Thanks for the reply, Alan. Unfortunately the Double Black Diamond looks unnecessarily wide. It’s intended for my girlfriend who’s 1.7m (5.577ft) tall but very slim. Narrower but a tiny bit warmer would be great. Doesn’t even have to be down (as long as it’s light) and doesn’t have to be dirt cheap. Otherwise we might have to go for the HG Economy Burrow 5°C (40°F) and just hope that it’s not too warm. There are tons of sleeping bags in this temperature range but I don’t want to go with something like the Millet Baikal 750 ( … ple-1.html ) because it’s a sleeping bag and weighs twice as much.
