Better than you think

I was initially skeptical of a hydration bladder that closed like a plastic baggie, but I got this based on my fondness for platypus water bottles. I'm convinced. The closure is very secure and hasn't leaked on me yet. The bite valve works well, and flow is good. The zip opening allows easy filling/drink mixing/ice cube adding and easy cleanup and drying. The 3L fits perfectly in the hydration sleeve of my Patagonia Endurance pack. This is a great hydration bladder to add to a pack.
