This is the only pair of gaiters I have owned, so I can't really compare them to other gaiters. I do know that they are great for stream crossings, hiking in snow, or just keeping dirt and rocks out of your boots.
These gaiters are great. Super light weight and they keep the water and snow out! If you hike a lot in the snow then this is the gaiter for you! If you plan on climbing technical snow and ice with crampons you may want to upgrade to a thicker material. Otherwise keep it light and keep it simple with the Verglas.
