Better Sleep Systems Start With Better Understanding

At Gryphon Gear, we believe better nights in the backcountry begin with better design. Every quilt and sleeping bag combines decades of mountain experience, scientific engineering, and handcrafted construction to help you sleep warmer, carry lighter, and adventure farther.

Three Things Make Every Gryphon Gear Product

Every Gryphon Gear sleep system is built on three foundations: real-world experience, engineering, and craftsmanship. Together, they create gear that's designed to perform when it matters most.

Technical Expertise

Every design decision, from differential construction and custom sizing to temperature ratings and baffle design, is based on understanding how insulation, body heat, moisture, and materials work together. 

Experience in the Mountains

Hundreds of nights in the backcountry teach you what product specs never can. Real-world experience reveals what actually keeps people warm, where traditional designs fall short, and what matters when every ounce counts.

Craftsmanship

A great design is only as good as the person building it. Every Gryphon Gear quilt and sleeping bag is individually cut, sewn, filled, and finished by hand. That attention to detail allows us to maintain the quality, consistency, and performance our customers rely on in the backcountry.

Gary which is your favorite photo of yourself?

"I had just finished my PhD and was a research scientist at NASA. I had bought a new nylon tent and backpack, but with the application of a little “science”, I knew that I could do better.  I hand made my first down jacket, down pants a shell parka and a winter bag. After seeing my gear, my mountaineering club friends all wanted me to custom make gear for them. And so I did - Gryphon Gear® was born!"

From a Passion Project to Trusted Backcountry Gear

What started as custom gear for friends has grown into Gryphon Gear today. A company dedicated to building premium ultralight quilts and sleeping bags for backpackers who refuse to compromise.

While the products have evolved over the years, the philosophy hasn't. Every sleep system is still designed around the individual, built by hand, and tested against the same standards Gary expected from his own gear decades ago.

Why We Build Made-to-Order

Mass production works well for many products, but a sleep system isn't one of them.

No two backpackers are the same. Height, shoulder width, sleeping position, metabolism, and trip conditions all influence how a quilt or sleeping bag performs.

That's why every Gryphon Gear sleep system is built specifically for its owner. Instead of asking you to fit into predetermined sizes, we build your gear around you.

The result is:

• A more efficient fit
• Better thermal performance
• Less unnecessary weight
• A sleep system designed for the adventures ahead
