Review: Good bag - My son used this as school bag for two years, we reordered this bag, it's sturdy, spacious and durable except for the inner compartment linings which tore. The rain cover is quite useful as well. The packaging needs improvement though, this time it was delivered without a proper packaging.
Review: Size is good - It is good and nice Though I got the wrong colour. It's very spacious and definitely works for going to school. Would recommend it if looking for space size and worth the money.
