What is this Back Pack made of, The Exterior surface?

I would call it a heavy-weight canvas which is typical of this type of equipment. It is well made.

It is the same material as the rest of the surface you see in the photos. The black neoprene type of material. It is not a hard rubber or anything special. I think it would last a while, but I would not take it on many hikes, and toss it on rocks without expecting it to start take damage points over time.

It's made of good quality material and the padded computer space is up against your back underneath the zipper. I used mine in moderate rain without an umbrella with no leakage. Can't say what would happen in a downpour. In the past with other backpacks, I've used a plastic shopping bag and tied the handles underneath the straps and just let it lay over the top of the pack for added protection in heavy rain. Haven't done that with this one yet. I think it's a great pack

The backpack is a high quality product with reinforced seams on the top handle, even a metal cable inside to strengthen the handle. The backstraps are well padded for comfort and are well sewn on with reinforced seams. The zippers worked very well and the thickness of the backpack material demonstrates that this will be a long lasting product. The person I bought it for is very pleased with the product and uses it every day to carry various electronic products and quite a bit of weight. I hope this helps.

The back portion of the case is lined on the inside with hard plastic, but the front is just the material alone. Which is the typical backpack material. It may resist some light rain for a short time, but I wouldn't count on it withstanding some hard rain. I know my son has walked home in some light drizzle with it and it didn't hurt it.

Its rubber on the outside, but does have a thin nylon liner inside. Mine is tearing a little around the handles and zipper, but I have used it everyday now for almost 2 years... a friend patched it up for me (as I have no sewing skills) so its good as new again!

I do not know what material it is made of, but it is well sealed and I think it would be fine outdoors.

the bag itself is a backpack with back padding, shoulder straps and a belt.

It is metal with a white rubberized coating. I love it because it fits a lot of items.

Nothing. It's the same back pack. It's rugged and built withstand a full days beating.

The back and bottom are fabric. The back plane of the backpack has a semi-rigid piece inside surrounded by soft padding and a soft breathable nylon fabric exterior along its entire length. The bottom piece is a heavy nylon fabric with some padding. There is nothing like rubber feet or plastic runners to keep ground contact to a minimum. If the bag is dragged or slid across a rough surface it will begin to show. I found this bag to be better quality than most of the bags in the school supply isle at my local department store and as good or better quality than many at the local sporting goods/ camping supply store. The quality far exceeds the price.

The exterior is some sort of waterproof synthetic fabric. Soft and breathable. No issues with skin irritation. The prefold insert I think is cotton. Hope that helps.

This is a textile jacket. It has armor in the shoulders and elbows. The back protector is a stiff foam pad.

The top material is a crinkly material like some chip bags. The back is a lightweight polyester that is similar to bags sold for groceries.

The back of the pad is a vynal-like material and the pad is quilted fabric. The back is very pliable and holds up well to washing.

It is soft, sort of rubbery texture on the outside, Im not sure if it's leather or not, but a velcro strap and soft on the inside to protect it from any damages while you're traveling.
