Last night I was very puzzled to find a dairy product type spillage near the unfortunate pocket, didn't think to look in it...was actually searching for choc-type nibbles I thought I had in the bag somewhere just now when I unzipped the pocket and BAM! MULLERRICE-SPILLAGE



The pocket was so waterproof that the yoghurt had remained undetected for over two weeks, I must have popped it in last minute for my lunch at work haha.
So if you want a decent reason to get a Knox backpack, you have it!
