I agree Western Mountaineering bags are the best I know of. Its the best I have tried. My gear has changed a lot since I first backpacked in for elk about 9 years ago. I would recommend taking a 4-season tent just in case. It could be t-shirt weather or you could be tracking in snow, and occasionally you get to do both in the same day. Beating snow off your tent all night to keep it from collapsing is not the most fun. The 4-season tents I have used you sometimes don't even know it is snowing until you hear it slide off the tent. They do tend to be heavier. A two man Sierra Designs I used in the past weighs around 11 lbs. I currently use a Hilleberg Soulo, which is about 5.5 lbs including footprint. This is the best tent I have ever used. Expensive, but I would have saved money if I had just started out with this one. Several options to save weight, but being able to set up in the rain without getting the inside wet is a big plus.
