Castelli's Prosecco RSS Baselayer is a mid-weight all-around layering option, made to wick moisture away from your body while adding a moderate amount of insulation. It can be used under a short-sleeve jersey to extend the comfort range of those first cool fall days, or even under a full jacket for intense cold-weather training sessions.


  • Prosecco mid-weight fabric to keep you dry with a bit of insulation as well.
  • Cut to fit under any Castelli jersey.
  • Flat seams for improved comfort.
  • Weight: 112g.
