Chrono UV Arm Sleeve

4 out of 5 stars
1 Review


Size Chart


Well armed.

The reasons for slipping on Giro's Chrono UV Arm Sleeves before a ride are as numerous as the skin cells they cover up. Being a cyclist entails spending an inordinate amount of time in the sun, with training sessions, century rides, and races routinely extending our exposure from five to 10 hours at a time. We owe it to our skin and our future health to alleviate the potential for damage, and the Chrono UV Arm Sleeves provide UPF 50+ protection to reduce the harmful UV rays hitting our skin.

,p>While they're not as light and airy as riding with bare arms, they're still light enough for all conditions but the most sweltering summer days, and their high-stretch synthetic material and spiral knit construction efficiently wicks moisture, keeping you free from soggy slop and the sun's punishment simultaneously.


  • Sleeves to protect endurance athletes from UV rays
  • High UPF keeps the sun's punishment to a minimum
  • Stretchy, breathable construction for hours-long comfort

Fits well, but fabric MIGHT be warm

These fit well and have much less "bunching" on the inside of my elbow when compared to the OR Bugout Sun Sleeve. The fabric is ribbed (I'll go faster, he-he) and feels a bit warm when I put them on. I have a slight concern they might be warm on a long ride on a hot day--that hasn't been the case on the two short rides I've taken (~20 miles each in ~90F temps).
