Glen I had to google tornado tube

But yes, that might work. It certainly will make it easier to single handedly filter water even if you aren't able to back flush with it.

I did try hooking a dirty bottle to the filter instead of using the sawyer pouch but found I needed to make a small air bleed hole in the bottle because without it I needed to crush the bottle to get the water out. I just went back to using the sawyer squeeze pouch. You may want to give it a trial run before heading out.

Thanks for the tornado tube tip, jimmyb
