hey guys I went to sport chalet and REI and saw alot of those backpacks with those aluminum frames. Whats the difference between the aluminum frames and a regular backpack? is the frames function to distribute the weight so there are no stress on specific parts?

oh I was referring to something like school backpacks and backpacks that have frame like this http://www.bagking.com/Merchant2/graphics/00000001/Youth_scout_lotus_SMALL.jpg see the small black frame on it? I am just wondering if its just necessary
well to make my question better. Why would it be more beneficial to carry a framed back pack than a school back pack? and there are actual no framed (like school backpacks) hiking backpacks?

My understanding has always been that external frame packs are / were better for tral work, that hey place the weight on your hips and not your back and shoulders.
Internal frame packs were supposed to be better for bush wacking and climbing because the wieght is held closer to the body and you have better balance. Also they don't stick out and catch on thing as much as the external framd packs.
Thats the way it was 15 years ago when I was shopping. However there have been many improvements in packs and some of the internal frames are very comfortable. I have found that the external frames are a little cooler to wear because the pack is not against your back, butpersonally I would go with the internal frame pack.

Read Colin Fletcher's The Complete Walker for a very good discussion of packs, frames, hip belts, etc. The technology has changed a lot since the old Trapper Nelson (read: pain) days.

Whether the packs are internal or external frame, the idea is to vector the weight to your hips rather than your shoulders. The shoulder straps become simple stabilizers rather than load carriers.
External frame packs are good for strapping odd stuff to. If you use heavy camera gear, scientific instruments or a dead deer , they work well. They are an older technology. They giver better air circulation, but are gnerally heavier and they ride high and wide, so they catch brush and such more than an internal frame pack. I've picked up a couple really nice ones at garage sales dirt cheap-- like $10.
Modern internal frame packs still have a frame, but use a plastic sheet or aluminum stays that transfer load from the shoulder strap mounts to the hip belt.
When you are hiking, packs are part of a system and sized and built for a particular size and load weight. Check out Backpackinglight.com to get the ultralight view on all this. Ultralight packs don't use (or need) a frame because the loads are so much lighter. I can go for three days with a 21 pound load. Much easier on my old bones than 40 pound loads.
