I have own a pair of these gaiters for quite a few years now and would have to say they are one of the best bits of kit I have ever purchased. They have proven to be extremely hard wearing through the most rugged terrain but at the same time are comfortable to wear which I have often found lacking in some other gaiters. Breathability is also excellent and because of the fit over the boot really does provide a watertight seal keeping feet dry. One point that I would say is to just be careful with your choice of footwear as these do not fit every boot, though i have found them to fit most pairs I have worn.
