The Mons Royale Proximity Merino Legging puts merino and Tencel(TM) against the skin, where temperature regulation matters most, and wraps them in a nylon exterior for durability. These women's merino wool leggings carry that split construction from the gym floor to the hiking trail, so one pair covers a strength session and the climb that follows. What Our Gearhead(R) Experts Are Saying:"The fabric wicked sweat and dried fast enough that these leggings never turned clammy or clingy once I stopped moving. The flatlocked seams lie flat instead of ridging up, so nothing rubbed through a long session."
