[Quote from the website] The "Ski Trainer" from Lucky Bums in America is a sports harness with a leash that is convenient for helping children quickly improve their skiing. The backpack that holds the leash has a grip, so you can firmly support your child when getting on and off the lift. By attaching the leash sideways, it can also be used for snowboarding.
