paulflexes saidI wonder if it's compatible with the Camelbak, because that would be awesome on a long ride.
I doubt it, because the jostling might cause the pouch to explode with the pressure. Or would it blow out the bite valve? That's a reason you're not supposed to put carbonated beverages in a Camelbak.
Which raises the question, what if you handle this BeerPouch roughly? Or forget it in a hot car. Will it swell up, maybe burst?
And BTW, this basic idea has existed for centuries, only with natural materials. Ever drink wine from a Spanish bota? Fill it from a wine cask, then be on your way, light, soft & unbreakable, perfect for horseback. Or fill with water and you have a canteen.....................
