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.

How cold is warm?
With a rating of -50°C (-58°F), the Oros Lukla Jacket will keep you toasty down to ungodly temperature. From climbing Everest to skiing Vail, there's not another jacket you'll need. But, because of our SolarCore aerogel's unique properties, the Lukla will keep your core temperature down even under hot conditions, should the sun pop out and heat the landscape (even up to 148°C [298°F]). No matter the conditions, the breathability combined with this low-profile insulation keeps your body temperature regulated.

We put Michael in our first prototype jacket and blasted him with liquid nitrogen. How'd the jacket hold up? See for yourself in the video above.
