Castelli Arm Skins

The Castelli Arm Skins are the solution for rides when you need to take the edge off of a slightly cool breeze or add a bit of sun protection. They also double as a great layering tool to be used under long sleeve jerseys and jackets.

At 50 grams, these minimal arm warmers are true extensions of your body and offer another layer of protection. Considering the low volume, they can easily be stowed away when the mercury rises. Seamless construction is durable due to the lack of seams and adds to the second skin like feel. Choose size and color.


  • Seamless and elastic construction
