The Men's frogg toggs Grand Refuge 3.0 BF Wader is a boot-foot wader for on- and in-water performance. Stay dry while fishing or waterfowl hunting in a chest wader that knows what it takes to be in the outdoors. Specifically, it takes durable 4-ply polyester, heavy-duty nylon, and 5mm, 1200 gram Thinsulate Ridgebuster boots. Adjust the suspenders, tuck small items and gear into the pockets, and get outdoors.
