Yeah, I suppose they're breathable. Haven't had wet legs like the OP.Isn't there like a nickel sized piece at the bottom?
Is the top webbing strap to cinch 3/4" or 1/2" wide?
Are they breathable?
Not sure about the other stuff. I think people might be getting into the weeds on gaiter specs. I've had three different brands and they were all the same - waterproof, breathable, and last a long time. I like Hillsound because they don't have Velcro. Other than that, they're gaiters.
