These sunsleeves work very well for cycling. They're a little thicker than some that I bought from Performance Bike, but they actually keep me cooler. When I moisten them on a hot day, they retain the water longer, for more evaporative cooling. On cool mornings they keep me warm. I prefer the white ones, as they're most effective at reflecting the suns heat (although they'll probably be harder to keep clean).
I ordered these for a hiking trip in the Grand Canyon and they were terrific. I loved them. They somehow had a cooling effect even though they were skin tight. I love how easy they are to pull on and off. I just tucked them in my pocket when not wearing them. I'm 5'10" and don't have big arms. They're very snug around my bicep and go down about an inch beyond my wrist. I just rolled them up. I'll also use them biking this fall as a layer of warmth that can be removed as I get warmer as I ride.

Love my sleeves but they fall down because you only have S/M. I really need a small or maybe a kid's size. I am 5'2" and 110 lbs.
I have been wearing my fossil colored sleeves for a month now and love them. They tuck under quarter length sleeves and look like thise shirts with double sleeves. The medium size stays up well unless you have really slim arms. The sleeves are so much cooler than wearing an entire sun shirt. I also discovered by accident when I washed my sleeves and they hadn't dried yet that if you wear them damp, they really cool you off.
As soon as these sleeves arrived I wore them working in the garden. Total protection for my problem forearms. My only regret is not purchasing them sooner. Great fit, easy wash.
