Review: Tested for 3 years, perfect for what I need from a backpack - This is a review based on almost three years of experience by a user (me) who's probably the kind of person that subjects their backpacks to the most extreme stress due to my habits. I cycle to work every day and on a normal day carry around 4 kgs of lock, replacement clothes, laptop, spare battery, cycle repair tools, and so on. On Tuesday I add to that a full martial arts kit with shin pads, two types of boxing gloves, mouth and arm guards, etc. On weekends I buy 2 weeks of groceries that I need to bring back on my bike and typically I load the backpack with maybe 5-6 bottles of wine, juice, spirits, etc. as a minimum (but I tend to cram it until there's no space left). I've tried many backpacks in the past and they all have some substantial defects, have straps that break down or get stripped off the body easily, are not big enough, etc. I got my first version of this backpack 2.5 years ago, and I was surprised by how capacious it was, and how the straps felt sturdy and solidly attached to the body. It lasted a year (which, given the demands I place on the thing is not a bad performance), then the plastic clips on the straps broke down so I decided to replace it with the same model as it was cheap and I didn't want to go through the uncertainty of finding a different model that would inevitably reveal different defects. On this model, I had the pull tab on the main zip suddenly come off after 16/17 months, while all the rest was still standing. I might have tried to get that replaced, but honestly it's likely to cost more than the 24£ that I'm paying for my third model. Overall, this is big, has enough pockets for various types of needs, is surprisingly cheap given its quality and absolutely great for my needs. Definitely recommended.
Review: Does what it says on the tin - Ideal replacement for my sons college bag. Fits everything he needs plus room for more. Good price, good quality, one happy customer.

## Questions & Answers

**Q: What are the dimensions of the large second compartment? I need to carry a 17x17cm lunchbox which laptop in othe compartment plus files etc.**
A: Yes you will have plenty of room. A great bag.

**Q: I just bought this bag & tried the charging port, but does not work. Has anyone else had this problem?**
A: Yes I had the same problem I think the cable fitted is too heavy for transportation of charge. I just don't use it.

**Q: Hi i am going on a trip soon, just wondering this bag apparently is 41x27x54cm but airlingus underseat dimensions are 25x33x20cm. should i chance this**
A: Hi I’ve taken it on a plane and it fitted under the seat. But I think it depends on how much you put in it.

**Q: would this accept velcro camera dividers so i could use as a camera bag as well**
A: The size should be fine for a lot of camera equipment but it's not rigid like a traditional camera bag and there's not velcro straps in place to attach other velcro straps and so I'm not sure it would be suitable to properly protect your equipment or keep your velcro padding in place. That said, if you have fabric adhesives you could probably create attachment points. There's so many potential variables involved there can't be certainty. Perhaps just put a small camera bag inside this one. Perhaps someone else will have better advice.

### ⭐⭐⭐⭐⭐ Huge and practical
*by A***! on 8 October 2025*

I have purchased this for my kid who goes to secondary school and has to carry loads of books and his PE kit. This backpack is genuinely huge! Everything fits in and it has more than enough compartments. Additionally it is very comfy to wear and my kid loves it. He has only had it for a few weeks however there are no signs of wear and tear and so far there have been no faults/ any issues.
