Edward M.wrote a review of Outdoor Research Crocodiles Gaiter on August 13, 2017
Familiarity: I've used it several times
I bought these for Search and Rescue, and I tried them with a variety of boots - Irish Setters (from the late 90's), Danner Hood Winter Lights, and Danner Acadias. The metal tab that is supposed to capture the bottom lace doesn't do its job.
The material has a bias towards pulling up, away from the toe/lace, and the gaiter will slip down my leg just a bit (1"?) - that's just enough for the tab to come off the lace. I considered crimping the tab over a little more to more tightly capture the lace, but why?
Beyond that, at least in dry conditions, they do keep 95% of the dirt, stickers, poison oak, and crud off your boots/lower leg. I bought the size indicated by my boot size, but I'm not sure a smaller size would work any better.
