Cocoon Primaloft Overbag Sleeping Bag
Protect your mummy-shaped sleeping bag against external moisture and add an extra 11.5-Degrees C to its temperature rating with the COCOON Overbag. The roomy COCOON Overbag has an ultralight Ripstop Nylon shell and two layers of Primaloft Sport Insulation over the top and sides. (The bottom remains uninsulated to minimize packing size and weight.) Primaloft is naturally water repellent and, therefore, a great choice for an overbag. The COCOON Overbag will turn a lightweight bag into a 4 season bag, a winter bag into an expedition bag and can be used as a roomy summer sleeping bag when combined with a sleeping pad.
