Just seeking a bit of advice here - I'm after a lightwt 4 season sleeping bag, pretty much to survive the worst the UK can throw down. I'm pretty small (5'7.5") and feel the cold so am looking for a snug fit rather than a "roomy" bag.So far the following seem to be the best bet:PHD Minim 600Rab Alpine 600 - Alpine rather that Neutrino due to the Pertex lining?Appreciate any advice - or other options - thanksRich
