I’ve got the exact snugpak sleeping bag,
i would say it was max a 2 season bag
i used it to tour denmark/sweden/norway in late summer early autumn and found it slightly uncomfortable
sorry I’ve just seen that some websites list it as a 2 season and some 2/3 season bag, so there we go 🙂
but didn’t find the quality that great on mine the stitching came undone(had to sew it back up) and also the compression sack it came with was terrible, the buckles broke on the first go,
fair play to snugpak though i contacted them and them sent me another stuffsack free of charge, but twas expecting a bit better,
i suppose for £40 it’s about right.
but would i recommend it,
probably not, I wish i had spent a bit more and got something else.
sorry I can’t recommend an alternative though 🙂
