The Mobile Mummy preformed as expected and as they claimed. I wasn't sure what the outside temperature was going to be, but I was excited to try out a new bag that was going to take 1lbs 6oz off my sleep system.


  • Accurate temperature rating
  • Light weight
  • Awesome design


  • Hood gets very warm when put on.

I wanted this bag from the moment I saw the video a local retailer sent to me in an email of upcoming products. I am a side sleeper and constantly move around while sleeping so this design caught my attention. It was tough waiting for Sierra designs to release information on it, but the wait was worth every minute.

When I finally saw the weight I knew I needed to pick one up. There was one advantage to waiting for it. I had already put away the money so when it became available I picked it up immediately.

I used it on a trip to Coyote Gulch in Escalante, Utah, just at the end of March 2014 and the temperature dropped well below freezing as evidenced by the ice on my tent fly when I awoke the first morning; I slept quite warm. This bag did everything that Sierra Designs claimed it would and the second night I slept even better.

The other thing I like about this bag is mine weighs 1lbs 11.4oz, which is less than what they claim. It's refreshing to actually find a product that works as well as the manufacturer claims. Only knocked it down a little for the hood, they could lighten the amount of down in the hood.
