clean tasting water, at last!!

Ahhhh, finally water that tastes like water. The stock hydration reservoirs that come with packs these days make water taste horrible. I'd be willing to pay more up front to a company like Patagonia if they used a Platypus BPA/BPS free reservoir in all the packs they sell. Why not? Sounds like a good partnership to me. It's better for our health and better for the environment. Most stock reservoirs make water taste so horrible that I'm sure they are often landfilled. Let's push backpack companies to give us more environmentally friendly and safer water reservoirs at the point of purchase!

Nice while it lasted.

Familiarity:: I returned this product before using it

Bought this to replace an older Platypus Big Zip reservoir. The higher flow rate of the drinking tube is nice. Unfortunately, the internal divider broke in half after about 10 days of use on the JMT. I think the harder plastic of the new design is more prone to fatigue failure. It still holds water but it has the profile of a foot ball. I contacted Platypus over 6 weeks ago but no reply.

I loved it at first - but leaking issue

Familiarity:: I've put it through the wringer
Weight:: 175

I've used this bladder a ton and loved it initially - SUPER easy to fill with water and lock into place using the zip method. It also didn't taint the taste of the water nearly as much as some other reservoirs I've tried. But after a few uses, the mouthpiece started leaking - nothing dramatic, but just a small dribble. It lessens when the valve is shut, but opening and closing it all the time actually isn't that easy nor is it convenient. I went online and sadly discovered on other sites besides Backcountry that this is a common issue with their valves. Bummer! My buddy has an Osprey bladder that uses a similar zip-full technology but has never had an issue with leaks, so I'm going to try that.
