WayCool™ Arms is rated 4.8 out of 5 by 5.
Rated 4 out of 5 by from Short but Effective The sleeves have a great soft feel, flat seams and solid constructions. They do a great job cooling in warm weather and they provide a little insulation on my colder runs. The sleeves are about an 1" shorter than other brands I have used leaving a some wrist exposed. The sleeves are not cut for even my moderately muscular build: the bottom of the sleeves near the wrist are loose to the point where the fabric is not actually against my skin, and it is very snug around the bicep while fitting the top and elbow perfectly. The gripper at the top is great, no slipping even during running. I have not tried the phone pocket yet. Overall a good sleeve that could use a male/female specific cut rather than a unisex the just doesn't work.

Rated 5 out of 5 by from Perfect! I am female, 5'6 @ 136 and ordered size medium. The sleeves fit perfectly and keep my arms cool. They truly work! The material feels like soft cotton, unlike the PI and Novara which is a tight slick material with a wide band. I am very happy with the MH arm sleeves!!

Rated 5 out of 5 by from Awesome These do the job on the trail and running. Comes in handy when the wind whips up a cold breeze and when the Summer Temperatures are 90 degrees plus. I just wished both sleeves had pockets.

Rated 5 out of 5 by from Amazing To be honest, when I first saw these "gimmick" was the very first thought I had, but they were on sale so I didn't have too much to lose. When they came in I opened the package and pulled them on. Immediately, with them still on I bought two more pairs in the same size! I wear them on the water, on my bicycle, and even at work! It's awesome to be able adjust my UV protection and my cooling ability on the fly between these sleeves and a short sleeve shirt. It's like what modular pants/shorts systems should have been but for your arms instead. They really are cooler than bare arms. I unreservedly recommend these to everyone. The only thing I would do differently is not wait as long and buy them all together next time!

Rated 5 out of 5 by from Cooler than you think The weight or thickness fool you into thinking no way they would cool in warm temps but they DO! The sun protection is mandatory for me from working out side is part of my existance. I'm in full motion constantly and the arms move as if a second skin. Heavier than other similar products from other manufactures but the cooling properties work excellently.
