Go on, just try and find me a more fun backpack than this bad boy. The reason it's so awesome? It was designed by a over-tired five-year-old who'd just had a family bag of Skittles*
Here's some blurb from Stockholm's Nitty Gritty (who stock the bag):
Epperson Mountaineering has been producing high-quality gear made in the U.S.A for over 30 years. To this day they still make their bags out of their workshop in Libby, Montana. Experiences have taught the brand to more or less only use tried and tested outdoor fabrics such as cordura nylon and leather. In other words Epperson Mountaineering luggage are built to last but also to look smart in the process. Since the company has been around for quite a while they started out before online shops and what not. In fact they originally sold their products from the back of specialist magazines by mail order, first for a small group of specialists only through today where the brand has grown to outfit a generation of new adventurers whether it’s urban or wild, natural surroundings on the exploring agenda.
