Can air be warm? 
Makers of down jackets, vests and sleeping bags have used air as a medium of warmth for decades. Using space between down traps air, keeping it from altering temperature, and allowing you to stay warm. 

We discovered a way to use a synthetic material, called aerogel, to do something similar, but in a much thinner, more attractive way. 

Warm, but thin
Composed of over 90% air, our proprietary SolarCore aerogel has the lowest thermal conductivity of any solid. What does that mean? That it's not only extremely strong, durable, and flexible; but it's 2- to 8-times more effective than traditional insulation. Plus, SolarCore is compression-resistant and waterproof —something your old goose down jacket certainly isn't. Air, it seems, is truly the best material for outdoor activity. 

This translates into a high-comfort, low-profile jacket, reducing the relative weight and bulk of the garment to allow you to perform outdoors under any conditions, without restricting your movement.

Our Oros Jackets don't compress or lose performance, they're waterproof and hold up to a normal wash/dry cycle, ensuring you can thrash the mountain without trashing your jacket in the laundry.
