Backpack is very high quality. Accessories though plastic, but very strong. For everyday wear or cycling the most it. Sizes allow you to put all sorts of trifles, which I usually shove on my pockets. Ordered 19 inches, the largest compartment will fit 2 bottles of one and a half liters. For documents in the folder is not suitable. The seller is super, sociable, at my request sent the next day after payment. Moscow reached 21 days, 8 days of which traveled across Russia, from Yekaterinburg to Moscow. I recommend to buy from this seller.
Item received in less than 3 weeks. Bag looks great! Packaged well. Would recommend and would buy again.
It's not an unpleasant experience...just the bag is smaller than what it looks like in the picture..but will work with it..
