It’s rigid and flexible design facilitates heavy load carriage and provides an exceptional load transfer mechanism to the hip belt when properly fitted. Exterior frames also have multiple attachment points that readily support lashed bulky loads and gears like tents, sleeping bags, and bear canisters.
- They feature vertical bars slightly curved to assume S shape, and cross members holding both sides together. Some are design with a bottom shelf, providing an ample space to fit a sleeping bag.
- The frame disconnects the backpack from the back and hence providing sufficient room for air circulation between the backpack and the back. The separation distance makes an External Frame backpack cooler to transport in hot weather but very difficult to balance on the back.
- Some External Frame Backpacks are designed with a cross member extending beyond the backpack and body height top. This extension allows for lashing of extra loads on the upper side of the backpack and provides an additional grab point to easily remove it by lifting the backpack from the back.
- They also feature rigid Aluminum frame that fully controls the countering movements on the shoulders and hips and reduces the twisting force from the torso.
- They feature a frameless construction with all its structures such as the waist belt and shoulder harness sewn directly to the pack’s frame. The waist belt and load lifters are adjustable and removable to allow better carriage and movement with the pack.
- Strong and durable external body casing made up of all-weather synthetic fiber that can resist almost any severe condition and hence lasting longer.
- They are fairly heavy and hence allowing easier transportation of goods during hikes or expeditions.
- They allow for bigger load carriage and very effective for long expeditions where heavy loads of up to 120 pounds are conveyed.

- High durability since the backpack is made with strong fiber to endure extreme weather conditions.
- They have fully stable internal pack with the hip belt and the shoulder strap mounted on the frame itself.
- Since the pack is strongly attached to the frame, it provides a strong and rigid suspension system.
- It provides a bigger load carriage capacity and additional attachment points hence can be used for hikes and long expeditions.
- It has a separation space between the back and the backpack that allows for free air circulation and high cooling abilities in hot weather conditions.
- They are much lighter, stable and cooler than old-style framed packs. This is the case because of its aluminum frame and a separation space between the pack and the carriers’ back.
- Flexible and adjustable structures, most external frame backpacks have adjustable shoulder straps and attachment points that can be aligned to fit the carriers’ load and the carriers’ back positioning.
