Big Agnes

THE MOTHER OF ALL COMFORT

At our core, we want to inspire you to get outside and find the same appreciation for the backcountry we have.

Big Agnes started over 20 years ago with the goal to build better gear to get people out camping. It was a simple idea rooted in providing comfort to brave souls sleeping in the backcountry and keeping them on their sleeping pad. Who could have imagined two decades later we would be making award-winning gear, changing the sustainability game with solution-dyed tent fabrics, and helping you haul all that gear in backpacks?

Based in a ski town in northwestern Colorado, our backyard is an outdoor paradise, and our testing grounds are within sight of our office. The Continental Divide Trail is home to some of our favorite trails for skiing, hiking, and mountain biking; the Mount Zirkel Wilderness beckons us with its high alpine summits. The Yampa River flows a stone’s throw from our office; and on most lunch hours the office is quiet enough to hear a pin drop while we’re out finding fresh air or fresh tracks of one kind or another.

Being surrounded by outdoor recreation makes us appreciate our environment every time we get outside. We strive to incorporate practices from design ideation to end-of-life solutions committed to protecting the outdoors. Our social impact is greater than the gear we manufacture. We partner with over 20 organizations that help protect our public lands, support sustainable practices, and lead in equality and inclusivity.

Our urge to sleep under the stars and breathe fresh moun­tain air is what continually drives us and keeps us motivated. In the end, the bluebird summits and nights spent listening to raging creeks or even highway noise have made the journey awesome, and truth be told, we wouldn't want it any other way.
