## Description

Review: Nice, Big Backpack - Only had the bag a few days, but build quality doesn’t seem to be bad, to be honest. What has hit the mark, is definitely the size. There is literally bags of room in there, in all four compartments. The back compartment has plenty of room for laptop (slips easily into an internal pocket - like many bags - but there is plenty of room for other items to fit in the compartment, including in the second pocket). The next (main compartment) has bags of space. Could easily fit trainers and gym kit and your lunch. Big front compartment zips all the way down and has lots of pockets for cables, phone charger, pens, etc. and then there’s a smaller compartment at the front of the bag, great for you headphones etc. The shoulder straps have plenty of padding, so comfortable to wear, even if fully laden. The compression straps on side are a good idea, which hopefully take some pressure off the zips, if you load up your bag. The side bottle holders are still perfectly usable, with a 750ml bottle, even when the bag is full. There’s also a strap so you can slip the bag onto the pop up handle, of your travel luggage. Overall, smart looking bag that ticks most boxes.
Review: Amazing and well made - Well made, very spacious, loads of pockets, comfortable arm straps, waterproof (confirmed), laptop section. Used for college, really impressed, would buy again.

## Questions & Answers

**Q: When not full, is this bag soft enough to "squeeze/fold" into 20x30x40cm (to comply as under-seat on flights)?**
A: Positive. No problem to do that

**Q: What is the maximum voltage/amperage that the cable supports?**
A: The Voltage is 5 Volt, normal for charging with USB. It can run 2.1 Ampere (fast charging)

**Q: best back pack 60cm or 24ins**
A: Not clear what you're asking, if you say that the back pack is about 60cm height or if you can fit a 24ins laptop or screen? Well. You can just fit about 21 inches laptop, a gaming one comes perfectly inside

**Q: How suitable would this be for a supermarket shop? I.e. A supermarket hand basket piled up high with food?**
A: If your shopping didn't have too many bulky items in it, it should hold a baskets' worth. Never tried it though. My son uses it as a school bag, holds a chrome book, alot of heavy books and folders and a packed lunch with water bottle!

### ⭐⭐⭐⭐⭐ Great bag for travelling - so many pockets!
*by K***I on 3 February 2021*

I'm impressed with the quality of this bag. I have bought others previously which were intended for laptops and they don't last 5 minutes and didn't have this many pockets for everything! This one already looks far better quality. PROS: • Padded straps will help prevent cutting in when carrying a heavy bag • Large capacity for food, clothing, electrical equipment etc • Reflective strips to make you more visible at night • Water-resistant • Anti-theft hidden pocket for valuables • Able to charge phones etc on the go whilst in use • Lots of inner pockets to sorting items • Lots of clips & lanyard hangers for sunglasses, card passes etc • Big enough to carry my large 17" Macbook • Can be opened 180 degrees to pass through airport security without needing to empty the entire bag into a separate tray • Has a strap on the back to put over suitcase handles CONS: • Haven't found one as yet I am therefore giving this item 5 stars as it looks very good for the price. I spent far more on my previous bags & luggage for when I'm travelling. My other half has already got his eye on it for work, so I may end up losing it to him! I can pack this as either hand luggage or an overnight bag. It's big enough for a change of clothes, my makeup bag as well as my work laptops & other stuff. Will make travelling for overnight stays with work far easier, especially on trains etc where it's hard to have a wheeled suitcase due to space - this will easily fit on the luggage rack above me or under my seat. I like the idea of being able to plug my portable charger in & drop into an interior bag pocket (instead of me having to carry it in my hand or pocket) and then I can plug my phone into the USB port on the side of the bag & use it whilst on the move. Makes following maps & things so much easier & no fear of running out of charge whilst I'm using it. See my attached video for a full tour of the bag & all the pockets & accessories. As with all my reviews, if anything changes I will update my review accordingly.
