I'm new to the backpacking world, and plan on mainly weekend trips only for now. I already have a good lightweight tent and a fairly small pack (44 liters). I'm looking for something that compresses down small, but rated for 20 to 30 degrees. I don't want cheap crap, but simply can't justify spending over 150-200 bucks. I don't want to be "that guy" who buys all the best gear before he knows what he's doing. I'm an experienced camper, but have never had to pack my sleeping bag on my back before. My current sleeping bag doesn't compress enough to leave room for anything else in the pack. I'd rather not strap it to the pack (I'm already doing that with my sleeping pad and tent poles). I'm reluctant to shop for a bigger pack because the one I have is new and I love it (Osprey Talon 44 - bought for ski trips).
