    Does the job

    • Familiarity: I gave it as a gift but have feedback to share
    • Size Bought: Medium

    Gave these to a friend who is 5'1" with an athletic build. She wanted medium size and said after trying several other brands, these fit the best. The leg holes aren't as comfortable as she would like, and they create a pretty serious panty line but the performance/technical aspect outweighs the fit.

    Runs REALLY small

    • Familiarity: I returned this product before using it
    • Fit: Runs small
    • Size Bought: Medium

    The quality seems great and I will update this review when I actually get to try them for backpacking in the right size.

    My warning is that they don't just run a little small, they run REALLY small. I am 5'5" and 110# so pretty slender and petite. I usually wear a Size 5 (small) in Hanes Comfort Soft bikini underwear for every day. I sized up to a medium for these per recommendations and STILL too small for me. They are at least 2" shorter around the waistband than the Hanes. I can't believe I have to order a large in these bikini panties. That is definitely ridiculous sizing. I would say the medium is more like a standard x-small.

    Underwear nirvana...

    • Familiarity: I've put it through the wringer
    • Fit: Runs small
    • Size Bought: medium

    I own these in the medium and large in sand, black and pink. Ordered sea glass to mix it up a bit. Great for everyday use as well as hiking/backpacking. Fits perfectly with no panty lines, UNBELIEVABLY breathable, no odors (unlike synthetics, which stink, even the "travel" ones hold an odor.) They've lasted well over a year of hard use with machine washing in a laundry bag and drip drying, which takes minutes in a dry climate.

    Fit like a glove, although they do run on the small side. The only caveat (and it's a very minor one) is that they don't stick very well to pads, but they are so well cut it's not a huge issue.

    I am hoarding these in fear they will stop making them. I can't go back. Worth every penny.

    Best Women Best Women's Active Breifs

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: small

    My mom says these are the best active briefs on the market. They stay put, can be worn for multiple days backpacking, dry fast, are odorless and comfortable. Definitely worth the money.

    Finally underwear that stays put!

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: XL

    I bought these after frustration with both Smartwool and Icebreaker underwear riding up while hiking. Hiked in these on 12+ hour hiking days and they stayed where they should. The wool ventilation was great in the Costa Rican heat. I'd like to buy more, but the XL size is hard to find.

    • Size Bought: Large

    I've had these for five months now, and they still seem brand new. Super comfortable and they stay in place. More substantial material and coverage than Icebreaker or Smartwool. I'm buying more. I'm between sizes on the hip measurement, and sized up, perfect fit.

    Tied for my favorite backpacking undies

      I pretty much agree with the June 2011 review. I wore these on my Appalachian Trail thru hike for about 4-5 months or so? With intermittent washings, of course. I can't be sure if I ever messed up and put them in the dryer but they held their shape well. I'm 5'4', 130-135lbs, hippy, and usually wear a dress size 6. In my case, I wore the small and kept them even though they were a little tight. I'd have gotten the panty line effect if I had been wearing see through bottoms. But I didn't want them too big so they wouldn't ride up. I agree that the angle is a little steep, but not too steep for my body type (think Jlo...). I wore exofficio, smart wool, and icebreaker underware also, and these tied for my favorite with smart wool. The icebreaker ones I had gotten were too heavy for summer and not stretchy enough. Exofficio stank up fast. These were really up there in quality for backpacking undies. I didn't get any holes or runs in them. The only problem I had with them was staining. I got a teal blue color and stains would never come all the way out.

      Not everybody likes a hipster

        I love these undies. After auditioning many pairs of wool undies from several companies, I find that the quality of this product far exceeds that of other companies. They aren't flimsy, they stay perfectly in place with no wedgies or riding up, and are just the kind of cut I prefer in a bikini. That being said, I echo the complaint that another reviewer made that they don't come in an XL. For comparison's sake, I take a size 6 in your average Jockey-type bikini, and got a large in the Ibex. They fit, but they're ever-so-slightly snug, and give just a little muffin top at the top band. This is not cool, and I feel like an XL would solve this problem. I really can't believe they aren't made in that size. This is the only reason I've knocked it down to 4 stars--otherwise I adore them. Honestly, Ibex!

        Wish these were cut better!

        • Familiarity: I've used it several times

        I like hipster style underpants. I wish someone made them in wool. Patagonia's bikini bottoms are a good style, but they don't make wool ones. I tried a pair of these, with high hopes. The fabric and color are great, but the cut seemed suspiciously steep to stay in place. The elastic was so tight, though, that they seemed to stay put initially. Alas, within 2 washes in cold water (no dryer) the elastic wouldn't dig into my upper thigh anymore (which was the only thing holding it in place since the bikini style is cut too sharply to stay put from cut alone) and they started to ride up. Busy nurses can't be adjusting their undies all the time, and nothing makes a long day longer like having your underpants shifting around under your scrubs. If these were cut in more of a hipster style, I would buy like 10 pair and get rid of all my other underpants.

        The Best!

          I have collected three pairs of these beauties.....They breathe, stay in place, dry in about 3 hours, never ever carry an odor, and last forever!! My daughter stole my first pair and did Outward Bound kayaking in them.....I think they got worn probably for the entire trip. They were faded after that...lasted another year or so until they developed a hole which frayed. One thought tho; - I wear a 4 or a 6 in pants/shorts and weigh about 120 lbs - 5/2". I prefer the Large cause I hate too tight undies. Medium would probably work, though, so I suggest sizing up by about one size....and no, the large is NOT loose on me...but no panty lines either. I have messed up and thrown them in the dryer and they really didn't shrink much.
