Evolution Slumber Sac Xtreme
TBA/Coming Soon!
The Evolution SlumberSac™ Xtreme will advance the cutting edge OWL flagship design with a detachable lower section, allowing it to convert into a fully wearable insulated jacket with a separate bottom half sleep system, which will give an added benefit of increased space inside your pack. Retaining the walkable bottom design of the original Evolution SlumberSac, the Xtreme delivers exceptional versatility, reduced pack weight, and unrestricted mobility without sacrificing warmth or comfort. It uses the same durable 10 Denier Ripstop Nylon and ClimaShield insulation as its predecessor. The footbox unzips and opens, and magnetic catches allow the front and back panels to flip up so you can easily put on your personal footwear so you can move around. Ideal for adventurers who demand dependable warmth, adaptive performance, and true freedom of movement.
