The Ultra Light is a +20° F (approximately 0° C) rated mummy style bag. It is available in our standard three boat foot sizes.

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's 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 cost is no different than the standard model.


When the Overbag is added to the Ultra Light the temperature rating becomes -20° F (approximately -30° C). When both bags are combined you have the Ultra Light FRTSS.
