The GoFit Power Handles- M Style, are made of heavy duty, premium components. Durable handle grips have smooth rubber texture, so you keep your grip during exercise. The surface feels almost tacky to-the-touch, giving you the control you need. This handle has a wider 1 5/16" diameter core and caters comfort to larger hands or those who like a "beefier" feel with their handles. The nylon webbing and stitching are heavy duty and durable for optimal performance. Maintain your hold while having freedom of movement with the grips' rigid, tubular design.
