Safety in the mountains often equals moving quickly over varied and difficult terrain. Outdoor Research designed the Verglas Gaiters to carry light and travel fast. Whether you'rekicking steps up a fragile snow finger, skinning across a glacier, or negotiating a hairy bushwhack, you can't afford to snag, rip, or be bogged down with snow and debris. The asymmetrically-cut boot section provides a secure fit with leather hiking boots or plastic mountaineering boots, making the Verglas functional as much as a stout backpacking gaiter as it is a serious mountaineering gaiter. The ultra-light, waterproof, breathable 3-layer Ventia leg section and the coated 500d Cordura boot section make this gaiter a more packable alternative to the OR Crocodiles. A nylon-supported rubber instep strap pulls the gaiter down and flush with your boot to seal out snow and debris. Offset the 1.5in-wide hook-and-loop front closure if you need to make room for insulated pants.
just like the crocodiles except made of a lightweight material that will put up with less torture.
I only buy these gaiters.
Sure, crampon points will tear them up quickly because they are made of a thin and lightweight material... but i don't know a gaiter that won't get torn up by crampons, unless you have steel gaiters.
I use these because they are very light and pack down to nothing. I can take these just in case and not feel back about hauling more weight.
The verglas keeps snow and mud and derbies out of boots just like a gaiter is supposed to. And opposed to what seems logical they take a beating fairly well. I have a couple of tears that I've taped up but other than that they're in great shape, and that is after 2 years of climbing climbing climbing!
If you're worried about these being too flimsy and fragile, the crocs are a great option for you. But if you don't mind have a slightly more fragile gaiter and using duct tape to repair crampon slices, get these... they are cheaper, lighter and in the end all gaiters will fall prey to the dreaded crampon!
