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.

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
