The Haglöfs Slumber 3S is a roomy, comfy, mummy-shaped 3-season synthetic sleeping bag. The full-length two-way zip has a double baffle to help eliminate heat loss, and the large shoulder baffle further seals heat inside the bag. The hood is very protective and well-shaped while the hood and shoulder baffle drawcords are a mix of tape and bungee cord so you can tell them apart at night. The fabric is pleasant against the skin and the bag quickly feels warm inside. The outer fabric has a very good DWR coating for shedding water and it will be tough, being made of polyamide. The foot box is well-shaped and roomy, and there’s a small pocket for keeping essentials to hand. But the zip snags quite often. More importantly it’s a -11 deg C bag, so it is warmer, heavier and bulkier than it needs to be. The £75 Slumber 2S is a -5 bag and a better option, but that still weighs 1700g, so it’s still quite heavy.

Verdict: The Haglöfs Slumber 3S is warm and comfortable, but the temperature rating of this synthetic sleeping bag is warmer than it needs to be for a 3-season bag, which adds to the weight when packing.
