The Klymit Ulaar jacket provides cold weather protection while without bulking you up like other winter jackets do.
Inside the coat is a thermal heating system powered by argon gas that can be enacted when its chilly and then released when it gets warm. The use of this gas is being referred to by the company as NobleTek technology and they have been using this type of insulating system in their vests since 2009.
The Ulaar coat is the first jacket to use the insulation system and is ideal for those times when the weather fluctuates and you would be left either sweltering or freezing if you didn't bring extra clothing along with you.
Lining the jacket is a carbon bamboo fabric that is antimicrobial and fast drying which ensures comfort and dryness.
