I have been looking for something to replace a water backpack Bladder i hate messing with trying to fill those water bladders and trying to clean those water bladders..will i finally found a great replacement for a water bladder it's called a SmarTube drinking system for water bottles. Wherever you put your water bottle, in your backpack, fanny pack or the bottle holders on your turkey vest you can attach this and have water with the drink tube just like the water bladder. Check it out on Amazon..got mine today..no more heavy water bladders. Smartube drinking system..
I like that idea. I would add a hydration tube cover.

Only thing I would miss is being able to put some ice in the water.
