NOTE: If you would like the Flight 40 Pack body, but say you would like to purchase it with separate components than the ones offered, you may add the pack body to your cart by selecting the color you prefer and choosing none for both the vest size as well as hip belt size. You will then need to add the components you would like as a separate item to your cart. All of our pack components can be found here

  • 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 Delrin 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.

    ❤❤❤ my new bag

    The flight 40 is probably the BEST bag I've ever used! Whether for a14er or just a good day trip, this is THE bag. I especially love the vest style, which makes getting to things incredibly easy. Fit is awesome Awesome product!!

    Flight 40

    Absolutely love this Pack! I have been backpacking for many years and have suffered from collar bone issues with other packs, I have tried many manufactures and nothing helped! The suspension on the flight 40 disperses the weight evenly through out your shoulders and chest. After hiking long distances you can take this backpack off and it feels like you haven't had anything on.
