The ILBE Pack is designed to carry a load of up to 120 lbs but at the same time, it distributes the weight so it is comfortable to wear. The key features to the pack's comfort are in its internal frame with 2 metal ribs on the outer sides and 2 larger spars in the middle. These spars are already shaped to fit most people's backs but can be custom-bent if need be.

Next, the pack includes soft padding on both the hip bet and shoulder straps. The wide hip belt displaces the weight around your body with fewer pressure points. Both straps can be adjusted to custom fit your body and have a breast strap that can be raised or lowered to fit both men and women.

To keep the pack snug to your body you will find several compression straps along each side. These can be adjusted for different size loads and keep your gear in place throughout your hike. Both sides of the pack also include pockets which make a nice rest when carrying longer items such as trek poles or holds extra water bottles. You will also find heavy-duty zippers on both sides for access to your gear in the main compartment.

The back of the pack offers the ability to customize your pack with MOLLE accessories by using the MOLLE webbing and includes a compartment to help hold a hydration system or the ILBE Assault Pack which can be buckled down and tightened to keep in place. If you choose not to use the Hydration compartment or are strapping a larger MOLLE accessory to the back you can roll down this flap and snap it in place.
