Very good water bag, but with untrustworthy cap
"I have been using this water bag as my primary water container for the past 6 years, starting with the Dromedary, tougher ones, and moving on to the DromLite system after the 2L became unavailable. In the past year, I have had several leaks due to the cap fissuring (three different caps had that issue, two over the winter and one more recently in early summer). Sadly, this issue has made me rather wary of relying on this (otherwise great) water bag. I have contacted Cascade Designs and they have assured me that this issue hasn't been reported to them, but if you have leaks with your water bag you might want to check the integrity of the cap."
