I've used these once, bushwacking in the White mountains of New Hampshire. I originally bought the OR summer gaiters but they would bunch up like an accordion. I liked the idea of a tightening strap around the calf and a durable strap for the heel. The only thing I didn't like was the tightening strap, occasionally the excess would get caught on branches.
