Rated 5 out of 5 by from Great on a run! I purchased these to keep me from getting too much sun exposure on my runs. I have been able to run in them 3 times now and am very happy with them. They keep my arms cooler than bare skin and keep me from having to slather on sunscreen.

What is the length/circumference of the two different sizes (S/M & L/XL)?

Here are the measurements for the ActiveIce Sun Sleeves. The upper hem measurement is a width with the sleeve laid flat; S/M - Length: 19.25", Upper Hem: 4.5" L/XL - Length: 19.5", Upper Hem: 4.75" The lower hem sizing will correspond with the glove sizing provided in the size chart.
