The Only Jacket You'll Ever Need

Klymit 2

Two years ago Klymit launched its Variable Warmth Technology in a vest with sealed air/gas chambers that the wearer could inflate with his own breath, or Argon (the gas used to insulate between glass layers in your home's windows). Its premise: bodies change temperature drastically based on activity level, and the weather changes all the time. Carry less stuff and tweak your temp on the fly, whether you’re camping, at a game, on an expedition, or out for a walk, and you’ll be more comfortable.

Klymit is the first company to use Argon, a great insulator because of its low thermal conductivity, in apparel. The gas has allowed Klymit to create a 25mm insulation layer that is warm enough to be everything you need even for a South Pole, Denali, Aconcagua, or Cerro Torre trip ... in case you’re headed that way (in which case, take us with).

To date, Klymit has made a vest and a couple of sleeping pads, both of which use air chambers that, once inflated, conform to your body, capture its heat, and recirculate it. Now, through Kickstarter, they’re working on the Ulaar jacket.
