Snowboard leashes and locks are important safety features that have been incorporated into the sport of snowboarding. A leash is basically strap that attaches the snowboard to the rider through the rider's leg, boots or bindings. It is designed to keep the board and the rider together to help reduce the risk of runaway snowboards which could cause injury to others on the slope. Locks, on the other hand, are used to secure your snowboard to anything if you happen to have to leave it for a while. There are a variety of snowboard leashes available and many snowboard leashes now include locks.
