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 a traditional high-altitude boot without the cost, bulk, or limited use case. There's no 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.
