CASTELLI Core Seamless Base Layer

CASTELLI Core Seamless Base Layer

Seamless for comfort and surprisingly warm for its weight, the Castelli Core Seamless base layer is ideal in cool conditions, providing excellent moisture management.

Seamless construction promises stretch and comfort, but most base layers on the market have a nylon and Lycra® mix that feels comfortable when you put it on but then ends up feeling wet when you're actually riding, and you freeze when you stop. Castelli has worked hard to make this Core Seamless base layer keep you warm and dry, thanks to the addition of polypropylene and polyester yarns, while not compromising the stretch comfort of seamless. Castelli has found the sweet spot that also provides a nice level of warmth for cool to cold days.
