The UnD Shurt™ base layer is made to wear under a cycling jersey. Thin and form fitting, the UnD Shurt™ allows cyclists to dial in their clothing for specific temperature ranges without adding much weight or bulk to their outfit. Perfectly suited for temperatures from 40°- 80°F, UnD Shurt™ has a thermal property that keeps you comfortable on cool descents but doesn't overheat on climbs. Made from post consumer recycled polyester certified by Repreve®, UnD Shurt™ is easier on the environment, too.
The original product in the DeFeet UnDline™ of base layers, the UnDShurt™ has been around since 1997. For years we sourced our special fabric, sewed them in tiny batches, and shared them with the world’s top cyclists like a home brewer might pour friends a seasonal spirit from their only barrel. These racers returned, bringing more with them, and telling tales of how their lone UnDShurt™ had to be hand-washed every night during the season so that it would be ready the next morning. We knew we had a good recipe, we just weren’t that serious about selling them.The UnDShurt™ really does deserve a spot in every riders bag no matter what level they are. Our hand-crafted batches of UnDShurt™ are larger than ever. Step up and try our special concoction.You may end up wanting one of every model we make.
