should fit your bill. it's a 5* bag, but they don't fib on their numbers. if you are a cold sleeper this might not work, but it's a bag i'd consider. you can find them lightly used on ebay or gear forums in the mid-$300 range.

thanks all for the advice.

I went with the marmot lithium for the following reasons:
• many ppl had good stuff to say about other brands but in my research no one says anything bad about this bag
• I was able to get it at rei which has a 100% refund policy (there are probably pros and cons to this in other threads, but for me it's a pro as im unable to invest in this type of gear easily, and the freedom to test is valuable)

thanks for your help, i'll let you know how it goes!

p.s. i always bring a second set of long johns etc; i alternate and change when i get camp set up, putting on a fresh pair of dry clothes.

Both fine reasons. IMNSHO, of the big outdoor manufacturers, Marmot makes the best sleeping bags.

My experience has been 180 degrees opposite from yours, provided that my bag was cut full enough to accommodate heavy clothing. In a bag that is too small, wearing all your clothing can be restrictive, and you don't get the full benefit of the extra insulation. However, in a bag that is more fully cut, I've found that I sleep much much warmer with all of my clothing on. Whatever benefits I might gain from my body and bag "interacting" seem to be small compared with the benefits of the extra insulation provided by my warm clothing. (plus, my clothes tend to dry out overnight, which is better than having to put on frozen damp clothes the next morning.)

That's my experience. I'm not saying you're wrong, just that your solutions are not universal. However, I'd guess that most folks who do a lot of alpine climbing in cold places factor in their clothing as part of their sleeping system.
