Do you need a bag that will outlive you? Then look no further than the Blackhole 25L Backpack . My morbidity asides there is a lot of truth in that statement. The bag has been constructed from a waterproof polyester that can take all the Scottish rain that can be battered against it. Patagonia haven\'t just stopped at making it invincible though, the bag is also incredibly useful. This is due to the bag housing a 15\" Laptop sleeve plus having a huge amount of space for whatever you might want to cram inside it!
