DESCRIPTION

The purpose of this Castelli Prosecco Tech undershirt is to wick moisture away from your skin while adding minimal insulation for the cooler days when your riding intensity is high enough and your outer layers are warm enough.

The areas covered by the bib tight around the waist and on the back can get warm, so we used a lightweight PrimaLoft® fabric to help even out the temperature.

This undershirt works best when in contact with the skin. Both fabrics are very stretchy and the cut is slim.

On extremely cold days you use this as the first layer under a Flanders Warm undershirt or under a thermal cycling shirt. It is very effective in moving the body.
