Climbin skin help

Buy the 140mm, dont go with the waist of the ski, but with the tip waist and trim them. So if you tip is like 145mm buy a 140mm skins and trim it

Yeah Banane. has it right with skin sizing, though I will say when you have wider skis like that, you already have quite a lot of skin surface area. There is plenty to grip the snow, especially when it's softer, so you don't really need wall to wall coverage. Some skin companies have actually removed a strip of "skin" from the center of their wider skins to reduce weight. The uphill grip is basically from your toes to the back of the ski. I got 125mm skins for my bentchetlers(144.5/123/136.5) because I don't really plan on skinning on any gnarly steep ice or anything like that. You can typically get away without the whole tip being covered and save a bit of money on narrower skins.

make sure that whatever size skin you buy that you trim it inside your edges a little bit. you want to have some edge clear of the skin to make it so you can side step up when you need to.
