I've been thinking about getting a synthetic modular sleep system so that I can get out a bit more and in a wider range of weathers. I quite like the older USGI MSS in woodland camouflage - the one with the bivi bag, patrol bag and intermediate bag. The downsides of that one seems to be it is very bulky and possibly quite expensive to get here in the UK. So I've been looking at two other alternatives which are a bit easier to get hold of and seem likely to be a bit less bulky: * Snugpak Special Forces 1 + 2 + expansion panel, * Carinthia Tropen + Defense 4. I don't have a goretex bivi bag at the moment but was thinking of just getting the UK army one to begin with. Does anybody have any thoughts, comments or suggestions to offer? Cheers, Windscale.
