ArcEnCielWomen Sling Chest Bag Canvas Backpack

Q: is backpack bag carrying lower your back or up in middle of your back that depends on adjustable shoulder straps can make shorter?

Yes, the straps adjust to make them shorter or longer. Please note this bag is much smaller in person than it looks in the pictures.

Q: Is this 100% cotton canvas? And the interior cotton also?

I have the grey color. I don't see any tags in the interior stating what the fabric is made of. The canvas does feel like cotton. I saw an answer to by the seller to a similar question stating the interior is polyester. In the one I received it's more like a lightly brushed polyester not the slippery type. Hope that helps.

Q: What size is the hidden pocket on the back?

Thanks for your question. The size of this hidden pocket is 14cm(Width) * 15cm(Deep). Thanks.

Q: How big are the pockets? Can somebody post more pictures of the inside and outside? Whats the durability of this?

Very durable. Many pockets and most on the front and back are zippered. This bag has a very nice compartment that faces your back when wearing as a backpack. I actually use it as my main "purse". I absolutely love it!
