Great bag for going from office to gym. Very durable, size is just right and a bunch of useful features.
Very happy with this bag. Looks good. Lots of space. Lightweight. Can be used both as messenger and bag pack. A few things could be improved though:- zippers feels a bit too thin in quality. Wonder how long they'll last.- Ergonomics of the bag pack straps could be improved. They have a tendency to slide of the shoulder with the least weigh on.- I would have preferred if all zippers were waterproof.
This is my favorite backpack. Size and functionality exactly what I wanted. I recommend
I’ I’m really happy with the quality! I could have had a lekker bigger front area- this is just the good size for business!
Very nice bag for traveling and attending to conferences. Just what I needed. I'm very satisfied!
Nice look, a bit small for the "climb" pocket size.
I purchased the bag due to its business like appearance and overall sleek looks to replace my much larger Wenger rucksack.The design is great with many multifunctional pockets. It has a protective pocket for my laptop and a second for my iPad tablet. There is enough room for the power supplies also.Overall a fantastic purchase. Now to the negative points which need to be seriously looked at. When carrying as a genuine rucksack the shoulder straps are the most uncomfortable I have ever experienced. They are sharp firm and dig into your shoulders nothing like the comfort of the Wenger. You cannot carry any weight for a period of time on your shoulders. They are also very difficult to adjust you can’t make small adjustments when on you have to take the bag off and ... MoreI purchased the bag due to its business like appearance and overall sleek looks to replace my much larger Wenger rucksack.The design is great with many multifunctional pockets.

They are sharp firm and dig into your shoulders nothing like the comfort of the Wenger. You cannot carry any weight for a period of time on your shoulders. They are also very difficult to adjust you can’t make small adjustments when on you have to take the bag off and change each strap and if not accurate you have a lopsided bag. A bit of a pain to be honest when this is supposed to be an all round rucksack. Probably wouldn’t purchase again unless the shoulder strap design is significantly changed.Looks 10/10Style 10/10Functionality 10/10Design 8/10 (sort the shoulder straps)
