The Klymit Ulaar Jacket is perfect for the winter months as the wearer can adjust it to a desired degree of warmth using an air pump in the left pocket.
The Klymit Ulaar Jacket aims to take warmth and comfort to the next level. It features adjustable insulation that saves you from purchasing additional layers and also reduces the weight you have to carry. Using NobleTek technology, which insulates using noble gas, chambers in the jacket can be inflated via an air pump in the left pocket.
The Ulaar conforms to your body snugly, capturing your body heat and recirculating it throughout your core. It is also windproof and will keep you warm even when wet. Klymit is currently seeking funding for the jacket on Kickstarter, where you can get hold of the Ulaar for $250. You can check out their campaign video below:
