This is a very good quality piece and it’s designed to meet comfort and aesthetic. It is a spacious bag. I love that I can have separated work items like laptop etc from a gym kit or anything else, even a grocery. Easy accessible compartments and solid waterproof material. Definitely highly recommended for an active person. This is not going to be my last purchase from the brand.

Lovely design with some great practical additions like the side access zip for reaching into the bag without having to unroll it.

Great backpack with good compartments for small ins and outs. Would benefit to have the passport pocket as n other backpacks for easy access to passport. Don’t quite fully understand the inside water bottle compartment as it bumps into the exterior water bottle pocket. Maybe I am using it incorrectly? Otherwise a great bag that protects electronics and provides space . Great for travel

4 stars instead of 5 after six months of traveling. Why? Well, on the positive side it's built like a tank. This should last several years. On the con side, it's built like a tank; it's very stiff, on the heavy side in my opinion (when you load it with typical things you need to get to it gets weighty fast) and not very flexible. I love the roll top and especially love the shoe compartment (which I use for my noise canceling headphones because my size 14 shoes are not getting in there). It's not exceptionally stylish IMO, but I suppose stylish enough (there are other practical bags that are better looking). The HUGE disappointment for me if the narrow, single strap to hook on your wheelie handle. This is just dumb and seems like an afterthought when to most of us who travel a lot it's essential. On a number scale I'd give this 6.5 out of 10. Solid, close, but no cigar. I probably won't be using this much in the future frankly. Too much marketing behind it maybe? A lot of potential though on the plus side.

Excellent bag with serous enclosed protection, just the right amount of access points and carries very well. I brought this after I received excellent and exceptional customer service with a replacement iPhone case. I’m sure is any issues arrive with this backpack they will be just as attentive. 5*****

Solid backpack - I’ve only just used it since purchase. If u are looking for an all round heavy duty pack, then this is the one. Holds plenty, safely. Easy to access without opening up the whole thing. Slick storage all gear protected.

After a lot of research I decided on this backpack because of its versatility and aesthetic. I am super happy with my choice. The wet compartment is bigger than expected and fits my whole gym bag. The tech compartment ist very generous. Overall the perfect allrounder and worth the extra weight.

Finding the back excellent.
While it’s a bit heavier than some other options the broad straps are really comfy. This compensates for the weight. I love the way the compartments work especially the side zip to the main section. Inspired. It just works.

Solid constructions be build and can confirm that in wet weather, the backpack performed. The front zip to access the inside is great. The only quibble I have is that whilst the aerofoam laptop/ipad compartment is great, it is quite tight to the point I doubt I could put both a laptop and iPad in (I don’t). That leads me to my next (negative) point - there doesn’t appear to be a natural pocket to put my phone in. Again, when I put my laptop in, it’s so tight that I am concerned my phone screen may get damaged. This has resulted me in putting my phone in the side pockets (more designed for flasks and water bottles). Concern here is that those pockets are fairly loose so phone could pop out (it shouldn’t) but risk is there. You could of course stick phone into the main body of the bag but then quick access would be tricky.

All in all - solid 4* but I have a £40 waterproof roll top I bought in 2020 which is still going strong and has multiple front access pockets. Hope the next iteration of the bag solves this issue

This backpack is awesome!! It’s so well made, it’s practically, executive and multifunctional - don’t procrastinate in purchasing this. It’s not just a bag, it’s an investment for life!!

Handy size with useful expansion, usual same great material quality of the laptop cases, (of which I have two sizes). Wearher & impact protection without excessive over all bulk seems to be what appeals the most.

Very good. The shoe compartment is a game changer. However, the backpack is very heavy.

backpack is amazing. the side pocket to enter the rolltop is extremely useful and I use it as the main way to access things. if I would change anything, I'd add an inner pocket to the rolltop, as organisation can be quite poor there and the number of places where you can put small valuables is limited (keys, passports, etc). the strap used to place the backpack on luggage should also be horizontal rather than vertical.
