Defeet Un-D-Shurt Sleeveless Undershirt - White [Size: M]

The DeFeet UnD Shurt base layer is thin and form fitting, allowing riders to dial in their clothing for specific temperature ranges without adding much weight or bulk to their outfit.

Perfectly suited to temperatures from 40-80 degrees Fahrenheit (5-26 degrees Celsius), 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 DeFeet sourced their 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. DeFeet knew they had a good recipe, they 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. DeFeet's hand-crafted batches of UnDShurt are larger than ever, so step up and try their special concoction. You may end up wanting one of every model they make.

Care notes: Machine wash cold with like colors, no bleach, no softeners, tumble dry low
