Theta Pant
OVERVIEW
Waterproof / Breathability Rating:
20K/20KTheta Pant
Bombing down the mountain, you need a pant that’s built tough; so we built you the Theta. After all, you won’t quit — and neither should your gear.
We’ve put seven decades of Alpine heritage and Aspen engineering into the Theta Pant. The result is a ski-ready pant built to stand up to the harshest winter conditions, while maximizing performance, durability, and comfort.
The Theta Pant is made with state-of-the-art technology and comes feature-loaded to take on any mountain. By pairing Toray® Dermizax DX™ 4-way stretch fabric with reinforced construction, you’ll get all-weather performance without sacrificing the dynamic movement you need to perform on the slopes. When the temperature starts dipping, PrimaLoft® Gold 40gm insulation will keep you warm day-in and day-out.
