Review on Stay Hydrated On-The-Go With HydraPak Seeker Collapsible Water Storage - Safe, Portable And Ideal For Camping by Ryan Cornelison

This is my third hydrapak bag. I have been using them for about 4 years and haven't had any leaks. The big ones are great if you're carrying in water to a dry campsite. Or if you just want to be able to store filtered water once you get there. They also work great with the katadyn be free filters. Though remember to squeeze slowly, because as tough as these bags are if you put too much pressure on them too quickly they might still spring a leak.
