Yeah, I haven't used my zero degree bag in years although my cold sleeper wife has a couple of times. I've also learned the trick of wearing layers to bed, so I've greatly extended the operational temperature range of my 32F bag. I love my 32F bag because it packs small and is pretty darned light (about 1.25 lbs). I also recently bought a Yama Mountain Gear tent, a Cirriform Double Wall, 1.25 lbs. They have an even lighter single wall version, but a double wall came up on one of the various gear swap forums on Facebook for a good price, so I pounced on it. Temps were down to low 20's, possibly even high teens when last I was out, but I did OK.
1.25 lbs - Cirriform DW Tent (one person)
1.25 lbs - Western Mountaineering Summerlite 32 F sleeping bag.
0.50 lbs - Neoair 3/4 length pad.
2.00 lbs - Gossamer Gear Mariposa backpack.
5.00 lbs - total for the "big three" (sleep set up, shelter, and backpack).
