Review: Perfect - Way better than any others - I bought a couple of different baldders. Offbrand and name brand. They all tasted like chemicals/plastic. Disgusting. I have a Platypus water filtration set and really like it so I thought Id try this. It's fantastic. I'm not sure how people are complaining about flow rate. They probably don't have the valve open correctly. Or it's pinched. Flow rate - Fantastic Taste - Very minimal that went away after a couple of uses. Leaks - None at all Ease of filling - Very easy to fill while left in my bag. Ease of cleaning - Can't get my hand all the way down, but I can't in any other bladder either. The mouth opens wide enough that cleaning and drying is easy. Bit valve - Doesn't leak. Allows good flow. Comfortable to bite on/use. Sturdy. Overall there really isn't anything that I DONT like about it. A hose cover wouldn't have hurt my feelings, but not a big deal. I guess the one thing I don't like is the price. Plastic tube, welded plastic baldder, and a bite valve can't cost more than a few bucks to make in bulk. Almost $40 retail is a hell of a profit margin and does rub my sensibilities a bit wrong. But compared to similar options at the same price point... I'd pay it again.
Review: Perfect. - It has a great flow, it's very durable. It's easy to clean and fill. I throw it in the freezer overnight a lot and haven't had any problems. No leaks. I just wish there was a backpack specifically designed for it...

### ⭐⭐⭐⭐⭐ Extremely happy customer!
*by A***R on October 4, 2019*

I have used Camelbak hydration bladders in the past and so I was hesitant to change brands. To be honest, after trying both, I much rather prefer this pack by Platypus for these reasons: 1) Absolutely NO plastic taste on the first use, not even after the water sat in it for a few hours. Hallelujah! The Camelbak has always had an off taste to me. 2) The zipper on the top (vs the circle on the front of the Camelbak) makes filling a breeze, and refilling even more of a breeze. One simply has to open the top instead of digging into the pack to find the circle twist cap! 3) I found the bite valve bigger and easier to use. 4) Since the opening is large and on the top, I found it much easier to clean and also to dry--no lip to catch water like the Camelbak (from the circle twist opening.) 5) Once again, NO PLASTIC TASTE!!! This hydration bladder exceeded every expectation that I had. I used it for an 8 hour hike, refilled it once, and had no issues. It is well made, super easy to clean, and I cannot praise the easy to use design enough. I have a Flashpack 18 from REI and it fit perfectly inside. I highly recommend!
