Hi Eric,
Just wanted to let you know that I just got back from a trip from Denver to Deadhorse, Alaska and back. I used your large expedition tank bag on my VStrom 1000. It worked flawlessly. I know you say it is not "truly waterproof" but it is as close as it gets, short of a zip-lock. It held everything, including a camelbak bladder with the hose hanging out. I never got so much as a drip in the bag. Also, it is very easy to move for fuel ups.
Thanks again for a great product!
