Do these sleeves really block UV rays?

Yes. REI rates the fabric UPF 50+, which blocks most UVA and UVB rays. Coverage depends on a snug fit with no gaps at the wrist or upper arm.

Will they stay up during a run?

Silicone grips at the upper arms help, and most owners report they stay put. Some wearers still see slipping or bunching, especially if the fit is loose.

How do I pick a size?

Measure your upper arm and bicep and match to the S/M, M/L or L/XL range. If you are between sizes, size down for a snugger grip.

Are they cooling or warming?

They are sun sleeves, not cooling sleeves. They wick moisture but add a layer, so they feel warm in hot, humid weather and are best for sun exposure or cooler mornings.

Can I wear them under or over a shirt?

Yes. They work over bare arms or pushed up under a short-sleeve shirt, and they pull off easily when you warm up.

What is in the package?

One pair of sun sleeves. Nothing else is included.

Our take on the REI Co-op Active Pursuits Sun Sleeves

The REI Co-op Active Pursuits Sun Sleeves are unisex arm sleeves in a polyester-spandex blend rated UPF 50+ for UV protection. They stretch in all directions, wick moisture and stay put with silicone grips at the upper arms. They suit runners, hikers and anyone who wants sun cover without a long-sleeve layer, and they pack small when the clouds roll in. Against plain cotton arm sleeves they add stretch and grip; against cooling sleeves they trade chill for sun block.
