PATAGONIA 850 DOWN 19°F/-7°C £500

We tested this bag back in a very chilly early spring last year, and we still think wistfully about the nights we spent in it. Being cocooned inside it is pure luxury, with high levels of warmth and comfort. The mummy fit is surprisingly roomy given the tapered appearance. The unusual centre zip is an excellent design for side sleepers as it doesn’t seem to get twisted, no matter how much you wriggle around.

VERDICT Possibly the most comfortable 3-season sleeping bag around, with a centre zip design that is perfect for side sleepers.
