Like their namesakes, the Crocodiles Gaiters have been around forever. And because they're tough as nails, they've hardly changed: waterproof, breathable GORE-TEX® upper and super-durable Cordura® inner leg and boot cover. The instep strap is now triple-bartacked BioThane® webbing, and an additional tab holds down the front opening, but otherwise they remain as they were when they first appeared. The fitted design and durable, waterproof fabrics are as effective now as ever, which is why the Crocodiles are the world's most popular gaiter.
