Following closely in the footsteps of Inspire Bivvys. The Avenger range of bivvys share a lot of the same design features. By using a slightly different specification of materials makes them very affordable without losing any of their functionality. The 2-rib construction resulted in lightweight and easy to assemble shelter. Both versions feature a roll up peak section, perfect for those quick sessions in fair weather, where extended protection from the peak is not required. The Pro-Vent system has been used throughout – a large rear vent, and 2 added side vents, provide the very best 360-degree ventilation. This maximises air exchange, reduces condensation and increases observation as well as keeping you cooler during the warmer months. The heavy-duty ground sheet helps prevent bug and water ingress and is easily secured in place using Velcro. The Avenger Bivvys use our 210D (Double coated) lightweight, extremely durable and waterproof to 10,000mm. The front door is fitted with a Mozzy meshed window and dual zipped doors, allowing letter box-style opening and greater protection from the elements. The Condenser Wrap supplied with the 1 Man Bivvy. Both offer a hydrostatic head of 10.000mm using the 210D (Double coated) fabric. When combined it provides a much higher efficiency rating by allowing the internal Bivvy capsule to breath affectively. As the transition of air exchange is greatly reduced. This provides a much slower and progressive air exchange rate. Which dramatically Insolates the internal air against the external air temperature creating a superior isolation barrier. This process dramatically reduces moisture and condensation build.
