CASTELLI UPF 50+ LIGHT ARM SLEEVES are a great accessory for cyclists who refuse to get sunburned on every ride.
They offer excellent protection against UV rays, tested UPF 50+. Their lightness also limits heat gain for optimal riding comfort.
The polyester design provides a fabric that efficiently wicks away perspiration. Also, to ensure they stay in place on the arm, they have silicone strips on the top.
