Rated 4 out of 5 by from These fit well I tried on the large in store, they were too small. I have big biceps and forearms. I ordered the xl from the store and they were sent to me. These fit well. I have not worn them at work yet. I bought them because my company requires me to wear long sleves when climbing poles. These are mote comfortable than a long sleve shirt in the summer.

Rated 4 out of 5 by from Prevents sun damage on long rides Bought these for long rides. Dislike sunscreen which attracts grime and insects. Sleeves feel cool and light even on a hot, sunny day. I bought medium but should have bought small. They have no elastic and must be upheld by muscle.

Rated 1 out of 5 by from They weren't broke! Why'd CO-OP break it? Four years ago I bought a great pair of Novara sun sleeves. I wore them out. Bought a new pair last year. I've been loving them. Went to buy a new pair the other day and was faced with the new redesigned CO-OP version. Medium was too short and tight. Large was the right length but had no elasticity or grippiness on the top cuff which resulted in saggy-baggy and wouldn't stay up so I had to return them. The quality over all seemed good. The price point great.. but what's the point if I can't wear it? I hope CO-OP is as open to feedback as the little salses cards claim they are. Not everyone has the biceps to hold up your baggy sun sleeves, CO-OP! Incidentally, I bought a pair of CO-OP bib shorts which are excellent and a CO-OP jersey styled t-shirt (MADE IN USA no less) which I really like.

Rated 4 out of 5 by from Nice look good fit I need sun sleeves when I ride my bike ... I burn easily and I live in southern Arizona, USA. My old ones were stretched out, torn, and I needed new ones. These do the job; they fit well and look sleek - makes them modestly more aero, I guess. They are a little less porous, so they feel warmer than my old ones, but keeping the sun from my skin beats this little problem. I will buy them again.

Rated 4 out of 5 by from I Hate Goopy Sunscreen...! I hate to put sunscreen on my body, but I was going to be riding 75 miles in the hot mountain sun, so I forced myself to buy these arm sleeves. They were awesome! Lightweight, so I completely forgot that I was even wearing them! And when I removed them, I didn't have even one red spot! Normally I get completely fried, so this was a nice change of pace...! Love the sleeves...!

Rated 5 out of 5 by from Early morning ride comfort I favor bike rides at dawns early light in N Georgia. The sun sleeves have provided more comfort on the cooler mornings and the flexibility to remove them as the sun clears the tree tops and the heat rises that contribute to another great ride. Highly recommend for cyclists needing temporary comfort and are easily stuffed into a back jersey pocket when not needed

Rated 3 out of 5 by from Sun sleeves useful Easy to wear. Actually cool on covered arms on sunny warm day. Effective in reducing Sun exposure. I have yet to wear them on a really hot day on the bike. We'll see then if the sun sleeves work well or maybe back then to sun screen.

Are these the thicker sun sleves for warmth or thinner for cooling? I want cooler. My arm length is 17 1/2 inches. What size should I get?

Asked by: Qball
​These sleeves are intended to help wick moisture away and keep you cool with the vented panels; for an arm length of 17.5 inches we recommend a size Medium.

From where to where on the arm do I measure?

Asked by: rbreiten
With your arm straight, we recommend measuring the length of your arm from your armpit to your wrist.
