Awesome ultralight bag

Ranked #335 - 55 to 30 Degree Down Bags
June 17, 2009
I have the previous generation of the product, as well as the new (2009) model. I bought the new one for the new, full length, two way zipper. They otherwise seem functionally the same. They are extremely lightweight, compact, and durable. I have used it on multiple occasions with temperatures in the 28-32 degree range (the 2007 model), and have generally been quite comfortable with a light base layer and thermal cap, though I think this is the lower limit of the bag. I was in it into the mid 20's once (it got alot colder than forecast) and was a little too chilly despite stuffing some of the clothes I had into the bag with me for extra insulation. The new full lenth, 2-way zipper makes a great bag even more flexible, extending the comfort range into very warm temps, since you can now "hang out a leg" or unzip all the way down. The only negative I can find is the price is a little high, but I think it's worth every penny, and highly recommend it!
