Lumbar packs are great if you want to carry your bits and pieces on a hilly walk, without the hassles of a big heavy rucksack. This one by Mountainsmith has the added bonus of being made entirely from tough recycled PET (in this case plastic soda bottles). It has all the same great features of a regular top of the range lumbar pack, including several handy zip pockets, mesh bottle holders, load adjusting system, and even an optional shoulder strap to turn it into a nifty bag. It's available in black, cobalt and red, and if this 'Day pack' is too big for your requirements there's a smaller size too. US$79.95 from Reusable bags.com
