The Un-D-Shurt is a core piece of the DeFeet Un-D-System.
Un-D-Shurts are very thin; the ideal initial layer for any active
sport. The precise fit does not bunch up or take up too much space
under other loose-fitting apparel. Need more warmth? Add another
Un-D-Shurt.
Layering properly for cycling, running, and other aerobic sports
is critical for comfort anbd performance. DeFeet developed the
Un-D-System to be the most precise base layer system available.
Un-D-System components are designed specifically to function in the
environment between the user's skin and other garments.
