Our Story

Keith began this journey as a kid in the rural Uintah Basin region of Eastern Utah. Several of his earliest memories were camping up high in the mountains to the North where he and his cousins slept together in a giant makeshift bed made out of his grandma's quilts.

While it was fun to chat and watch the stars at night, some nights were too cold to fall asleep. After Keith had grown into a young teenager, his grandma taught him a way to fold two quilts together into a bedroll sleeping bag. It worked well, so well that Keith never found a sleeping bag that did better for many, many years.

In 2009, Keith met Jim Phillips and learned about a unique foam sleeping bag. The foam stayed warm even when wet and dried itself with regular use, but the designs for the bag itself retained a lot of design flaws from traditional sleeping bags.

Keith spent the next decade developing and personally testing his own sleeping bag prototypes using Jim's foam technology. The pursuit of creating the ultimate sleeping bag became an obsession. Starting in the early 2020's, Keith began inviting others to test out his sleeping bags too. They worked well, but were too complex.

At the beginning of 2023, Keith decided to reimagine his system from scratch, throwing out all of the issues related to traditional sleeping bag design while seeking to optimize the benefits of the unique foam technology.

The result, was the Cocoon.

The Cocoon's unique design makes it durable and easy to use, allowing a person to sleep comfortably in any position or orientation. The full-length opening utilizes magnets to minimize the risk of damage while providing a secure seal when closed. The materials are free of any cotton, down, holofil, wool, spandex, Gor-Tex™, or anything else that might compromise the effectiveness of the foam's special Moisture Vapor Transfer system.

Shortly thereafter, Keith founded K3Core and began recruiting others to help him bring his sleeping revolution to market. The K3Core team is constantly innovating new products and improvements to compliment the ultimate sleeping system.
