Clearly designed by someone using a backpack. It has the features you need it to have, and helps you keep things organized and IN PLACE. It’s very compact, but the design and layout of pockets give you effective use of the whole volume available.
Laptop pocket is spot on, tested with a 14” and 15” laptop (Lenovo T-series). Good protection.
Seen reviews stating that drinking flask pocket is too small - fits perfectly for my Camelbak EDDY+ vacuum flask, so there you have the dimensions I suppose.
The quality of the nylon is also worth mentioning. If get it dirty you just rinse/wipe it off. Tested in Nordic/sub arctic climate during summer months, so yeah – waterproof.
