kevinlnwrote a review of Osprey Packs Manta 36 Hydration Pack - 2075-2197cu in on May 10, 2016
I have 2 hydration packs: the Osprey Manta 36 and a CamelBak Rim Runner. I originally only had the Camelbak but decided to get another hydration pack a a couple of years ago because my girlfriend kept wanting to use my CamelBak. I love my other Osprey packs so I really wanted to love this hydration pack. The magnetic clip and back frame were all appealing to me. I didn't even mind that the back frame limited the amount of storage space in the bag. I decided to pull the trigger and ordered this pack.
I immediately regretted it. The pack itself is perfectly fine, but the hydration bladder makes this pack absolutely useless. The bladder has to be closed a very specific way or else it will leak. I learned that the hard way after taking my pack out of the trunk only to find out that half of the 3 liters of water had leaked out. Since then, I have to hold the bladder upside down to find out if I have it sealed correctly or not. Do a quick google search and you'll see that plenty of people have this problem.
I had spent too much money on this pack to just throw it away or buy another one so I just kept using it. That is until the cap on the hydration bladder stopped turning. I don't know what happened, but the the blue ring around the cap started rubbing up against the cap in a certain way that causes too much friction. This makes it impossible to open or close the cap without significant effort. After this happened, I had had enough with the pack and just threw it in the garage.
I'm only writing this review now because while cleaning out the garage, I came across this pack again. I decided to clean it up and give it another go, only to get so frustrated with the non-turning cap and be reminded about why I threw it in the garage in the first place.
I've loved all Osprey packs I've owned throughout the years, but the hydration bladder makes this pack absolutely useless. Needless to say, I'm sticking with Camelbak.
