Very sturdy and lots of pockets for organising. The water bladder is a nice touch for those long days and when not in use, the internal pocket is a bit of extra storage. The tool pouch is brilliant and can take the basics for when you’re in a pinch, the fact that it’s removable is a nice touch so you can swap and change if taking a smaller pack for the day. The hard goggle case is the perfect size for your goggles and also a pair of sunnies for when you get off the bike. I use this as a commuter pack as well as for off-roading days, as it can take my work laptop (15 inch), but a bigger screen than that and you would struggle to fit it I think. Very comfortable and adjustable even for a woman’s anatomy and the chest strap pockets are great for quick access to your cards at fuel stations etc. Would highly recommend this backpack!
