A Note from OWL’s founder:
The Miserable Camping Moments that Led to the Evolution SlumberSac™

Think back to your last camping trip—backcountry, car camping, even the backyard with kids. At some point, you had to get up in the middle of the night to pee. It’s as predictable as burnt marshmallows—and about as fun.

We’ve all done it: half-asleep, wrestling with a stubborn zipper, fumbling for freezing clothes, trying to step into boots like a baby giraffe. Then the dreaded return—boots off, layers peeled, and the awkward wriggle back into a now-icy bag. Sometimes you stash clothes inside to keep them warm, only to wake your tent-mate while struggling to dress like a drunk octopus. Add a stuck zipper, torn fabric, or a dash of claustrophobia, and it’s the camping version of Groundhog Day.

One restless night in the Spring of 2024, after my third trip out to answer yet another “call” from Mother Nature—and trying not to wake my partner and dog—I hit my breaking point. I needed my arms free, I needed mobility, and I desperately needed a way to stay warm without the constant in-and-out chaos. That night, necessity sparked invention.

Enter the OWL Evolution SlumberSac™ Series—a patent-pending, ergonomic sleep system designed for warmth, mobility, and freedom. With a footbox that flips up for walking, intuitive zippers, and true adaptability, it transforms camping from a series of midnight miseries into restful, cozy nights.

This may just be the last sleep system you’ll ever need.
And honestly—you deserve the upgrade.

So, are you ready to stop fighting your gear and finally get the rest you need in the wild? Then it’s time to think inside the bag.
