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!

I actually bought both the 8.5 and 10 oz END Stumptown trailrunning shoes to try, and am putting this review under each shoe. They are cut VERY differently. The 10oz is MUCH wider across the forefoot than the 8.5 oz. It feels better constructed than the lighter shoe. It has a removeable footbed, vs a glued in footbed on the 8.5oz shoe. Both are quite comfortable. The lighter shoe is not really supportive enough to be a trail running shoe, IMO, but if fine as a lightweight casual shoe. The 10oz is definitely the better shoe as an actual running shoe.
