Layered warmth.

Winter layering choices just got a whole lot easier with Castelli's Men's Prosecco Short-Sleeve Baselayer. Finding a balance between too-light summer layers and overbearingly heavy fabrics, this mid-weight base layer tucks stealthily under your favorite winter kit for consistent warmth whether you're hammering intervals or out on a social spin. It's fashioned from Castelli's dual-layer Prosecco fabric, which ushers moisture out and away from your body for quick evaporation so you stay comfortable and dry.

  • A mid-weight baselayer with wicking prowess
  • Hydrophilic treatment pushes moisture away
  • Streamlined fit sits comfortably under winter outer layers

This base layer does a great job keeping you dry and warm on those very cool days. I have used it 50 degree weather works great under a jersey and a lightweight, long sleeve outter jersey. Definitely recommend.
