it'll be aight gary,
get back out there in a couple weeks, you'll have fun.
you can't go wrong with kelty as a basic sleepin sack. i had one for a couple of years til i got real serious abt backpacking. (5deg synth mummy bag. called cayenne, looked like a big red pepper, ha ha)
a couple years ago i bit the bullet and bought a real nice down bag. i looked for months and tried everything before i made a decision. it came down to two options for me: feathered friends or western mountaineering. (
www.featheredfriends.com &
www.westernmountaineering.com)
it was between the rock wren ii (winter) (ff) and the ultralite (wm). i think that's what the wm bag was called, i can't remember exactly.
anyways, i was lookin for a bag in the 10-20 deg range (i sleep hot...). i also use a liner the majority of the time, so that drops it another 5. the rock wren is an awesome design with leg and arm holes so you can walk around in it. they were both crazy light and crazy compactible.
i ended up gettin the ultralite (on sale, yeahyo!). in the stuff sack it weighs in at 1 lb 12 oz (a good 2.75 lbs less than the trusty kelty). it can compress down to about the size of a softball (that is just crazy, really).
both companies offer various fabric options (epic, nexTEC, etc) and they both have very good downproofing processes. the wm site has awesome write-ups on their techniques. i went with the basic ultralight nylon stuff (weighed in a .7 oz a yard

).
anyways, sorry to rant, but i love my bag. so nice, light, downproof, plus it looks really cool, ha ha. (bright blue and black).
also, i won't ever go back to synthetic stuff (even though the newer polarguard is nice). just not as near compressible, weighs too much, and if you're used to camping, you should be able to to prevent you bag from gettin wet, plain and simple. (both ff & wm give you a waterproof urethane stuff sack).
