Women's Thermal Set - Quarter Zip Top and Thermal Leggings - Base Layer

Cotton long johns soak up sweat on the first climb, then leave you cold at the top. This women's thermal set is a seamless quarter zip top and full-length thermal leggings in a close rib knit, made to go on first under your ski pants, hiking pants or jeans, so you stay warm without the bulk.

Both pieces are knit from 68.4% nylon, 24.4% polypropylene and 7.2% elastane. The ribs hold a thin layer of warm air against your skin, and polypropylene absorbs almost no water, so sweat moves on to your next layer instead of sitting cold on you when you stop. Knitted zones at the waist and knee help the set stay in place as you move.

Wear it under a ski jacket on the slopes, under a fleece on a frosty hike, on its own for an early run, or around a cold house in the evening. The short zip on the stand collar opens to let heat out on the climb and closes again on the chairlift.

Key Features:

• A close rib knit holds warm air next to your skin and stays thin enough to hide under ski pants or jeans.
• The polypropylene blend moves sweat away from your skin, so you stay drier on the climb and warmer when you stop.
• A short quarter zip on a stand collar lets you vent heat on the way up and seal out the wind on the way down.
• Four-way stretch from 7.2% elastane moves with every turn, step and stride without pulling at the knees or shoulders.
• A seamless body and raglan sleeves leave no side seams to rub under a backpack strap, a bra strap or a ski jacket.
• The soft synthetic knit has no wool in it, so there is nothing to itch.
• Matching top and leggings in White, Black and Sky Blue, in women's sizes S to 2XL.
