Outdoor Research was founded on the X-Gaiter. OR's first ever product, inspired by a frostbite fail on Denali, was the first of its kind. Built for the most extreme weather and encapsulated by a rugged, insulated interior with an easily-adjustable, and easy-to-repair instep strap. So naturally, industry-revolutionizing classic builds off this legacy of alpine protection with a few improvements: Unprecedented warmth, streamlined fit with minimal bulk, and an incredibly lightweight construction that's versatile enough to suit your favorite seasons and mountain sports. How did we manage to pack all that in? A 90D ripstop stretch double weave provides rugged durability against the elements that still allows for a flexible on-off design, enhanced by a stretchy and snug neoprene along the ankle and back of calf. A neoprene circumference grips the edge of your boot and stays put without slippage, and a velcro entrance allows easy manipulation - even when dexterity is compromised by large mitts. Its versatile design balances the best and worst qualities of crampons with a pliable lip that secures over your toe and heel welts, while an exterior silk screen print acts as a scuff guard to resist punctures caused by these fail-safe tools. Trusted by NASA, the compression-resistant and advanced warmth of PrimaLoft® Aerogel insulation covers toes and entire lower half of boot. Finally, an adjustable shock cord is easily manipulated and field-maintainable in the event of any emergency. Perhaps the best quality of the newly redesigned X-Gaiter is its total versatility. Compatible with mountaineering boots as well as ski touring boots, the X-Gaiter does the work - and provides the protection - of an 8000m boot without the cost, bulk, or limited use case. There's not question about it: This dramatic transformation of the best legacy footwear protection in the industry is going to be the best choice for every single one of your next alpine objectives.
