My go-to for any trip where weight isn't the largest concern.


  • Soooo comfortable
  • Light for its size
  • Freedom of movement


  • Pricey for car campers
  • Not as compressible as quilt or mummy

I've been a mummy bag user for decades but it was time for a change. I use this mostly on weekend trips, car camping, and disaster response. I've spent about 100 nights in this bag and there is virtually no wear at all. Most of these nights are on a Red Cross cot while deployed with Team Rubicon.

Sleeping temp and comfort is extremely subjective, but I have found this comfortable without a base layer to about 40-45°. For reference I tend to be a warm sleeper.  

I am in love with this design. The footbox has an opening that allows you to poke your feet out to cool off and while there are no mechanical fasteners there is no draft from this.  

The opening is large enough to get in and out with ease and the quilt portion is pretty huge allowing you to tuck it in to prevent drafts. I've never had an unwanted draft.  

At first the hand pockets seemed silly, but I use them without thinking about it in my sleep as I move from back to side sleeping.  

These bags will accept a 20" or 25" pad in its sleeve by simple snaps for adjustment. All my pads fit great. My thickest is 2.5" and there is space for a little more. The pad is a must as there is no insulation on the bottom.

The head space allows ample room for a nice thick pillow.  

Weight is great considering its size, still lighter than many syn mummy bags. Compression is very good and acceptable for backpacking. I find sleep comfort vital to enjoy my trips. When weight or size is vital I use just a pad and down quilt or just my woobie.  

Give this style of bag a try. I think you will love it! I liked this so much I bought the same thing in the double size for my wife and I to share.
