Warmth that holds when the ground turns damp

The synthetic hollow-fibre fill keeps trapping air even when the night gets damp, which is the sensible choice for wet British bivouacs where down would clump and quit. The maker rates the bag down to -20°C. Treat that as the survival end rather than the number you sleep comfortably at, sit a season or two warmer, and add a liner when the cold really bites. The 170T polyester runs inside and out, so it shrugs off abrasion and repeated field use.

One bag, several jobs

Undo the full-length zip and the bag opens flat into a blanket or a groundsheet, so it earns its place beyond sleeping. The envelope cut gives you room to shift about, and the drawcord hood seals warmth in around your head. Pick from seven fill weights, from a light 0.7kg for milder nights up to a heavy 4kg for the cold end, in three camo finishes.
