Here's a really innovative gear concept I haven't seen before. Gear Pods is a very unique site that ultralight backpackers should take note of. While the pre-packaged "pod" systems they sell on their site might seem on the heavy side, digging deeper, you will find a lot of great design ideas and other gear for UL backpacking. Plus, you can customize your own system. If you are like me and are engaged in other back country sports, this flexible system will appeal to you on multiple levels.
