This is kind of new fangled to me... When we got rid of the little wooden kegs we carried water in and went to the little round metal canteens I thought WOW!!!! Much later learned to put surgical tubing into the CBR cap of a 2QT bladder upside down on my ruck and I was high styling... So the whole camelbak thing sounded pretty good. I picked up a surplus carrier and a excess 3l bladder. The question is.... other than water... What else is safe to put in them?
IIRC I don't think anything else is meant to be put in them. You can put other drinks in them but they must be carefully washed out afterwards. It is a pain in the ass IMO and honestly I dont know anyone who puts anything but water in them. Camelbacks are a good idea but Im not really a fan. I hardly ever used mine.
RetPara. Ive sent these to my son to use in his Camelbak. He used the ones I sent him but didnt ask for more LOL. http://www.camelbak.com/Military-Tactical/Drinks/Elixir-Bulk-Berry.aspx
You can put just about any liquid into them, but you have to really clean them out if you use anything besides water. Even using plain water you have to take care to clean the bladder and let it dry unless you are using it every day. Personally, I like mine for biking and back when I wore a uniform. Some people don't care for them. My last one is from Nalgene and I like it over Camelback, it seemed to be less susceptible to crud growing in it and I've only ever put water in mine. I carry a bottle of Gatorade on my bike and the water on my back.
Did a vodka camel back 12mile roadmarch once... Had to drink everything in your camel back and finish in 3 hrs. There was some puking towards the end (from those that had WGS ...weak gene sydrome) but everyone finished! So from personal experience I know you can put vodka and Jack Daniels in them..never really thought of putting water...hmm that may have been a better choice a few times...
Guinness! I use a viper. Water is the best option to hydrate correctly! Need to clean the bladder and dry them out well or they will stink fast from any stale water left inside.
