Sleep System / Sleeping Bag

[BeardyMan]

Czech one? I used the Czech army bed roll last friday, worked well, nice and warm. Add a couple of thick wool blankets in there an you're good to go.

Dead of winter, I'd be using my Tennier Industries US army modular sleep system.
Good down to -28 I think, and you can combine the bag with the ECWS clothing to bring figure to -50 (for 4 hours, you need the coat & trousers & underlayer - heavy stuff)

Best sleeping bag I've ever used by far. Big an bulky, but not as big as the UK one.
