesh side panels that increase breathability and look great. They also feature antimicrobial treatment to keep you fresher for longer, especially in warm weather. What's more, the seams have been bonded to create a seam-free look, which not only looks great under leggings, but feels awesome too. They'll fit snug with the added spandex and hold their shape over time too, so worth spending a little extra. The Ex Officio Give n Go sport mesh bikini brief is also a great option.

Moisture-wicking HeiQ technology fabric with Fresh Tech keeps odours at bay and adjusts to your body temperature Bonded seams for a VPL-free look.

These could be your ideal partner for that backpacking trip!

What To Consider When Looking For The Best Hiking Underwear for Women

You wouldn't think it, but there's a lot to consider when it comes to women's hiking underwear. Here's a quick rundown on what we think is most important to consider on your hunt for the best hiking underwear for your hiking adventures.

Material - is merino wool really the best?

You've probably never given a lot of thought to what material your hiking underwear is made of, but you probably have noticed that certain clothes don't fare well in bad weather. Cotton is a prime example. It absorbs water very easily, meaning it gets heavy and takes forever to dry, none of which is ideal if you're sweating it up the hills. The mark of good hiking underwear for women should be that you can't even feel you're wearing it. It should be made from soft fabric, comfortable, light, breathable, moisture wicking and non-toxic to your body.

So, what's the best material for the job? Well, merino wool is definitely up there. Don't worry, we're not talking chunky knit wool, merino wool if you're not familiar already is a natural wool fibre that is super thin and soft, and it feels like a slightly silkier and lighter version of cotton. Its insulating fibres help to regulate body temperature, wick moisture away from the skin and minimise odour. Isn't nature great?!

Since we're waxing lyrical anyway, it's worth knowing that merino wool is also biodegradable, fire-resistant and completely non-toxic. Sadly however, being natural, merino wool isn't known for being the most durable. It can wear down fairly quickly with abrasion and is more expensive, so you'll probably be buying for slightly more, and slightly more often with this option.

Some companies have dedicated themselves to using equally efficient synthetic materials, such as polyester, nylon and spandex. These tend to be super fast-drying, stretchy, less expensive and very durable, all of which are things you should be looking for when buying your best hiking underwear yet. However, synthetic underwear tends to hold onto odours instead of fighting them, so they can get stinky pretty quickly. They're also industrially produced using non-renewable energy from fossil fuels which doesn't sit well with everyone (including us), but they are cheaper and more readily available.

Cut

Only you know which fit works best for you so this isn't really something we can advise on too much, the bottom line is whatever you feel most comfortable in, wear that. Whether that's hipster briefs, bikini, boy shorts or thong style, we're all different and we've tried to include a range. Most of the hiking underwear we've listed however are available in different styles too.

Seams and Stitching

There are two reasons this is important: comfort and style. I mentioned before that the best hiking underwear will be so comfortable you won't even be able to feel you're wearing it. Quite often us women will wear leggings or tighter fitting trousers and shorts to hike in, and nobody feels great with a VPL (Visible Panty Line). Undies with flat lock stitching or no seams at all will be your best bet. You won't be able to feel you're wearing them and best of all, they won't be visible!

Washing Care for Hiking Underwear

If considering the wash care of your new hiking underwear doesn't fall into the category of self-care we discussed at the start, I don't know what does. Merino wool, for example, should be washed on a lower heat with less spin to avoid shrinkage, and shouldn't go in the tumble dryer as the heat tends to wear the fibre out. If you're worried about ruining your new merino underwear, you can always hand wash it.

For some, that is simply too much thought to have to put into washing underwear. Synthetics are generally safer to just chuck in with the rest of your clothes, so it's worth considering before you buy.

FAQ

Look, we're not here to tell anyone what to do or what not to do, it's your life. But we do challenge you to go hiking for the day in normal cotton underwear and tell us you weren't uncomfortable, sweaty and sticky at any one point.

You can go hiking in jeans and a fur coat for all we like, all outdoor hiking clothing does is make you last for longer on the hills and it's generally more durable too.

Women's hiking underwear that's soft, comfortable and moisture wicking will be a far better bet than those grey cotton undies with the dodgy elastic you got for Christmas five years back.

Material is a good place to start. Fabrics like those from merino sheep are natural and don't produce nasty emissions as some synthetic materials do. Plus, wool is naturally odour resistant, it's quick drying and it'll keep you cool for long days on the trail.

Some companies such as Patagonia also use synthetic recycled materials, such as nylon, which is heaps better for the environment too.

Generally we'd recommend opting for what you usually wear and what you're used to. The best women's underwear for one woman won't necessarily be the same for you, so decide what's most important and go with that.

When it comes to washing hiking gear, you do have to be a little careful. Fabrics like merino wool are susceptible to shrinkage if you wash them too high. Synthetic materials, such as nylon and polyester, can generally be chucked in with the rest of your clothes. Just make sure you check the wash label first.

Avoid using detergents as these can destroy the moisture wicking properties of walking gear.

Odour resistance, moisture-wicking properties, sustainable construction and durability are our top things to look for. Comfort is also key. Hiking underwear for women is very varied in terms of cut, style, coverage and price, so go with what you feel great in.

Conclusion

The best underwear for you will be largely dependent on what activities you'll be wearing them for, which cut feels more comfy for you, and your budget.

If you're watching the pennies you can't go wrong with the Decathlon Merino. If you're tackling a multi-day backpacking trip you'll appreciate the odour control and moisture wicking skills of the Montane Dart Briefs (these guys know all about bringing the heat!) and if you want something that looks great but still does the job, there's the Ex Officio.
