Ergodyne® ProFlex® 670 Wrist Sleeve Wrap The Ergodyne ProFlex® 670 Wrist Sleeve Wrap is designed to provide light to moderate support for office and industrial use. Ligthweight single layer black neoprene fabric stretches four ways to provide a uniform glove-like fit and support without restricting muscle activity. It can be worn with or without the removable 2" woven elastic strap for moderate to firm support. Closed cell structure promotes warmth, and hook and loop closure adjusts fit and tension. Ambidextrous sleeve wrap is machine washable.
