UPF 50+ Light Arm Sleeves

Castelli UPF 50+ Light Arm Sleeves

Stay cool and protected from the sun with the lightweight Castelli UPF 50+ Light Arm Sleeves. While these skins are rated at UPF 50+, in laboratory tests they actually blocked 99.8% of damaging UV rays. This was accomplished by using the lightweight and highly breathable Solare fabric.

These sleeves' polyester base stops you from overheating by allowing an optimised level of airflow while also actively wicking moisture away from the surface of your skin.

Castelli has purposefully kept the sleeves' construction very clean in order to remove any unwanted chafing from seams. Double-sided silicone grippers at the top of the sleeve make sure the skins hold their comfortable position on your arm.
