$12.99 knee-high nylon gaiters Ocean State Job Lot
Just back from first hike in these. Upper part nylon, lower part ripstop polyester. Top drawstring at center rear, less likely to catch on shrubbery. Boot strap of neoprene attaches by friction buckle on each side of gaiter: very easy to adjust or replace strap. Elastic gathers behind ankle and around heel of boot, which makes them snug enough down there. 2" wide overlapping velcro strip closes gaiter at front, with backup snap at top and bottom. Lace hook at bottom secured by two rivets. Someone has learned what works before they wrote the specs.
Not insulated or totally waterproof (you can add that), but for a lightweight nylon gaiter that will keep the snow out and stay cool in summer, I think this one is too good to not check out. Creag nan drochaid
