Review: Carries everything & more, high quality!!! - Excellent rucksack! This is a very high quality rucksack that has exceeded my expectations as the price was so good! I am using mine for a work rucksack to replace a trolley case as I am finding they do not last and hurt my arms so I thought I would go back to a rucksack. After looking at a few options I came across this one and I did read the reviews and thought it was worth a try! I am so happy I did! It does everything and more that I wanted it to do! There is so much space for my laptop & headset, my A4 chunky folder, a white board & pens, a waterproof coat, all of my e-cig, purse, phone etc There is also a fabulous clip that has a push button so you have quick access to keys/languard. There is also a handy zip pocket on the back which is an excellent security pocket as it is hidden against your back when wearing the rucksack so the items are not on show. The quality of the material is second to none, it’s very high quality and feels durable and waterproof! I love the colour, I went for the Blue and it’s beautiful and a nice change from what I normally choose which is black as I have a black Labrador and boy he can’t half shed his fur! But I found the grey been too light for me so when I saw blue I thought I would give it a try and it’s better than I expected! It also has space for my water bottle and umbrella. This rucksack has exceeded my expectations!! I would highly recommend and when I need to replace I will be getting another as I know this rucksack will last me a long time!
Review: Great Quality and amazing value for money - Ive had this bag for 2 years and done many trips, it has been excellent and is still standing the test of time, ive packed it full to the brim with duty free / jackets / clothing - no issue. The pockets are cleverly designed and the Laptop compartment is genius. I never expected it to last this long. and its still ging strong !!
