Neoprene is a family of synthetic rubbers that are produced by polymerization of chloroprene. It is usually covered on both sides with fabric (nylon or lycra), protecting the surface making it less prone to damage. Neoprene was one of the first synthetic rubbers to be developed and has been incorporated into numerous products popular in daily life, from wetsuits to protective gear. We use neoprene hip belts on our Ski Backpacks Freerider and Descentor allowing a snug fit. Furthermore, neoprene is well suited for its flexibility, shock-protection applications and provides excellent insulation against cold, used in our Neo belts, camera case and insulation tube.
