Get the best from gaitors
Q Should gaiters go over or under my waterproof trousers? Dale Bundock, via Facebook
Graham says It depends why you are wearing gaiters as well as the durability and fit of your overtrousers and the terrain you are crossing. When walking through undergrowth or scrambling over jagged rock or wearing crampons, wear gaiters on the outside of overtrousers to help protect them. To keep your feet dry, wear gaiters inside overtrousers so that rain cannot access the top of the gaiter. You’ll also be less sweaty around the lower legs if you wear gaiters inside overtrousers.
So for general walking where staying dry is the priority, wearing overtrousers over gaiters is a better option. This also means that when the sun comes out you can remove your overtrousers quickly and easily without having to remove your gaiters.
