After wanting this bag for years, I finally got it last Christmas to much anticipation. Unfortunately, I returned it due to several factors. First, the elastic spiral baffles did not cinch to the degree that was shown in the pictures. Mine looked overstretched. Because of this, the bag as very loose leaving many cold areas. Even using a hot Nalgene bottle to help warm me in my bag wasn't sufficient. The last straw was the customer support at MontBell. Although their call center was in the USA, the company was very impersonal and not very helpful. This is not what I have found with stateside gear companies. I do have to say that Backcountry has been WONDERFUL though this whole experience! They now have a lifetime customer!
