Castelli Prosecco R Ls Base Layer


The midweight Castelli Prosecco R LS Base Layer is made for cool conditions or high-intensity cold-weather rides where wicking moisture away from your skin is a priority. The hydrophilic Prosecco treatment spreads the moisture out over a large area for quicker evaporation. Two different weights of fabric are merged, with a thinner layer used where it will be covered by your shorts/tights or bib straps so that you don't have too much insulation where you don't need it. Anatomically cut with flat stitching at hem for comfort.


  • Prosecco mid-weight fabric to keep you dry with a bit of insulation as well
  • Temp Rating: 6°-18°C / 43°-64°F
  • Cut to fit under any Castelli jersey
  • Flat seams
