Castelli Core Seamless Short Sleeve Base Layer Description:

Castelli engineered the Core Seamless Short Sleeve Base Layer to provide excellent moisture management in cool to cold weather conditions. A mixture of polyester and polypropylene moves moisture away from the body with absolutely minimal moisture uptake. The fabric is soft next to the skin and provides great temperature regulation in mild conditions. It's not for hot temperatures but it does work as a first layer even in cooler temperatures, while the seamless construction keeps it extremely comfortable.


  • Seamless lightweight drying layer with an exceptionally stretchy fit
  • Ideal for cool to mild conditions when keeping yourself dry is the priority
  • Unique mix of polyester and polypropylene provides maximum moisture management with significantly lighter weight
  • Wide neck opening to fit under short-collared jerseys
  • Temperature Range: 46° - 68°F (8° - 20°C)


  • Gender: Men
  • Fabric: Polyester/Polypropylene
  • Sleeve Length: Short Sleeve
  • Color: Black
