I just picked up a pair of 686 pants. These things look nice but are a little too advanced for my liking. So they consist of an insulated liner, gaiter, and the outer shell, in this order. Given the gaiters have a metal hook, I understand they go over the boot (although oddly I have never done it this way - always went inside the boot). What should I do with the insulated liner? It has plastic buttons so stuffing it inside the boot might be painful.. Anyone?
