A Note from OWL’s founder:

The Miserable Camping Moment that Led to the Evolution SlumberSac™

If you’ve ever camped in the backyard, pitched a tent at a campground, or hiked that trail, into the wild—you know that moment. The stars above, the crisp air, the stillness of the world around you. These are the moments that sparked my true love of the outdoors.

Over the years, outdoor gear evolved in incredible ways—lighter packs, smarter fabrics, better tents. But one essential piece never changed: the sleeping bag. It hasn’t fundamentally changed in almost 100 years—restrictive, hard to move in, and even harder to get out of when nature inevitably calls.

That realization became the starting point. I asked a simple question: What if the sleeping bag had evolved, too?

The Turning Point

The idea hit—literally—on a cold spring night in 2024. After fighting a jammed zipper at 3 a.m., freezing and desperate to get outside, I realized that my “modern” sleeping bag had failed to keep up with today’s adventurers. The world had moved on, but outdoor sleep still hadn’t.

That night, a new vision was born—to create a sleep system that moves with you, and for you, not against you. Something functional, ergonomic, and freeing—without sacrificing your warmth or comfort.

The Evolution Begins

From sketches and prototypes to field testing in Colorado’s backcountry, that idea became the OWL Evolution SlumberSac™ Series—the first true reinvention of the sleeping bag.

Designed with a footbox that flips open for walking, centered zippers for easy entry and exit, and integrated sleeves for full mobility, the SlumberSac redefines what it means to rest outdoors. It’s not just a sleeping bag—it’s a it’s a complete shift in how we experience outdoor sleep. Lightweight, weather-resistant, and built for movement, it lets you explore, rest, and reconnect with nature—without compromise.
