Ultimately, the best type of climbing gaiters for you will depend on your personal preferences and the type of alpine sport you’re engaged in. If you’re doing a lot of hiking, for example, you’ll probably want a lighter and more comfortable gaiter, such as synthetic or Lightweight nylon gaiters.
Whereas if you’re doing mostly climbing, you’ll likely want something that offers more protection, for example Gore-Tex gaiters. These offer the best of both worlds, with lightweight construction and good protection against the elements. However, they can be quite expensive.
