Castelli Prosecco R Long Sleeve Base Layer

The Prosecco base layers are the mid-weight option and are made to wick moisture away from your body while adding a moderate amount of insulation. This all-around base layer can be used under a jersey to extend the comfort range to those first cool fall days, or even under a full jacket for your intense cold-weather training sessions.

Key Features

• ProSecco mid-weight fabric to keep you dry with a bit of insulation as well
