Cooling UPF 50+ cover for the long trail.
Hours on an exposed track add up fast. IceRays give your arms UPF 50+ all day - and the harder you work, the cooler they feel, thanks to the moisture-activated fabric. No reapplying, no sticky sunscreen, no heavy long sleeves.

Lab Tested
Cooler arms, mile after mile
Out in the open there's nowhere to hide from the sun, and reapplying sunscreen every two hours on the trail is a hassle you don't need. Slip IceRays on when the sun's out and off when you hit the shade - UPF 50+ that does not need reapplying while it is being worn.
The moisture-activated weave means the warmer you get, the cooler they feel on your skin. They're light enough that you'll forget they're on - until you notice your arms aren't burnt.
