Nifty backpack that holds more than you might think
This is a lovely well made and truly water resistant backpack. The only minor downside was the fact that if you go for a run wearing this and you have a filled water bottle in one of the dedicated holders it tends to pull down on the weighted shoulder strap, which can cause discomfort. As there is no front fasting to stabilise the backpack whilst running, the only solution would be to put the water bottle in the main compartment. It's not a deal breaker. As for water resistance, well I was caught in an absolute deluge on my way back from work, and after a half hour trek I discovered that not one drop of rain had made it's way in. The capacity of the backpack can appear deceptive. It seems you can cram a lot in. Much more than you might think. Although I haven't tested this myself yet, I think you could easily fit a change of clothes, a pair of trainers and a various other bits and pieces and still have room to spare. All in all, in comparison to my last backpack this is lighter, holds even more despite being a smaller stated capacity by four litres and is will keep your belongings dry.

Great bag 💼
Purchased for my teenage son for going back to school in September (assuming they do go back). Excellent quality, main reason for buying is the separate shoe compartment. My son cycles to school and doesn’t have a locker at so the bag needs to comfortable to wear all day and big enough to fit all his books, his Chromebook and PE kit when needed.Large spacious rucksack with laptop 💻 and phone 📞 sections.

Amazing!
I have a few friends that have UA bags but had always been put off due to the price, I luckily bought this on offer but now seeing the quality first hand I would 100% buy full price.Lots of space and good depth.Multiple storage pockets so it's very easy to split up items i.e. shopping.Comfortable padded straps which is a massive bonus when the bag is heavy.I know I will easily get a few years out of this bag!

BUY IT! DOES EVERYTHING RIGHT
Amazing bag. Literally best bag I've ever brought. I often carry loads to study with and this bad can carry: 4 binder folders and a laptop,. 2 small note books and my pencil case all in the large compartment. The second biggest car carry my lunch, my large over ear headphones and lots of small stuff in the pockets. The other 2 outside pockets are very convenient. I use the bottom zip to carry my umbrella and a small bag with just in case stuff like a portable charger. It could do with a sternum strap on those days traveling etc but overall this bag is amazing

Fashionable and useful school bag.
Bought as a school bag. Rigid back to keep books straight/ laptop safe. Good size, separate storage pocket for trainers or shoes at bottom.Soft pickets suitable for glasses/ phones etc.Middle pocket has sections of pockets would fit I-pad, pens etc in.Back pocket big enough to store lunch box, thin coat and school books.Has 2 side pockets for drink/ water bottles.The only problem with it I have found is that although it says it is water repellant it still let water in when there was a bad down pour.

UA does it again!
This rucksack has exceeded my expectations for the price (£30 odd quid). I have seldom bought something from UA that isn’t greater quality than its close rivals (Nike/Adidas etc). This bag is no exception. Spacious yet compact, illuminates in the dark when walking on the road, water proof, and versatile (aesthetic).

Awesome backpack
A nice backpack with lots of room. Separate compartment for shoes at bottom. Used this in light showers few times and water resistance works well. All in all good purchase in this price range.Go for it.
