The roomier and burlier expedition version of the industry standard of gaiters from Outdoor Research. Larger circumference to accommodate cold weather and high altitude double mountaineering boots with more bulky clothing layers.  Entire inner leg is Cordura®. With a micro adjustable wide velcro front closure and an easily adjustable burly instep strap, these are designed to quickly adjust for a trim and variable close fit as clothing layers and needs change.
