An overwrap for the Professional Bivvy. This overwrap is manufactured from the same material as the bivvy. The three full sized windows have three layers with 25 mm velcro on the front and two layers with 50 mm velcro on the rear that follow the shape and contour of the bivvy windows. There are 4 velcro rod holders and heavy duty zips with Easy Grip tags supplied as standard. This overwrap helps to eliminates condensation, increases thermal comfort and ensures the bivvy is even more stable in extreme wind.
