The Castelli Prosecco Tech Short Sleeve Base Layer aims to wipe sweat away from your skin while adding some insulation for those cool days when your intensity in the saddle is high enough and your other outer layers are quite warm.
The areas covered by the tights around the waist and upper back can get hot, so a lightweight PrimaLoft® fabric was used to help regulate the temperature.
This underwear works best when in contact with the skin, so both fabrics are very stretchy and the cut is snug. On extremely cold days, you can use it as a first layer under a second layer Flanders Warm or under a thermal shirt. It is very efficient in evaporating sweat from the body.

• Proprietary stretch rib knit 100% polyester main body fabric with Prosecco hydrophilic treatment for maximum wicking.
• PrimaLoft® panels at waist and back where bibtight covers upper body, to reduce uneven insulation.
• Crew neck closure to fit under short-collared jerseys.
• 10°C/20°C.
