This is truly an amazing and durable bag. Excellent for travel or hiking or any outdoor activity. The two side pockets are great to hold a water bottle. Each pocket has so many uses. In one of the pockets there is a clasp to attach spare keys or a small wallet with a key ring attached. Very durable canvas material. Easy to clean and washable. Adjustable strap for added comfort. Classic. Great quality too. No holes or stains. See photos for measurements. Thank you.
