I generally sleep in a hammock. Never much below 25F/-4C. I've looked at a lot of bags, but theres a few hundred to choose from. I'm looking for something under 1.5lbs/681g. Obviously the lighter the better. I've looked a lot at feathered friends and Mont-bell, but from all my experience with sleeping bags the rating on the bag is more a "you-wont-die-at-this-temperature" than a "you'll-be-comfortable-at-this-temperature." (Keep in mind that I've never really spent the money on a quality bag.) I've done plenty of reading and comparing this bag to that bag, i just cant come to any sort of good conclusion about which bag is going to perform well.
