Gryphon Gear

Built by a NASA Scientist.

50 Years of Obsessing Over Warmth

"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!"

- Dr. Gary Benninger

At Gryphon Gear, there is no mass production or one-size-fits-all approach.  Every product is built from the ground up based on you. 

  • Your height determines the cut.
  • Your movement shapes the fit.
  • Your adventures define the warmth.

The result is a system that traps heat more efficiently, eliminates dead space, and performs exactly how you need it to night after night.
