A high altitude speed climbing, Himalayan big wall, alpine climbing sleeping bag. The "La Fayette", introduced into the Valandre sleeping bag line in 2000 sleeps down to 5° F. This sleeping bag was the pioneer in the second generation of our Tubular bell construction. The design concept was very simple: to conceive the ultimate superlight high altitude expedition bag, to be used together with the Combi suit.
Speed is the key safety factor in low oxygen high altitude assaults as you enter what's known as the death zone. Once over 8000 meters, you can start to count down the time left before you have to be back below 8000 meters. Either you continue to head for the summit, or you hurry down.....If you stay, you are out on your own! The ultimate assaults are speed assaults in alpine style, meaning climbers with no support from sherpas, no fixed ropes, and carrying all their gear. This is where the La Fayette comes fully into the picture.
The La Fayette is a tubular bell construction, using pre-cut circular baffles (not anatomical). All stitches are tuck-stitched from the inside. The tuck-stitch technique has the advantage of being stitched though a double layer of fabric, producing a very strong and solid seam. The bag, being more of a climbing tool than a "normal" sleeping bag with a side zipper, has a "center half size zip system". The length of the zipper is calculated to be the minimum necessary to enter the bag, wearing a combi suit. The advantage of a center zip is, that whether you are laying on the right side or on the left side, you are not disturbed by the contact of a hard zipper. And you need to face the basic fact: once it's freaking cold, you need to get the heart and lungs off the cold ground, so you are "rolling over" on your side, in the fetal position, during the night. When you are on your side, your knees press on the front of the bag, possibly shifting the down from the front to the back. So, the La Fayette has a knee protection system, made out of three smaller and laterally closed compartments with a higher down density, than the two bigger ones on the back.
The draft collar is built into the inside cylinder, with a cylindrical hole just big enough for your neck. To avoid the possibility of any heat leakage, a semi-elastic adjustment system is placed on the inside. So from the inside, your hands can close the smallest little gap in the collar, all this without any deformation of the sleeping bag! As you roll over from your left to your right side during the night, you induce air circulation. To keep this circulation to a minimum, we added a semi-elastic adjustment system at the waist.
The La Fayette is more than a technical mountaineering bag, it's simply beyond any comparison worldwide. No other company has the technical expertise and the willingness to push technical limits to this level of ultimate perfection without any compromise.
