Everyone could use a little support now and then, and particularly when you're spending long hours wading, your back would appreciate it. The Simms Backmagic Wading Belt was designed by orthopedic physicians to help reduce back fatigue and strain throughout the day. The high-density neoprene and structure mesh construction is flexible and self-adjusts to provide anatomical support without you having to constantly adjust it. The hook-and-loop closure lets you find a precise fit, and won't release or stretch if it gets wet.
