Cotton/poly blend wristbands to wear under your grips (please read on if you wear hook & loop/velcro grips). "Large" refers to the length (which is approximately 4") and not the width. These are stretchy and will fit almost everyone but these are especially nice for smaller wrists. These large wristbands work under ALL styles and sizes of our grips but because of the polyester blend, these tend to unravel easier when you are using hook & loop (velcro) grips. Hook & loop grip users, we think you'll like our Small 3" wristbands, or the PRO 5" better as the velcro doesn't grab those like it does with this particular 4" style.
