Internal Frame Backpack Pluses and Minuses:
Internal frame backpacks have a streamlined shape because the frame, a flexible one, is inside the backpack. Since the pack is flexible and carries close to the body, it offers comfortable fit, low center of gravity, flexibility, and a relative freedom of movement to the user. Those features make internal frame packs an ideal choice for rock scrambling, off trail, winter ski touring, mountaineering. The drawback with internal frames is that they do not carry unwieldy loads easily and can become quite unstable and uncomfortable if you end up lashing large amounts of gear to the outside of the pack.
External Frame Backpack Pluses and Minuses:
External frame backpacks feature rigid, rectangular frames, typically made of aluminum or a more flexible plastic/nylon. The weight carries higher than a pack with an internal frame, so correct loading is essential. The frame carries the pack away from your back, improving ventilation and making the pack a cooler choice. Since the pack frame is somewhat rigid, it does tend to restrict moment. External frame packs also typically have a higher center of gravity, making them feel a bit top-heavy unless loaded properly. However, unlike an internal frame pack, the rigid external frame can carry ridiculously awkward loads quite comfortably and offer numerous lash points for attaching items .This feature may be appealing to the parent carrying almost all the gear while the other carries the child. External frame backpacks are ideal for very large and bulky loads and for long backpacking trips. But they're not for mountaineering or skiing.

Variable loading/closure choices in packs
Top Loading: Features one top opening into which you load, cram and stuff your gear. Many top loaders have an extension collar or tube that will add additional volume should it be needed and a floating top pocket to fit over the main compartment. Top loading packs re the most water-resistant of all the pack designs simply because there are fewer openings and zippers. This design is deal for backpacking, mountaineering, winter camping.
Panel Loading: For those who want easy access to their gear. You can open a horseshoe-shaped zipper and see all that is inside the pack. Will not hold as much as other styles, and if a zipper fails -- Oy vey! Ideal for light weekend backpacking and adventure travel.
Hybrid or Combination Loading: Offers the best of both packs: top loading for stuffing to the gills, panel loading for seeing what is inside without rummaging. More openings mean less water-resistance. A raincover is a must. Ideal for adventure travel, backpacking, hut-to-hut skiing.
