This n' That
Internal vs. External Frame Packs
- rigid frame upon which pockets, pack bag, and suspension are attached.
- typically has lots of pockets for easy gear distribution and organization.
- good for carrying heavy loads, on-trails only, and on relatively easy terrain.
- more open space between frame and person's back for better ventilation than Internal Frame.
- dimensions of fully loaded backpack has wider, taller, less-stable profile than Internal Frame backpacks--very high center of gravity--(don't even try to walk under tree limbs or you could end up flat on your back).
- framing is an integral component integrated with suspension and pack bag.
- pack designed to fit snugly and comfortably against a person's own profile.
- very stable and functional off-trail as well as on-trail.
- snug fit against the body allows for better balance and maneuverability on rough terrain.
- narrow profile allows flexibility to venture into tight places.
- tends to be warmer against the back--ventilation not as good as external frame.
- typically, lack of pockets for organizing gear.
