    Definitely a good buy! I ordered a medium size (weighs 115) and fits perfectly. The material dries quickly and soft to skin.

    Love merino everything, so of course I'll buy merino panties when they're on sale. They're so expensive, but worth it. Super soft, easy wash, dry fast. Great for bike touring (which is what I like to do).

    I got one pair of these underwear to try out and liked them so much bought two more. I wear them on hiking/biking trips and they dry quicker/smell better/are less irritating overall than cotton. But are super thin and comfortable (when I first thought of wool underwear it sounded like a terrible idea!). Not sure how long they will last but they are worth it as long as they do hold up.

    I admit that I am picky about underpants. I do not think I should have to pick wedgies in public. These underpants, for any woman with anything other than a flat backside, are a guaranteed wedgie machine. I typically wear cotton bikinis, and ride-up is not a problem. Pantylines are not a usual worry for me. I am currently wearing these on a long trip through Italy (able to drip dry in the worst of conditions) and cannot WAIT to rip them off once I arrive stateside. The positives are that the fabric is great and they are comfortable in the 90 or so degree heat in Rome. The problem is that they are all but unwearable because of the wedgie situation. If you see an American in Italy with a major wedgie this summer, you'll know it's me.

    Very comfortable material and fit. I have been using exofficio underwear on long (hot) hikes recently, but they somehow always trapped in sweat and odor. This product is the complete opposite- it's definitely breathable, odor resistant. It also dries quickly. I bought two more pair and have convinced friends to also invest. I cannot recommend enough!

    I agree with other reviewers that there is too little coverage in the back. I much prefer the fit of the Icebreaker hipkini, which is made of fine merino wool and doesn't ride up or show panty lines. These are going back.

    The fabric and construction of these panties is very nice, however there is just too little fabric on the backside to cover the derriere to my liking. I wear size 2 pants and size 5 in department store undies and the size small in the smartwool bikini had about half as much coverage of my backside as I would like. I don't know whether sizing up to a medium would solve the problem but might be worth a try because of the overall quality otherwise.

    They were very soft, dry and odor resistant as described. Wore during strenuous day of work and working out. Size seemed a little small for a medium. I wear size 8-10 pants and size 6-7 underwear and the M was a little small. Fit around no problem but the cut in the back was a little skimpy for me. Probably not a problem for most women. I still like them in spite of that, and would buy several more if they weren't so expensive.

    Bought these to go camping. Typically wear between a small and medium. Medium fit better.. went back and bought more.
    Light, easy to dry. Great panties for camping.

    i have owned 4 pairs of these, as i am a fiend for wool clothing. compared to Ibex's seamless wool underwear, these smartwools shredded at the seams after only a few uses. the fabric is so thin it doesn't really stay in place very well. but, as for the wool, completely itch-free, and they are cute looking. wool is great to wear if you are active . i am a professional landscaper and i feel dry and comfortable after a long day's work. wool is the BEST ! i hope smartwool keeps trying to perfect their underwear.

    I am a big SmartWool fan - I only wear their socks year-round - but this is the first time I've tried their underwear. I bought a pair to take on a week long ski trip and found it very comfortable. No itch and the fabric is is very light and sheer - takes up no space when packing! Can be hand-washed in a sink , rolled up in a towel then tossed over a shower rod and it is dry and ready to wear in the morning. Wish they had it in black; if they do offer it in the future I will be ordering. I am 5'5", 145lbs, 37-29-39 and ordered a medium and it fit perfectly.

    Pricey, but worth every cent. I have finally found a panty that is comfortable, doesn't show panty lines, and is breathable. I'm throwing all others away and investing in this essential piece.

    The usual good quality of Smartwool products, however, their sizing seems inconsistent. I can wear a small in a skirt, with even a little room to spare, but a medium in the underwear or tights barely fits me. If you are between sizes, go larger in these.

    Very thin fabric, but oh so comfortable--they don't ride up, and I don't even feel that I have them on. I usually wear size 6 in regular panty sizes and the medium in these fit like a dream. If you wear a 5 or smaller in regular panty sizes, you should probably go with a small. Highly recommend.

    I love these--they are really comfortable and sleek. The thing is, I don't wear a large in any other style of underwear. But the mediums were uncomfortably tight. So consider ordering a size up.

    This underwear is very light weight and flimsy, did not hold up well and did not fit me well. I have other wool undies that I prefer for hiking/backpacking such as the Icebreaker Siren.

    best underwear ever known to womankind. super soft, lightweight, feels like youre wearing nothing. wool, undyed so it feels even more natural and wont show under white clothes. true to size, im petite 4 and got a small, they are perfect. medium fits ok too just a little loose. high quality. at $12 a pop these are not only the best but also the best value.

    Finely constructed in merino wool, these are super comfortable. More elegant than some other merino wool alternatives, they fit well and don't have any excess bulk. Great product and a great buy if you can get them at a bit of a discount.

    So far I have purchased 6 pairs of these. They fit great and do not tend to ride up. They do not leave 'panty lines' like most and are barely noticeable. I originally purchased these for hiking and they do not cause chafing but like them so much, I wear almost daily. They are not too high cut and do not tend to show in a low to mid rise jean (I hate when my undies show!). I am approx. a size 4 womens with a good sized tush :-) and the medium fit great.

    These are as advertised - bikinis. I was hoping they would fit me more like hipsters.
    They are keepers for backpacking/hiking but not as everyday undies as I am more comfortable in the hipster style.

    These are wonderful for all that you might expect from wool underwear, comfortable, very breathable, and more odor resistant than other types of material. Be aware that they are very thin however. This makes the comfortable and light and breathable, but I expect them to last less time than my regular old cheapy cotton ones, which may be a consideration when paying this much for underwear. I plan to keep them for backpacking and longer-term trips only, versus everyday wear.

    I have another style of SmartWool underwear and it's held up very well for over a year now, so I thought I'd try these. I had to send back my first attempt because they were too small, but I ordered the next size up and they fit very nicely. I think SmartWool is so comfortable and the original pair had always become the go-to pair to grab as soon as they were through the wash, so I was happy to add another pair to the pile.

    I usually wear a size L, so I ordered my regular size and they fit small, but I thought not so small that they were unusable. So, I washed them and hang-dried, and wore them again and then decided they were definitely too small for to wear under clothing for every day activities. Not tiny around the waist, but for me the seat of them is too narrow and they tend to ride up and generally don't stay put. I have the matching cami tank top for these, and I really like the top, but these undies don't fit as well. Now I just wear them to bed, since I wear the cami to bed also, so it's a matching pair lol. The material is very soft, but thin, and the beige is somewhat see-thru.

    Also this material really takes on color from the wash. Nothing else was affected in the load I recently did except these undies, they absorbed color and now they look tye-dye, so they definitely need to be in a light-colored load! Overall I'm not happy with them, but not hating them either, just wish they fit a bit better. Price was good tho.
