The Avid Revolve NG Bivvy Overwrap is designed to complement the 1-Person Revolve NG Bivvy, adding a dual-skin layer that boosts protection and improves insulation.

The overwrap features a roll-back front panel for an open-fronted setup and a two-way letterbox-style door for year-round use, plus two rod straps positioned on the front. - 10,000mm hydrostatic head Khaki fabric - Large rear mesh vent with zip access to the bivvy for optimal airflow - Main outer fabric: 100% polyester - Dimensions (cm): 145 x 260 x 290 (Bag size: 75 x 15 x 15) - Total weight: 3.3kg
