Chill-Its Unisex Adult Performance Polyester Knit Cooling Arm Sleeves, 1-Pair, M,Blue

My husband loves them. He works construction and he says these are life savers in the heat.

This is the second time we've purchased these sleeves: first, in 2020 prior to size changes; second, this current sizing. From experience, we purchased XXL from the get go, which now fit the standard 11" bicep but, is still a tight, tight fit for biceps larger. The sizing of the XXL proportions also need work. If the band fits the bicep for our crews, the arm is much too large, therefore, the extra material moves around as they work. This also contributes to slippage, which is far from ideal. If these sleeves were meant to be worn lower on the bicep, fine, then make the sleeve shorter. If they are meant to be worn halfway on the bicep where typical short-sleeved shirts cut off, then make the sleeves larger on the bicep side.

This was my second pair and I’ll continue to get more. I work outside in the Florida sun 5 days a week. They keep the sun off my skin and keep me from overheating. Depending on your needs, these sleeves are definitely worth it.

These things are awesome. I use them at home doing yardwork; when dry they wick moisture away from the body, keeping me cool. When wet they felt like my arms were stuck in an air conditioner. Plan to use on the golf course next!
