The Best Underwear Ever
February 24, 2011
These are by far the most comfortable, breathable, odor-resistant all-season underwear around. The fit is excellent with its low rise design and the wool is ultra soft and non-irritating. These have definitely become a staple for hiking, camping, snowboarding, and everyday wear.Pros: Great design, Build quality, Performance, Ease of use, odor resistant, breathable, wicking, low rise, Cons: Cost

Wool undies!! I have fallen in love with merino wool for its temperature regulating abilities and have several base layers --shirts, leggings, socks -- in this fabric. However, this is the first pair of wool panties I have purchased and I am VERY pleased. The wool is silky and smooth and the cut fit much better than I anticipated. As noted in the description, they are *low* rise and just barely cover things completely in the back. Despite this they are super comfortable and stay put during active pursuits and do NOT pick up funky body odors like synthetic fabrics. I bought them mainly for hiking and backpacking -- but I find them so comfortable that I reach for them for everyday-wear as well. They are perfect with low-rise jeans). I am almost 5'10" and lean (130lbs) -- size Small fit perfectly. I hand washed them and they dried quickly overnight (but I live in the desert and can't say how they will do in humid conditions). Awesome panties!Pros: Build quality, Performance
