Love these bikinis! This was my first foray into wool underwear (having already converted to wool socks, wool shirts, wool leggings, wool buffs....), and I am so happy that I took the plunge. They are soft and silky, and the fit is great. I am 5'6"/130lbs, size 6-8 on bottom (wide hips, muscular thighs and a definite booty), and the M fit great. The leg elastic doesn't cut into my thighs or butt, so panty lines are not an issue. I will never go back to synthetics again!

Pros: Great design, Build quality, Ease of use, Cons: Cost

I love these undies! They are great for travel, hiking, and working out. Easy care, fast drying. The fit is prefect, and they are snug without leaving lines so I can wear them under "regular" clothes too. Like other Icebreaker items I own, I am very satisfied with these bikinis.

Pros: Great design, Build quality, Performance

great for outdoor activities!

Great underwear for backpacking or bicycle touring as they don't ride up and hold up extremely well. They are also not bad to double as a bathing suit for that spontaneous dip in the river!

Nice but not as good as the hipster
September 25, 2011

I'm a huge fan of icebreaker. I have several pairs of Icebreaker's hipster bikini, and since I can't find them anymore, decided to try this bikini. I like it, but it's not quite as comfortable as the hipster because I found it to ride up once in awhile, which never happens with the hipster. It's a lovely, high quality Icebreaker product, but will probably not buy again if I can get the hipster instead. I'm 125 lbs, with narrow hips, and the small fits perfect.

Pros: Build quality, Cons: rides up

These bikini Icebreakers are great! Very little if any riding up ie hiking and sweating. Wash and dry very quickly! Don't sweat in them- overall best bikinis for hiking, anything

Not itchy at all. Great fit, hold up well and very comfortable. Best thing is they don't hold odor. Wash and dry fast. They may be expensive, but worth every penny!

Pros: Build quality, Ease of use

5 feet, 125 lbs, medium fit well. Good coverage on the backside. Low rise makes it contemporary. Function well, breathable and look nice. They are so soft, it is hard to believe they are wool. They are expensive, which is the downside, but I liked them so much I got one in every color.

Worth a try....

Not itchy at all even though it's at the most sensitive area. Perfect fit; not tight nor to loose. Soft yet sturdy. Also the curved style is extremely flattering with a great fit. They are expensive but will worth the investment.

Pros: Great design, Build quality, Lasts forever, Performance, Great value
