Gr at backpack for work. My husband uses it daily and takes transit. Great safety features of reflectors on the straps and front of bag. Lots of space with laptop for his bag with h notes books, stationary, headset and chargers. Also other compartment has space for his 30 oz water bottle extra water bottles and lunch bag. Side pockets are mesh but elastic is solid to keep his extra hot water thermos and travel mug. He said with everything in it, feels heavy but when he puts it on its light and easy to walk with. Still a lot of room to use with all the items. Going to get another to keep on storage just in case.
