Sure, some polyester underwear wicks, but the polyester also retains odor—sometimes even after you wash it. The Icebreaker Women’s Nature Hot Pant Underwear naturally manges moisture and block odors. Since feeling sexy often starts with your undies, Icebreaker made the Nature Hot Pants with a low cut in front and back. The ultralight merino wool fabric feels smooth and soft, and side paneling matches some of Icebreaker’s tanks (sold separately).

Pretty great!

I enjoy the fit of these, but they aren't as flattering on me as the I/O boy briefs. Still good tho!

Never thought I'd spend this much on panties but I'm glad I did

This was a stretch for me, but I read reviews and thought "what the heck".

I needed good underwear for hiking Mt. Whitney last month. And these were great - felt fresh and clean the 22 hours of hiking I did that day!

Now that I'm off the mountain, they are my favorite panties to sleep in, too. (I don't wear pajamas).

I highly recommend them.

Great fit - doesn't ride up

These are my new 2nd favorite pair of underwear (after IceBreaker bikinis). They stay put and are plenty soft, especially after a wash with Kookaburra wool wash. Even on the small size, the leg openings are big enough for my pillar biking thighs.

worth a try

i agree with sizing variations: an xs seems to fit me in these, whereas in the icebreaker siren i got a small. I don't adore the elastic on the bottoms and i think they might be uncomfortable or rub during use, but I'm going to give them a try as they've gotten such great reviews.

My favorite icebreaker undies. I like the fit better than the hipster since it covers more of the rear. Also, icebreaker really does retain warm even when wet ... unintentionally got my lower half wet at the beach in cotton shorts, my legs thighs were freezing but my butt was warm!

I would order one size smaller

These just arrived today. I wanted to say I agree with the need to go a size smaller. I usually get a small in underwear, and in fact sometimes go one size up, as I the Ibex boyshorts, which fits a bit better in med than small, though both are good. In these Icebreakers Hotpants, the small seems too big, like there is way too much fabric and so loose can ride up. I am going to return them. I'm not sure if I should replace them with an XS, since they don't seem very stretchy, so the XS may be too small. (The Ibex boyshorts are waaaay more stretchy.)

sizing off?

Icebreaker makes great quality clothes, however this particular cut of underwear is not consistent with their other briefs and tops ( or perhaps it was mislabeled) - the medium size fit like a large, and this is compared to the nature 150 bikini, of which I have both small and medium. I fit well into either small or medium icebreaker tops and bottoms, depending on wanting a slightly snug fit or slightly relaxed fit, so I ordered a medium in the 150 hot pant and it was too big ( felt like a large on me), so I exchanged it for something else. A small would probably have been fine, but no smalls left at the time. Anyway order a size smaller.

My Favorite Underwear!

I love these! I bought a couple different types of merino underwear to thru-hike the Appalachian Trail last year, and these were by far my favorite. Like all merino, they do tend to get holes somewhat easily, but I think this is unavoidable. They are extremely comfortable and technically great (wicking, quick-drying, etc.). I lived off only two pair at a time, washing on-trail when I was out for more than four days at a time. Each pair would last me at least three to four months like this, under extremely tough use. If I could afford to buy these for my entire "real world" wardrobe, I definitely would! One note- I agree on sizing issues. I tend to wear a medium, but a small in these fits me great.

I am typically a size small in everything. I ordered the small in these and they are absolutely enormous!

Icebreaker panties..the best

Love these panties, perfect for hiking, don't bunch up and super soft like all of my icebreaker.

Best Underwear!

One of the most comfortable pair of underwear I have ever owned. I have tried the ex-officio give-n-go hiking underwear and these are more comfortable.

Fit fine, but i think i could have done without

I got the x-small for being 5'2'' and 108 lbs. I think that the icebreakers did fit well. They do dry quick over night but one days worth is better. I found them helpful wearing them for many days with a liner and they did not build up in odor at all.

Great Fitting

The sizing chart isn't exactly true to size, but I got an XS knowing that it's the size I fit in other brand name undies at 5'2'' and 108lbs. After trying on the Icebreaker nature undies they fit perfectly. The designs are very chic and simple, which is why I think they're so attractive. I bought two colors and love them both. I do agree with some comments that they ride up the booty just a little.

Excellent Cold Weather Undergarment

Love these like I love all other Icebreaker--no itch, soft as a newborn rabbit and cozy to boot. They have a tendency to bunch up a tad especially if you are doing squatting motions a lot (like in skiing). It is a very minor problem though and these are still my go to in cold weather activities (and sometimes around the house too!)

Awesome undies

I really like these underwear. No itching whatsoever, and they did not ride up at all. True to size for me. I'm a medium and they fit great. Not sexy, but not old-lady like either. I may have to get more...

Soft and cute

They look good and are very soft. Not itching. I wore them hiking and climbing and they did not ride up. The size is on the large side (I usually wear XS but wish there is XXS) and the rise is a big too high for me, although it does help keep my lower back dry.

Yay! Warm!

It's freezing out here. I'm so glad to have these. Don't expect them to fit like bikini or even hipsters. They are *supposed* to go down your leg a bit, they're hot pants. I think they're pretty true to measurements -- I take XL in everything else Icebreaker, but my hips are proportionately smaller than my waist, so I take a L in these and could probably go with a M safely. Because I'm not what you'd call svelte, they're not the most flattering undies I've ever worn (they dip down a bit too far in front for my tummy pooch to be anything but obvious), but they're warm and they're comfy. Which was why I got them in the first place! If I want to feel a bit more stylish in the undies dept., I wear the hipsters.

I think the Nov 9 reviewer was way too harsh on these undies.. I ordered my normal size and they fit great. Design on the side is cute. Only complaint is that I don't love the backside view of the hot pant on me cuz they look more like regular undies (but that could just be my backside's fault lol). These are great under ski pants and jeans in the winter.

no diaper

I disagree with the diaper comment. They fit me perfect, don't ride up and stay in place.

Responded on

Agree! Diaper not. Very low rise, snug and CUTE! Love 'em. 5'5" 112 lbs XS

feels like a diaper

do you like diapers? if u do this is it for you! if not dont bother, they ride up they bunch up, they feel like 4 x the right amount of cloth needed was taken to produce them. have a nice day.

Responded on

I thought the fit was great. Seems true to size to me.
The bonus is that they don't get clammy when wet or sweaty, nor do they get stinky like my polyester underwear.

Responded on

OP must be referring to a different product. 5'5", 112lb. XS -- snug and ride low -- Hit maybe 5" below belly button and barely cover crack in back. Lightweight, fast drying. Cute and awesome. Also, check out the Stoic boy shorts -- little more coverage but still low rise and cute. (Only two boy shorts I have ever liked.)
