(Well I royally screwed up my first attempt to create this thread, so here it is again--readable, this time. Sorry)
At the request of BillF in the Cuben Fiber thread, I have put together some photos and text describing my 16.2 oz external frame backpack.
It has a cuben fiber bag, carries 40 lbs comfortably, transferring nearly all the weight to my waist, and is hopefully going to get me from Mexico to Canada starting on May 8.
Comments/questions/suggestions are welcome, but as I hit the trail real soon, you may have to wait five months for an answer.
Vick: you see any sources of supply that you like, feel free to add them to your thread...
