Why We Made This
“Building a system is not something you do as much it’s a way you think.”
- John Barklow, SITKA Big Game Product Manager
We took experience and insights designing clothing systems and applied that knowledge to the sleeping bag, turning something you typically use just for sleep into a multifunctional tool for backcountry use.

Improvements I think could be made in offering this in some sort of camo. Black is the worst color for blending in especially if using for a glassing or from a tree stand.
Additionally 30 deg isn’t bad when used with clothes under bag but a slightly lower rating could improve its versatility.
Camo offering being number one Improvement.
Barklow and the whole Sitka team have created a fantastic system based solution with this bag. It’s light, it’s compressible, it’s synthetic (bombproof performance), and it’s extremely versatile for a wide range of temps when used as suggested as part of the system. I’ll be ordering another as my wife stole my first one.
Its genius and I'm looking for a local dealer!! I have a WW2 German "sleeved" bag that zips open 3/4 pant leg and has tie strap to make a seat, Can't wait to partner it with your 'wearable' bag.
The first reviewer doesn’t ‘get it’! This bag is meant to function with your clothing system so you don’t have to have a -(30) degree bag that is heavy… you use the puffy to augment the bag since you’ll need your puffy as an integral part of your system — why don’t people pay attention to the functionality and design?!
Badass bag, but a 30 degree bag doesn't cut it for Alaska’s back country, hope something warmer comes out very soon

The Darkroom: Built with Purpose
If you walk into our design room, you'll hear our designers throwing around terms like "fit," "features," and "purpose built." But what does that even mean?

I tested this sleeping bag out this weekend. I slept outside under the stars and never once felt cold as the temperature dropped to a breezy 40°F. In fact, I was a little too warm at first. The zipper down the middle and the zippers for arms is an absolutely genius design. I was able to reach for my water or headlamp without having to open up the sleeping bag and let out all the heat. Whenever I needed to get up in the middle of the night to answer nature's call, I simply opened up the bottom, hooked the bottom up, and walked out to do my business. The next morning I spent the greater part of 3 hours walking around the cold campsite with my sleeping bag while everyone else was bundled up shivering. I was skeptical at first, but this sleeping bag proved its worth very quickly.
Love it!!!! It works so well with my clothes and kept me warm all night in -22°F weather.
This is the most important change to sleep systems in the last 10 years. Watch as everyone else starts to copy Sitka's brillance. Maybe a future down version please. I'd love to help test it.
I agree with the first review. Not all of us like to crawl into bed every night in our sweaty clothes. Some nights OK but not every night. A bit more fluff would be good.
