DeFeet UnD Shurt Tee Base Layer

DeFeet has been producing one of the best base layers before riders even knew what they were. The UnD Shurt's simple and almost seamless design is comfortable, thin and offers great performance. The snug and anatomic fit maps your body and will not bunch underneath your jersey.

The UnD Shurt Tee is constructed from DeFeet's 3oz knitted mesh MicroSupreme acrylic fiber. These fibers produce a unique polarity of acrylic which quickly draws moisture away from your skin to the outer layers of the base layer and then to your jersey. Keeping you dry and cool is what the base layer is all about. This fabric offers almost unmatched comfort due to the soft and fine hand which is much akin to cashmere. All ends are double stitched and hemmed for durability when riding and washing the garment. The combination of fit, comfort and performance is the perfect trilogy in creating a fantastic base layer and the UnD Shurt excels in all three fields.
