Product Description
The most advanced design of a sleeping bag ever!
Like the name implies the foot end of the bag is shaped like the bow of a boat. The shape causes the Lamilite fiber to come together at the foot end of the bag increasing the insulation markedly and thereby increasing the Lamilite ability to insulate. Then there is the hood section of the bag. It is flat to begin with but when you start pulling the draw cord in tight the hood begins to form and a massive amount of insulation forms around your head.
The first bag that I am producing with these changes is the Ultima Thule which is a -20 degree bag, the next model will be the Antarctic bag.
The cost is no different than the standard model I have made for 26 years.
