A cosy and roomy sleeping bag for two, that you can unzip halfway on warmer nights, or all the way to make a duvet.

The Outwell Colosseum range of synthetic fill polycotton sleeping bags have twin zips to let you choose your sleeping options for varying temperatures.

A full-length zip on one side, plus a halfway opening zip on the other, lets you snuggle into the insulation or fold it back to suit your style. Zip baffles with anti-snag running help to avoid cold spots from forming, to keep you comfy all round.
