These are Montbell arm covers I bought about two years ago. They're quite damaged from things like bushwhacking, but they're still usable. Size: M Color: Light Gray They look worn, but the Wickron functionality remains intact. I recommend them to those who understand that outdoor gear will inevitably get damaged. These thin arm covers are perfect for protecting your hands and arms and for sun protection during spring and summer trekking and hiking. They use Wickron® Cool, which offers excellent breathability and quick-drying absorbency. They're very cool and keep your skin dry, making them comfortable even in the summer heat. They also have a photocatalytic deodorizing function. You can adjust the fit by simply pulling on the elastic at the top, and they're designed to stay in place during exercise. The cuffs feature Spiral Slantec® cuffs for a comfortable feel against the skin.
