Best fitting gaiters I've had. Real snug and sleek fitting everywhere, absolutely no baggyness. Fit snug with a full size boot (Crispi Wild Rock, Guide, Kenetrek Mtn Extreme, etc..). Have only had them in the field a handful of times chasing cats yet so cannot judge the durability honestly. Kept snow out and I was dry below. Initial thought and expectation on material is high though. They can be kind of tricky to get on right away, zipper gets real tight around top of full size boot but I imagine there will be some stretch over time. Average sized male, 6' 185, size 11 boot. Small calves. Size large gaiter.
