I'll sell you mine. I have a like new Western Mountaineering MityLite. I used it about 3 times wearing clean clothes in a tent.

It is rated at 40F and weighs 26 oz on my postage scale. I've never liked tight bags for summer sleeping, so I bought this bag for it's generous semi-rectangular cut. It fully unzips so you can use it as a quilt, too. Retail is $270, but I'll sell it for $170 with WM stuff sack and cotton storage sack. If you're interested, I'll send you pictures. david_eastwick@hotmail.com
