Inflatable jacket warms up with puffs of air or argon

Choose between regular air or argon gas to inflate the Klymit Ulaar winter jacket to your desired degree of insulation.

Air up your jacket like a pair of Reebok Pumps.

As they say in "Game of Thrones," winter is coming. You could settle for a regular jacket, or you could get a jacket with adjustable insulation that can adapt to the weather on the fly.

Air chambers on the Klymit Ulaar Jacket can be inflated or deflated to change the amount of insulation. If it's colder, pump it up. If you're out hiking and working up a sweat, let some air out. An air pump tucks away into the left pocket, and you can control both the deflation and inflation from there.

The idea is that the air chambers capture your body heat and keep it in circulation around you. The jacket's also windproof and maintains its thermal abilities when wet.

There is an optional upgrade to an insulation called NobleTek. This uses argon gas for inflation rather than regular air. The company claims argon insulates three times better than the dead air trapped by other insulations. The argon itself weighs almost nothing.

A $165 Kickstarter pledge will get you a Klymit vest. It costs $250 to get the full jacket and $500 to move up the argon gas starter system with three gas canisters, an inflator, and a patch kit in case you blow a hole.

In the pantheon of weird jackets we've seen around here, the Ulaar actually sounds pretty useful. It's pricey, but so is a lot of other technical clothing. At least with this item, you get to harness the awesome power of argon.
