## Description

Durable 50L backpack with insulated cooler, multiple pockets, padded laptop sleeve, and water-resistant design for versatile storage and organization on-the-go.

Review: Brilliant. - A laptop rucksack that is large yet can also fit in a lot of other things...and I do mean a lot. The insulated pouch on the front is surprisingly handy, I actually use it a lot more than I expected (usually for keeping bottles of water cold), it keeps cold things cold without using a freezer pack for at least two hours. I don't know if frozen things would stay frozen that long but cool things seem just as cool as when they were put in after a few hours. Aside from having plenty of room and lots of pockets to put things in, the overall quality seems to be very good with no noticeable defects or issues and while the part at the back where a laptop goes is not very padded or protected as such it does fit in a laptop which is already in a case or sleeve and mine is in a waterproof padded cover so for me it isn't an issue although I did also use it to take a big heavy older laptop to a friend's and it didn't have any issues with that either. I can't attest as to just how effective the waterproofing is as I sprayed mine with some grangers repel spray I bought on desertcart at the same time and it made it able to stay dry inside even in heavy rain, I believe without such waterproof spray it would be fine in a light shower but in a long heavy shower of rain it may get a little damp inside otherwise. Its a very good rucksack in its own right but the added separate part for a laptop makes this even better and the price is very good, well worth the money spent on it. The back part would probably fit in two wide laptops, it certainly fits on in a protective case, and the upper front pouch above the insulated section fits a kindle paperwhite in easily so you could use this to carry a kindle a laptop a tablet and even shopping all at the same time. Yes it is actually that good.
Review: Super bag - I can’t rave about this enough! It’s fantastic, great to have a space for lunch, good size, strong materials. Perfect for work!

*by A***H on 5 February 2026*

Love this backpack, can fit so much things in there as well as it having a convenient spot for my power bank and keeping food insulated. The secure pocket at the back and dual zip design are must haves on a backpack of this size. Can't recommend enough
