I found the Seventeen bag through searching for a burgundy bag and purchased if for what it promised. Glad to say it delivers and looks amazing while doing so. Additionally it can be used for most of varying reasons we buy a backpack. It is also completely Vegan.
I don’t need to carry folders and files so can’t comment but my 13in laptop does fit easily.
I haven’t tested the water resistant part so didn’t rate for that but it certainly feels water resistant.
Currently I was carrying all the things shown in the photos and they all had their own compartment and pockets to keep it organised. A very smart bag in design and looks. In the video you don’t see the hat and waterproof jacket in the bag but they easily sit on top in the big pocket.
The bag fit in an iPad with case (11.5x9in) water bottle, cutlery in own bag, 2-3x zip bags with accessories and cables, glasses case, numerous multi tools and stationary, a hat and waterproof jacket. Without the hat and jacket the bag would easily fit in a lunch box too.
The only addition or change I would make is having chest strap buckles, simply because I like having them. If a new version with these was introduced then I would definitely buy it, alternatively matching straps sold separately as an extra for now I guess.
