"So my first hydration pack I received from an Army Navy surplus store. It was about 20-30 bucks and it was of civilian make. My water tasted like plastic gel, and after using it a number of times, it DID feel like I could suck a golf ball through a garden hose.
Enter Condor. Condor I have to say, makes amazing stuff. The hydration came in, hose detached, but in perfect condition. Filled the pack with water without cleaning it or anything, tasted the water and there was very minimal gel, plastic taste.
Though, when the bladder is just about empty, it will collapse to the bottom of the pack, but the tube shud remained unaffected as it is connected to the bottom anyways. Great pack."
