Simple but effective
Got the gaiters for a basic mountaineering trip around Mount Cook in New Zealand. I put them through their paces with everything from aggressive plants to rock scree faces to knee deep snow to crampons.
Construction isn't as thick and bomb-proof as other designs out there (crocodiles) but that also keeps the weight down. They didn't show any signs of wear and tear, and kept all of the snow and rocks out of my boots. Upper did get wet after extended snow exposure, but socks and boots stayed dry. They were not soaked uppers, but just some patches where snow got stuck in wrinkles (not a big deal).
