The Black Diamond Vario Speed Harness' one-size-fits-all design allows your entire family or a whole climbing class to use it. A favorite of guides and climbing instructors, this Black Diamond harness includes fully adjustable waist and leg loops equipped with speed buckles for minimal hassle and increased safety to get climbers where they want to be-on the wall! The pre-threaded buckles on the Vario Speed Harness eliminate the need to double back, so a beginning climber will never be in danger of forgetting, and the single, durable tie-in point keeps you or your friends from tying in incorrectly.
