The perfect rapid erect quick overnight or day shelter. The Cocoon Shelter is lightweight and simplistic to set up with its 2 rib, 2 break point construction. The 10000mm Hydrostatic Head means that it is extremely waterproof and the integrated 1/3 ground sheet means your bags and spare clothing can be kept off the ground. To turn this short session shelter into a fully bivvy during cold and wet days there is a seperately available winterkit. This consists of an overwrap that comes with a full ground sheet.
