In 2010, De Soto introduced a new style of Polypro Jersey. New features include the speed-skater-style hood and thumb tabs, two angled side pockets, and contrast flatstitch seams, This piece is unisex.

It is made of Polyolefin, a new generation of polypropylene. It is the ultimate fabric to use as a first-layer for any cold weather activity. It not only keeps you warm, it is odor-resistant and has moisture-transfer properties that move moisture away from the skin to the surface of the fabric where it evaporates. It is designed to perform best when worn tight against the skin.

This is company founder, Emilio De Soto's single favorite garment. He travels with it everywhere. He uses it not only for running and for wearing in the winter under a cycling jersey, but also as his base layer for snowboarding, and even packs it in his carry-on for those chilly airline flights.
