100% Merino Wool
Here's what other sites are saying:
When winter rolls around, you're gonna live in the 66 North Iceland Women's Basar Long Underwear Bottoms. These long-johns are ridiculously comfortable thanks to their close fit, flat needle stitching, and soft, elastic waist. But the secret to the Basars lies in their material-100% merino wool. Merino insulates even when wet, works hard to regulate your temperature, and resists odor better than most synthetics. So pull on these 66 North Iceland bottoms under your ski pants and enjoy a comfortable and warm day on the slopes.
