    Thoughtful construction for enduring comfort.

    Osprey decked the Manta AG 36 Hydration Pack out with all the thoughtful features that grace the rest of its Manta series and gave the pack a large 36-liter size for epic day hikes and super-light overnighters. Stuff all your needs and wants into its capacious main compartment and plentiful pockets, and marvel at how comfy and light your load feels thanks to the Anti-Gravity suspension system and BioStretch harness. Tons of ventilation and padding reduce sticky sweat, and the included hydration system with a QuickConnect hose keeps your whistle wet, so you can keep on trucking from sunup to sundown.

    Jack of all trades

    • Familiarity: I've put it through the wringer

    Post TSA check, gear strewn across multiple bins, I was hastily cramming my 4 year old Patagonia pack with my clothes, climbing gear, and school stuff. Thinking I had stacked my items perfectly, I zipped my pack up and to my surprise the zipper teeth ripped out!
    My trusty pack finally bit the dust, after years of abuse hauling school supplies, climbing gear, and even skis stuff. I arrived in Vegas with my open backpack across my chest, holding it like a baby hoping the contents wouldn't spill out.
    Enter the Osprey Manta; I broke it in as a multi-pitch pack in Red Rocks, I use it daily as a school pack, and I continue to use it for climbing approaches. I really like the snug waist straps, as they take the load off my shoulders nicely.
    Id say its a great replacement pack, which will hopefully last me another 4 years.

    New favorite pack

    • Familiarity: I've used it several times

    The AG system is really something. I have used this pack for day hikes and even a quick overnighter in Olympic National Park (without water reservoir to save space). Had plenty of room for gear every trip, the rain cover kept water out, and the hip belt and back were great for distributing the weight. Water slots are very reachable when you wear the pack. Nice number of pockets and straps. Hip belt pockets are also a lifesaver, too. Cannot recommend this pack enough!

    This is my first Osprey bag and let’s just say, SOLD! I have been looking for a new day pack for quite some time. I needed a day pack that could hold, well...the kitchen sink. I am an over preparer and have three kids. Regardless that they all have their own packs, I still end up carrying some of their stuff. The Manta has almost 2100 cu in. Plenty of room for the extras. Plus, many pockets. I like having a designated spot for certain gear and gadgets. I first looked at the womens versions and I couldn’t find the perfect fit. It kept riding up on me anytime I had to bend. I am 5’ 10” so I switched to the mens sm/med and it fit perfectly. The anti-gravity system keeps the load light. The waistband keeps things in check and ventilation/padding has not given me any hot spots. Could not be happier and so glad I held out for the right choice.

    My go to pack for lighter duties

    • Familiarity: I've put it through the wringer

    I love the Anti Gravity (AG) on Osprey's packs, the breathability and comfort is fantastic. They are pricey but good.

    I have the Manta 34 AG, an ATMOS 50 AG and recently purchased an Aether 85 AG.

    The Manta is my go to pack for anything to vacation wandering, day hikes and long dog walks. I can easily carry enough water, jackets, snacks and assorted bits and pieces for the family of 4 and the dog.

    It is simply a well thought out pack and for me hits all the bases with comfort, features and the like.

    I have had it for about a year now and will say it still looks in good condition and think its long term durability appears pretty good.

    I am definitely happy I made this purchase.

    So far, so good

    • Familiarity: I've used it once or twice and have initial impressions

    Just snagged one yesterday, and the initial impression is that this bag matches my expectations from Osprey. I also own an Aether and an Elroy, and the Manta rounds out my flock nicely. Big enough for extended adventures, but can also be slimmed down should you be hauling a smaller load. Great hydration features (best in the game, IMO), amazing suspension, minimally stylish, and one of the best warranties in the industry.
    I was initially looking for something smaller, but I feel that this bag will prove to be the right choice for many years to come.

    Whats not to like!

    • Familiarity: I've used it several times

    So far I've only used this pack a few times but I'm very impressed with the design. I mainly got this pack for long day hikes, hunting for antler sheds and the occasional overnighter. I tend to always take extra gear, even on a single day hike (maybe it's just the Boy Scout in me) From carrying extra layers, snacks, a hammock, dog treats, etc, I always have plenty of room and the anti gravity system keeps the load light and comfortable.

    Perfect Size!

    • Familiarity: I've put it through the wringer

    Love this pack. It is amazing how well it disperses the weight. You can carry heavier loads and not feel like your shoulders are going to fall off. I've got a 3-year-old, so naturally, we have to take everything on the trail. This pack works great, has good organization and is comfortable. Osprey makes great packs and this is my go-to for day hiking or National Park excursions. I've even used it for hammock camping overnight, not too much room but if you pack it right you would be surprised at how much it can hold.

    Perfect Size!

    Bought it to use as a Camera Bag

    • Familiarity: I've put it through the wringer

    I've packed this bag full of camera gear and worn it all day on hikes and absolutely am astounded at how comfortable it is. Storage is outstanding and there are many pockets to hold all your gear. I love the separate zippered area for the hydration reservoir. It is easy to remove, refill, and replace. The side pockets have great access points so you can easily reach a water bottle while wearing the pack. The AG system is super comfy and works to keep the load off. Personally I would love it if Osprey made this bag out of outdry or another waterproof material...then I'd give it five more stars. Well done Osprey, well done.

    Thank you Leta! I even tried the smaller Manta for mountain biking but my helmet hit the top of the pack. Would love to see a toned down version of the AG on a mtb pack....completely hooked on the AG system.


      Took the bag on a backpacking trip through Europe, including France, Spain, and Italy. A lot of cushion, the anti-gravity makes it easier for traveling longer. I am a 5'9" and 165lbs, and I bought the M/L.


      • Familiarity: I've put it through the wringer

      This was a great purchase. Works as a great day pack or even a weekend bag. I just took it out of town for a 6 day trip and fit everything I need in it. So roomy it seems like a Mary Poppins bag! It has a lot of space, pockets and you can make good use of it all.

      I definitely looked at many bags before settling on this one. But it was the AG that sold me on this bag. So happy I got this one.

      Loving It

      • Familiarity: I've used it once or twice and have initial impressions

      I just got back from a weekend of hiking in Zion and I totally loved using my Manta 36. After 3 straight days of 6+ hour hikes, I've found it to be very light and comfortable, while being packed with great features. I haven't run into any discomfort or chafing yet. And, at 6'5", the M/L fits perfectly.

      Coming from day packs that keep with the "standard" backpack format of vertical storage, I'm enjoying having more zippers and compartments for organization. I see myself using this for many more hikes to come this summer.

      I'll make sure to update this with more details as I get more experience using it.
