Bought this for my boyfriend. He's had it for 2 years now. It's holding on pretty well. No sign of tear yet and he uses it everyday. There are so many pockets in this bag, it's very useful. He was very impressed that it was made out of recycled bottles. It has been washed several times in the washing machine and still looks as new. Great design, I would definitely recommend it.
Dakine are most definitely a very reliable brand and I have been using their backpacks for many years now. I still have a Dakine backpack that I used for my school books many, many years ago! Other backpacks I have had in the past lost strength or the straps began to tear away from the main body of the bag, but this doesn't happen with Dakine, or at least it hasn't happened with me yet (and I fill my backpack with pretty heavy stuff!) If you are looking for a reliable bag with plenty of room for your children's schoolbooks, or you are looking for something you can use for going to work or going hiking, these backpacks are highly versatile and I use them for everything!
