Improved circulation and support. That’s what you’ll get when you use these Essentials Women’s Compression Sleeves by SKINS. Athletes in all sorts of sports, from triathlons to baseball to fishing to rugby to cycling, are starting to use these. Why? First, the compression has the effect of increasing oxygen delivery to active muscles (circulation) while in motion and reducing lactic-acid build-up for more power and less recovery time. Second, the the support on your key muscle groups reduces movement and focuses direction for less vibration in your muscles and therefore less soft tissue damage and less soreness after exercising. These also use a Spandex-blended fabric that has a wicking effect to keep your arms from getting sweaty, and, by the way they provide UPF 50+ protection. And one more thing, SKINS makes them specifically to fit women with a slightly different design and cut for both right and left arms.
