Description

The seamless silky soft texture of the fabrics used in Castelli’s Core Seamless Short Sleeve Base Layer are exceptionally comfortable close to body. The lightweight, soft base layer insulates body heat while its stretchy materials fits snugly under a cycling jersey. To ensure an even better fit, designers made a wide neck opening so it’s flatter along the seams. Polyester quickly moves moisture to the outside of the material so sweat evaporates and you stay dry. The Core Seamless base layer keeps you warm and dry in cool fall and spring bike rides enhancing your body’s ability to perform.

  • very good, wicks away sweat
Color: White Size: Large-X-Large
I cant say its better then others (have some EKOI which also work) but very good base layer, it certainly keeps the skin dry. I ended up buy two of them since they work well.

  • Great Performance
Color: White Size: Small-Medium
Snug fit under jersey does not get in the way, and keeps you very warm.
