    Osprey Manta 28 Hydration Pack - 100 fl. rated4.6out of5by15.
    Rated5out of5byfromHas survived 2.5 years of abuse... love this pack!I bought this pack two and a half years ago for day hikes and quick scrambles- it's simply great! I got this pack in the small size and it fits well- something that can be hard to find if you are petite and have a short torso. The pack stays close to your body and has a low-profile, making it great for scrambling. You can wear a helmet and easily look up while wearing this pack. There is just enough room in this pack for your water, food, and 10 essentials, so don't expect this to be your only pack. I like to wear this when I'm going on a long hike with lots of elevation gain and don't feel like more "conditioning" weight is necessary. Be aware that if you are going somewhere where lots of layers and gear are required that this may not be the bag for you. You can take the rainfly out and that will free up some room in the pack but this pack really isn't meant for long trips.

    Rated5out of5byfromGreat pack!I've never owned a hydration pack before, but I can't think of anything that is wrong with that feature on this pack. its easily stored and accessible, and the water flows easily. i've run with this pack and it adjusts very snug against my back. the only problem i had was when i tried to run without a shirt. the mesh backing rubbed a small burn into my back, but any pack would probably do that. I love that the backing allows for airflow. Its a very comfortable pack. I will use this for day hikes with and without the bladder.

    Rated5out of5byfromfantastic day pack*Note I have not used the hydration system on this product yet. I used the Osprey Manta 28 for daily use during our 2 week trip to Guatemala. It was a fantastic size to fit our daily needs; LP Guatemala guide, DSLR +1 extra lens, extra layers of clothes, snacks, water bottle etc. The built in rain fly was and extra bonus when we got caught in a rain storm walking through the Tikal jungle at night after sunset! The whole two weeks of hiking I never had a 'sweaty back' that I normally get from packs. The straps and waist belt had easy adjustments to get the fit just right. I would definitely recommend this to anyone looking for a higher end day pack (this one has the extras for you), also excited to try out the hydration pack in the US (we did not want to use the tap water in Guatemala).

    Rated5out of5byfromAwesome!!!I have been using day packs for decades, from skiing, mountain biking to long hikes in the Russia. And have owned so many bags. This is by far the best to date!. It has held up well to gerneral use.

    Rated4out of5byfromLove the pack, the water bladder not soI bought this Osprey pack to replace my 20ltr Camelback RimRunner. The Osprey offered a lot more organization, comfort and simply more room. While I love this pack I am not a huge fan of the bladder. The hose does no disconnect from the bladder forcing you to remove the hose from the straps every time you need to fill or clean it. The bladder also does not have an easy way to prop it open to dry as the Camelback line does. I just ended up doing a little rigging on the internal straps and I have fit my old Camelback bladder into the Osprey pack. Couldn't be happier. Two other things I though were kind of odd if that there is no dedicated "slot" to thread the hose through the pack, you just leave it unzipped so the hose can come through. Also while I think the magnetic bite valve is cool there is no way to move it from the left to the right side of your chest as it is build into the sternum strap buckle. I guess I could always just buy an extra magnet to move it but you think they would have thought of this in the design process.

    Rated4out of5byfromPerfect for a Half Dome hikeThis was a perfect pack for my Half Dome hike this summer. Plenty of room for all the water and gear I needed for an 18-mile, 12-hour hike. My only complaint is that the plastic loop used to secure hiking poles can jut right out into your swinging arms while hiking. Very comfortable pack.

    Rated4out of5byfromGreat 30-40lb packI really like the pack overall. I just don't have enough adjustment to get it tight around my waist (size: 34 weight: 185) to support the weight. I bought the M/L to fit my 6' frame and wide shouldes better. Anyway a small blanket fixed this issue.
