Overbag for all FTRSS's in the Boat Foot Mummy Style

The most advanced sleeping bag design ever is now available in an overbag!

The Overbag is a +35° F (approximately +5° C) rated mummy style bag. It is available in our three standard boat foot sizes.


Please note the slightly larger size for the over bag. This is so it will fit comfortably over any of the other bags when the FTRSS is created. Also note that a larger roomier bag is necessary for warm weather use.


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 I have made for 26 years.
