Made of polyester/nylon/cotton, these belts have been valued for a bit in the "outdoor world" for their light weight, durability, and range of tension. Without holes, the belt can be tightened to fit almost any size. You can swim with it on too, and look good doin' it. And we both know that's the important part.Love the top right guy, the Canoe Belt from Wintergreen Northern Wear, made in Ely, Minnesota (a la 10engines).
