Fitment: Fits for Cruisers, Standards, Sports Touring, Adventure Touring and Harleys.Cushion Material: Diving elastic fabric feels delicate and soft, greatly improves the feel of the cushion and the recovery of crease. It's of high rebound, no deformation and can be repeatedly washed. And TPU fabric has outstanding load-bearing capacity, impact resistance as well as shock absorption.Air Convection Technology: When the airbag receives the squeeze, the gas flows to each other, producing a uniformly pressurized "anti-gravity" effect.This process can buffer the vertical pressure of more than 1/3 of the body weight, greatly reducing the load and pressure of the tail vertebra.Breathable & Comfortable: With shallow groove design, you will stay cool even you have been sedentary. The 3D airbag gap can achieve excellent ventilation effect, so the cushion is comfortable and not sticky.
