NEMO Disco 15 £300

+ Comfort, freedom of movement, designed for side sleepers

- Fill power only 650, heavy, bulky, too roomy

This bag is very roomy. If you’re a side sleeper, tummy sleeper, night-time shuffler, or someone who hates the claustrophobic cocoon of a mummy-style bag, it’s a great option: restful, spacious and non-restrictive. For some campers this will enhance comfort greatly (I loved the roomy cut during a wild camp); for others the excess space and reduced thermal efficiency might be a dealbreaker. Other cons include the use of 650 fill power down rather than a higher grade, the rather bulky packed size, and the weight. But there are numerous pros too. The contoured, spoon-shaped cut provides extra space at the elbow and knees for easy re-positioning, the in-built Thermo Gills provide venting and breathability when required, and the waterproof footbox is well-protected against condensation. You also get a full-length two-way zipper, adjustable hood, integrated pillow sleeve, and – best of all – an extremely plush collar baffle that gives a lovely tucked-in sensation. The -4°C comfort rating is impressive (although potentially a tad over-optimistic, considering the spacious dimensions) and the generous 625g fill weight certainly gives the bag a thick, warm feel. Side sleepers form an orderly queue.

Verdict
