Houdini Alpha Zip Top
Here's what other sites are saying:
The Houdini Women's Alpha Zip Top provides midweight warmth to keep you nice and toasty on cold ski days. The front, collar, and sleeves of this baselayer feature recycled Eco Circle Alpha Base fabric that wicks and manages moisture at a quick pace, and recycled Delta Base fabric covers your back, underarms, and sides with extra moisture management as well as the stretch you need to ski comfortably. Both fabrics have Polygiene and pH pure antimicrobial treatments to keep this baselayer smelling as fresh as the day you got it. An athletic fit accommodates multiple layers for the frigid days, and a dropped back gives your backside more coverage. Alpha-seams ensure you don't wake up the next morning with chafed skin, and extended sleeves with thumbholes make sure your arms and hands stay warm the entire day.
