Designed in collaboration with 6x world champion Bruna Kajiya, the Gem BK Waist Harness blends signature style with proven performance. Updated this season with a new glitter plate that adds a distinctive signature finish. Built using the same Roven Composite found in the Majestic, the harness offers a supportive feel in a sleek, minimal shape that stays comfortable through long sessions. Soft neoprene edges and Fix Foam cushioning help reduce pressure points, while the Battle Belt system and Flexcovers with an integrated safety knife pocket keep everything secure when riding powered. A signature harness shaped by years at the top of the sport.

The Bionic Core Frame is stiff in the horizontal direction, but is still able to twist and follow your body. The carbon composite enhances the stiffness for the most extreme conditions.

This foam is moulded to adjust perfectly to your lower body and give maximum comfort while riding.

Soft neoprene prevents rash while riding on bare skin against the edges of the harness, and also creates a closer more comfortable fit.

Once you've adjusted your webbing, get the straps out of your way with the new Flexcovers. These Flexcovers have got a locking mechanism to make sure the webbing stays tucked away.

The flexcover is designed to store your excessive webbing, which would otherwise flap about during your session. Behind the cover there is a hidden knife pocket to get you out of any gnarly situation.

Safety first! With the adaptive leash eye you can attach your safety leash to the front webbing of your harness, which is the safest position since it is always within reach when things go south.
