Just took these on the West Coast Trail of Vancouver Island. Anyone who has done that trail knows the wet, muddy disasters that await you over every crest. On MULTIPLE occasions, my foot was completely submerged to the top of the gaiter and my feet stayed totally dry and protected. I'm talking, splashy, gooey, suck-you-down-a-rabbit-hole mud bogs. (Anyone done the trek coming from the south into Walbran Creek? Dear. God.) Many members of the group mentioned the "gaiter-invincibility" factor that gives you the confidence to splash through anything! These definitely gave me that. Washed them off every night in the nearby freshwater stream and they came out looking fresh as new in the morning. Outdoor Research products do not disappoint, and these gaiters are no exception.
