If you're serious about wild camping and backpacking. you can't beat this sleeping bag. High quality, 900 fill power goose down delivers an EN/ISO comfort rating of 0°C, despite weighing just 580g-so the overall warmth-to-weight ratio is top-notch. This is aided by the zoned design, with 70% of insulation placed on the top and sides (where you need it most) and 30% on the underside, while the box baffled construction further boosts loft and minimizes cold spots.
VERDICT
An excellent mummy-style sleeping bag and delivered at a superb weight.
