Tom Rottmannwrote a review of Western Mountaineering MegaLite Sleeping Bag: 30 Degree Down on October 8, 2009
For warmer weather and extended hikes, there is not a better bag. Used this in the warm weather portions of my 06 and 08 AT hikes and it never let me down. Very light and even as you drop below the rating on those colder nights, a simple base layer and socks kept me warm. I switched from using the Marmot Pounder simply because I experienced an internal condensation issue with the pounder (although I admit I was pushing the pounder past its design). The price tag is hefty with this bag so you should really be needing the warmth/weight ratio to justify the price. I have used this bag for no less then 9 months of hard use on shelter floors and it is still holding up well. For me, it was well worth the price tag (I think I paid around $225 in 06) It will be my bag of choice after Damascus in my upcomming 2010 AT hike.
