The Black Diamond Clipwire Ski Leash is way, way, way cheaper than a new ski if you should blow out of your bindings. For that matter, remembering to put it on is way easier than skiing on one foot trying to catch up to the other ski. It’s easy to get on and off, durable to the point of absurdity and leashes are required at most resorts. These leashes are factory seconds, meaning they work perfectly, but may have some cosmetic imperfections. That just means you save some cash for cold ones after your tour.
