MOUNTAIN EQUIPMENT FIRELITE £500

Securing an EN/ISO comfort rating of -2˚C but weighing in at just 770g, the Firelite is warmer than many bags over 1kg. This is achieved through a healthy 469g portion of 800 fill power goose down, which feels reassuringly thick and should perform to the quoted temperature ratings. You also get an ultralight Plasma 10-denier shell, a full-length zipper, and an adjustable hood. VERDICT A reliable sleeping bag with premium features and insulation – but it’s rather pricey.
