The only gotcha on the no name Packs is that they usually have a very small resovoir opening, Usually just enough to get a faucet into the opening. Now with the Camelbacks they have Wide mouth openings so you can get Ice and any Powders into the the bladder easily. If that is not a big deal to you and you plan ahead and freeze half the liquid the night before then the No Name might be OK for you. I 'm never that organized so it wouldn't work for me.
