In pursuit of enhanced winter safety, we've engineered the Rift Jacket to offer floatation assistance, protection and comfort in the extreme conditions trail riders face. This is a redesign of the first float assist GORE-TEX jacket in the world and it doesn't need to be used with floatation bibs to work properly. Ascent Float System (AFS) is a flexible, breathable closed cell foam that we integrated in specially mapped channels that offer floatation benefits without compromising mobility and comfort. AFS foam doesn't absorb water and provides significant insulating properties for warmth on top of the standard insulation. The Rift Jacket is a comprehensive trail snowmobile jacket for riders looking to maximize every winter riding experience.
