I'm actually a dude and I bought these because they were being sold at a crazy clearance price and the men's base layer bottoms were twice as expensive. I chose the XL (waist size is 34 inches) and these fit perfectly and are super cozy and comfortable. I honestly think the only difference between t... Read More

    These are a great base layer. Not scratchy and are nice and warm. I did dock a star because of sizing - I ordered my normal size and these bunch up when I put a pair of jeans over them. Seem to run a bit large and stretch out a bit.

    I was skeptical about the no-itch wool, but these are truly no itch! I am 5'6" and I ordered a medium, they were a little snug in the thigh but loosened quickly into a comfortable fit.

    This bottom base layer is form fitting. While it will be good to wear under pants that aren't roomy, I'll need to take care that they never slip into the dryer. I am a 6/8 with fairly thin legs. Haven't worn full day so they may stretch out a bit.

    These leggings rock my world. I plan to buy more in a variety of colors.
    I wore these under shorts during a recent trip Alaska, and they performed better than I could have ever dreamed. I was backpacking in the back county and had to cross a lot of braids and glacial streams. These held heat and dried incredibly quickly. And when the sun came out, they were totally breathable. The power of wool!
    I admittedly wore them a few days in a row.
    I'm size 6-8 and the small fits perfect.

    I bought these to replace a pair of worn-out Smartwool midweight bottoms that I wear as pajamas. They're okay. Good quality, but nothing spectacular so I'm glad I got a good price. I'm 4 foot 11 and a size 8. I ordered the large, but could have gotten the medium and been happy. Would definitely recommend the medium if I was going to wear them as a base layer. They have a thicker and smoother feel than the Smartwool, but the same warmth. Some crotch pilling after the first wash and wear.

About Icebreaker

Crafted using only the finest merino wool grown in New Zealand’s Southern Alps, Icebreaker clothing is known around the globe for its incredible comfort and performance. Unlike synthetic fabrics developed in a lab, Icebreaker merino wool is grown, cultivated and field-tested in the mountains. Designed to offer exceptional comfort during a range of outdoor sports, Icebreaker underwear and apparel naturally resists odors, regulates body temperature, wicks moisture and dries quickly. Superfine New Zealand merino wool is also much softer than traditional sheep’s wool, which means no itch. Icebreaker socks, long underwear and base layers also come in a selection of weights to keep you warm without overheating. Ready to join the merino revolution?
