These forums have been so helpful with suggestions for a backpack and sleeping pad I figured I would go for the trifecta and ask for sleeping bag suggestions. I have only ever owned one sleeping bag and I like it but it is far too bulky for backpacking.

1) Needs to be backpacking friendly in terms of size and weight.
2) I'm 6'3" so it needs to be a long bag.
3) Can't be made with down as I am allergic.
4) Three season bag, not all season. I have camped once in freezing temperatures and have no desire to ever do so again (and I'm not thru-hiking).

Thanks!
