Daniel Neilson braves the cold to test some of the warmest sleeping bags on the market. On test Kelty Cocomell Down 0 sleeping bag

The ‘0’ in the name is Fahrenheit, which is -18C. It’s one of the cheaper bags here reflected in the relatively low down fill power. As a result it’s the heaviest down bag here. It’s a little odd in that the hood zips off and it opens all the way around so you can use it as a blanket. One problem with this is that I couldn’t get a great fit around the hood and there’re more cold spots along the zip. The zip baffle wasn’t wide either. I wouldn’t use it to -18C, but to be fair, Kelty call it an ‘Autumn’ bag.
