FAQ

How is white different from black for sun protection?

Both colors are rated UPF 50+. White reflects more visible light so the sleeves stay cooler to the touch on hot rides. Black absorbs more heat but hides road grime. Pick whichever you prefer for matching your kit.

Are these warm enough for cool starts?

They are designed for sun protection more than thermal warmth, with a 50 to 64 degree F rating. If you need real warmth on a cold start, look at a heavier arm warmer instead.

Will the silicone grip leave a mark?

The double-sided silicone is designed to grip without pinching. It holds the sleeve in place against your skin and your jersey cuff at the same time.

Can I pack these in a jersey pocket?

Yes. At 57 grams for the pair, they fold down small and stash easily when you do not need them.

Best For

Long sunny rides where sunscreen wears off, climbs that start cool and finish hot, and riders who want UV protection without the extra insulation of a thermal warmer.
