The Nash Extreme Canopy converts the Titan T1 bivvy into a spacious two compartment shelter. The canopy dramatically extends your usable space by over 70% and increases the headroom, giving you extra protected room for storing your tackle, or day to day tasks such as tying rigs, preparing bait and water watching. This simple but brilliant canopy allows you to divide the bivvy's areas into a wet environment of bait, tackle, nets, waders, etc and a dry sleep area.
