I've worn OR Crocks for 25 years. They are a little noisy but somehow I've managed to kill quite a few elk while wearing them. I bought some Kuiu Gaters a couple of weeks ago and they seem to be modeled after the OR's with one improvement, a snap at the bottom of the Velcro. Just wearing them for a short time in the woods last weekend (it was too warm for a real test) they seem to be a bit quieter than the OR crocks. The four-way stetch material is pretty neat. Time will tell.
