Castelli UPF 50+ Light Arm Sleeves
The UPF 50+ Light Arm Sleeves more than live up to their name, since Castelli has reported that, although the brand officially rates them at UPF 50+, laboratory tests show that they block an impressive 99.8% of damaging UV rays.
They’re made from a polyester-based Solare fabric that serves the dual purpose of deflecting wind as you ride – without causing overheating – and wicking sweat while you’re working hard on a hot day. They’re therefore perfect for mountain climbing, protecting you in wide range of conditions.
Highly breathable and light, the sleeves are also practical and versatile, being small enough to fold into your pocket when they’re not needed and carefully constructed to minimise seams, promoting your long-distance comfort. Meanwhile, double-sided silicone elastic at the top ensures they’ll stay up reliably all ride long.
Key features:
- Solare fabric keeps the chill off without causing overheating
- UPF 50+ protection
- Polyester based for excellent moisture management
- Double-side silicone elastic at top for excellent grip
