Ravnø Exoskeletal CF | Jötunn Load System

The backpack is designed for those embarking on a 3-14 day hunt and need to carry long distances or heavy loads, both into and out of the terrain. The load-bearing construction features an anatomically “X-woven” carbon fiber plate with vertically embedded Kevlar reinforcement rods.

As a user, you have the ability to customize the backpack and harness according to the length and width of your back by adjusting the harness attachment point and the angle of the CF plate. The width of the carbon fiber plate provides excellent lateral stability and sturdy load capacity. The backpack has 3 internal and 7 external pockets, including external pockets suitable for a spotting scope/binoculars, an internal hydration bladder or hunting radio with cable/pipe holes. The backpack features SpeedMount™ quick-release mechanism for weapons, which can be mounted on the right or left side as needed. The backpack’s freight shelf can hold approximately 45L, enough to accommodate game meat. It has webbing and ice axe attachment points. Mil-Spec. It includes an internal Hydropack bag with a front passage. There is also a passage for a radio/communication device/hydration pack.

The Jötunn backpack is designed as a platform for our bags. After years of product development and numerous prototypes, we have managed to create a load-bearing construction that prioritizes low weight and excellent load capacity relative to its dimensions.

Unlike carbon fiber rods or aluminum as the load-bearing structure, our design can withstand much greater loads in terms of tensile strength, compressive strength, and flexural strength. The weight increase from using a plate instead of rods is negligible, while the difference in the load-bearing system’s ability to handle heavy loads is significant.

We have chosen Cordura™ 1000D Ripstop as the main fabric for the backpack and harness construction. The fabric is DWR treated, and a signal-colored rain cover is included. The total weight of the 85L backpack is 2686g. The maximum recommended load is 75kg, with a maximum load capacity of 150kg. The freight shelf (meat/cargo shelf) has a capacity of approximately 45L if not built too high.

We aimed to create a backpack in the “intermediate class,” suitable for long weekends or week-long hunts without the need for extensive expeditions. The backpack should also function as a platform for transporting game meat from the mountains or out of the forest when necessary. We settled on an 85L capacity as the optimal intermediate-class capacity. The size of the backpack can be reduced to approximately 60L by removing the top lid and using the intermediate lid. Additionally, the backpack features a meat-carrying platform between the frame and the backpack, with a capacity of approximately 45L. The SpeedMount™ quick-release mechanism for weapons can be mounted on either the right or left side, allowing both left- and right-handed shooters to utilize the system. Place the rifle stock in the “carry bag” and lock it against the backpack. When you need to retrieve the rifle, hold the barrel with one hand behind and above the shoulder while pulling the quick-release cord. The locking buckle will open, allowing the rifle to swing forward into the shooting position.

The recommended maximum load is 75kg, with a comfortable load for a 3-day trip ranging between 16kg and 30kg, depending on physical condition. Under normal circumstances where you need to move, hunt, carry 3-day rations, a one-person tent/sleeping bag, and lighter equipment, our experience shows that around 20-25kg works best for most people. Some Ravnø guys are in much better shape and can comfortably handle 30-35kg, except for August, who can handle 60kg without breaking a sweat.

Carbon fiber components are used in rockets and satellites precisely because of the carbon fiber’s Coefficient of Thermal Expansion (CTE) properties. From superheated extreme temperatures to nearly absolute zero, the CTE of carbon fiber allows it to withstand such extreme temperature fluctuations.

Hydration bladder is not included with the product.

Tech:

Frame with meat shelf – 45L. 80L main compartment. 2×2.5L front pockets. Double lid system, the top lid can be detached and used as a separate daypack mounted on the carbon frame. In other words, you can leave the large backpack at the tent, attach the lid to the frame, and use it as a daypack.
