It also encourages increased flow in the blood vessels in your knee, resulting in dramatically reduced pain and swelling both during and after activity.<p>And unlike other compression knee sleeves, Rhino Skin’s was designed with ergonomics and fit in mind, so you can rest assured that your knee sleeve won’t slip, slide, bunch or shift during your workout or daily movements. It’s even contoured to accommodate the natural bend of your knee. After all, what’s the point if you can’t depend on it to stay in place to do its job?<p>Our durable, neoprene construction is ideal for therapeutic fitness due to its unique properties: absorbent, heat insulating, flexible, stretchable, cushioning, lightweight and totally latex-free. It’s easily washable and holds up perfectly use after use without deteriorating in quality or function.<p>Rhino Skin stands by the quality of our products and nothing is more important than your satisfaction.
