In pursuit of enhanced winter safety, Klim has engineered the Rift Jacket to offer protection, warmth and flotation for the most extreme trail conditions. Ascent Float Technology (AFT) is a flexible, breathable closed cell foam that we integrated in specially mapped channels that offers life-saving buoyancy benefits without compromising mobility or comfort. AFT foam does not absorb water and provides significant insulating properties for warmth when paired with conventional Thinsulate insulation. The Rift Jacket is a comprehensive trail jacket for riders looking to maximize every winter riding experience. The Rift Jacket does not need pairing with flotation bibs to offer riders flotation benefits.
