The Six Moon Designs Flight 40 FKT Rucksack is designed for Adventure Racers who require a smaller pack but with improved stability over standard offerings.  

Six Moon Designs says:

At 44 Liters (2700 ci.) and 39 ounces for the Flight 40 Fastest Known Time (FKT) is designed to function as an ultralight backpack with the use of our vest system and our supportive and flexible hip belt. All together you've got a light weight pack that's comfortable up to 30 pounds. It has been tested with loads in access of 40 pounds with zero sag in either the pack or hip belt.

Flight 40 FKT Support Structure

Starting with a Vest Harness that offers excellent load carrying capacity on its own. The vest is attached to the pack in two places and, when tightened, is designed to pull the pack body up and into your back putting the load onto the vest system. When combined with the Hip Belt the pack will hold firmly to your body and keep the pack from moving around while hiking. The Hip belt articulation is accentuated by our unique closure. Each of our straps are independent and terminate at the buckle. This allows you to set different levels of tension between the top and bottom of the hip belt. Straps that don't have two adjustment points on each side and simply loop between the top and bottom of the belt will reset to a central position as you walk.

A Delron hoop stay inside the pack bag, provides enough support to enable load transfer with minimum weight. The bottom of the stay is directed back to a junction to the center of the pack. This junction provides a direct connection between the stay and the hip belt. Typically with ultralight packs, the stays and hip belt are separated by several inches of fabric. The result is that when weight is applied to the stay, the pack sags.

With the Flight 40, all of the downward force from the stay is transferred directly to the hip belt. With the hip belt and stay, the load radiates out over a large surface area eliminating pressure points.

Six Moon Designs' Flight backpacks are designed with jerkin type shoulder straps and comprehensive hipbelts that provide the user with much improved stability compared with standard packs. This will be especially important for Adventure Racers who will be running for much of the time. The hipbelt can be removed and a stable carry can even be achieved using the shoulder straps only, because of the tensioning system employed.

The basic distinction between the two setups of the Flight 40 and the Flight 40 FKT is that the Flight 40 FKT utilizes the Vest Yoke. While the Flight 40 Backpacker uses a more traditional standard Shoulder Yoke. The Flight 40 FKT pack is pretty simple, a shaped bag with a drybag style roll top closure, but the hipbelt and shoulder straps offer eight small pouches between them in addition to the two larger side pockets on either side of the main bag. So, keeping gear and food to hand is easily achieved, a critical requirement under race conditions. The pack is well constructed with durable materials, so despite its weight its quite a tough pack
