Brand new for 2017, the synthetic fill polycotton sleeping bags of the Outwell Colosseum range – Single, Single XL and Double - have twin zips for maximising flexible use in varying temperatures. With a full-length zip on one side plus a halfway opening zip on the other, cosy insulation can be snuggled into or folded back to suit. Zip baffles with anti-snag running avoid cold spots whilst the embossed logo lining adds style.
