Review on Stay Hydrated on the Go with Source Hydration Bladder - 3L Water Bladder with High Flow Storm Valve and Hydration Technology Advantages by Tylin Meyer

I have been using these cylinders for a couple of years now and have had no problems not caused by abuse. The material is thick enough and the wide opening at the top makes cleaning so easy that you have no excuse not to clean it. One day I slipped on the trail and landed on my Rush pack that had one of these bladders in it, only to notice some leakage around the joint at the bottom of the bladder was sweating. I'm not a short guy (over 6ft and about 250lbs) so I was surprised it didn't explode. I replaced that bladder with a new one anyway, but I used the old one to make a gravity water filter with Sawyer. mini and collar. It works REALLY well for that, and it doesn't matter if there's a little leaking around the clutch. --- Overall I really like them and I RECOMMEND them to my friends.
