I bought this bag to replace a stolen one. I liked this bag that much. First, this is a SC cotton bag, not a Sechunk bag as advertised. The rest of the description is correct. There is no zip pocket on the back, there is an internal one. It's small. I use it for small items that I don't want to lose at the bottom of my bag (like keys). It is approximately 5 x 7 inches and is lined only, not canvas. Good canvas, durable, you can take it with you. Good size front pockets. My wallet is in one and my cell phone (Galaxy S8+) in the other. Pockets 7 x 5.5 inches. Side pockets are 6" x 4" and feature a buckled leather flap. My phone fits in perfectly, but isn't as tangible with a clasp. Thick cloth lining, not canvas but thick. The strap is attached with metal rings and is adjustable at both ends with a metal ring. The bag itself zips closed and has a messenger valve attached with magnetic clasps. One feature I love is that the flap has adjustable straps so you can tighten it when your bag isn't full or loosen it when you're packed. I've attached a video to show all the features. Not a very good video but I hope it helps! 4 stars for the strap being adjustable on both sides, which annoys me because you have to adjust them the same way to keep the shoulder rest in the middle.
