The rabbit EZ Sleeves deliver comfortable coverage perfect for sun protection on hot days or as an extra layer on chilly runs. These slip-on sleeves have non-slip silicone grippers and thumbholes to keep them in place so runners can stay focused on their run and not on their apparel. Furthermore, the rabbit EZ Sleeve utilizes Quick n' Fit fabric to help wick sweat away from the body and increase breathability for even more comfort out on the run.
