The Osprey Manta AG 28 Pack is a hiking pack for exploring the wilderness on done-in-a-day adventures. It all starts with comfort thanks to the Anti-Gravity suspension system.

Whatever you've stuffed into the pack, from extra layers, lunch and your headlamp to the included Hydraulics™ LT 2.5L reservoir, it'll all carry easily on your back. There's even an included raincover, because you never know when the rain may come.

Osprey Anti-Gravity

Osprey Anti-Gravity
Using Osprey's peripheral suspension design this lightweight, body contouring, three dimensional suspension literally allows the wearer to move as if they don’t have a pack on. Seamless suspended mesh from the shoulder blades to the lumbar and even into the hipbelt region disperses and balances the load like nothing ever has before.

Osprey Peripheral Frame

Osprey Peripheral Frame
Peripheral frame was a departure from the norm many years ago and it’s still the foundation of our gear hauling packs. A wire frame runs along the outside of the backpanel directly connecting the upper load lifters and the central core of the pack to the hipbelt to transition and spread the load. Allowing natural torsional movement, effective adjustable torsos, and different load range and backpanel builds makes this suspension design truly innovative.

Rated 5 out of 5 by from My Second I'm awaiting my second Mantra. I purchased my first 2 years ago and it has been through the ringer. I run commute from 5-10 miles per day, rain or shine, hot or cold. I've climbed mountains or just long trails on day hikes. This pack has carried quite a bit in its day. I'm retiring the original as the fabric is starting to show wear from this extreme abuse, but my order is in for my next one. I'll still use this original, just not as roughly as in the past, there are many years left in the pack. Love the design, weight, fit and comfort. You rarely even notice you have the pack on.

Rated 4 out of 5 by from Good.... but one kind of annoying feature. I use this for travel, commute and hiking. To be honest, its a great pack... but i do have one complaint: the hip belt. The hip belt is pretty rigid, and i dont need it all the time. Im a larger guy (6'2", 240lbs). The hip belt naturally is designed for a more... compact person.... than me. Its good enough for hikes, but during commuting i dont need a hip belt. The foam makes it incredibly thick and, most importantly, impossible to get out of the way when they aren't needed if i could remove the foam or get the hip packs out of the way this pack would go from a 4 start to a 5 star

Rated 5 out of 5 by from Great Pack but didnt like the bite valve. Bought this pack for my Mount Whitney summit. I shopped various other Osprey packs and other brands and this was the most comfortable, had the best strap system and the best storage. Wore it on 3 training hikes and for Whitney. The pack sat with perfect balance on my shoulders and hips. The side hip pockets were great for GU and other snacks. I was able to get one bladder in the designated pocket and another in the main compartment and still had room for extra clothes and food. My only complaint is the bladder that came with it. Not only is 2.5L a little too small for a long hike, but the bite valve is restrictive. I swapped it out and used 2 Camelback bladders I already had. Only problem now is that I need to find more long hikes so I can use this cool pack.

Rated 4 out of 5 by from Excellent size and fit just one small issue After searching any reviews and even buying and returning some other packs I settled on the Manta AG. Lightweight, good colour (green stops it looking so filthy) super adjustable and very breathable. I am using it on my hike across Israel so breathability was most important. Also the size is super perfect for a multi day hike or just as a day pack. So many pockets and compartments to store my items. I manage to fill it to the brim and still seem to have some wiggle room for extras. My one and only nitpick with it is that the hip straps are very solid and don't bend so much so when you place the bag on the floor, if you have loaded it from heavy it will always fall forwards. I am hoping that after much use the straps will loosen a little but I guess this is part of the design. But if you do not mind resting your bag against something to keep it upright, again not a huge issue but does get annoying at times, then this bag is perfect.

What size pack would be best for me? I am 5'7" and 160 pounds. Bob

Asked by: Bob W
Hey there Bob! Thanks for reaching out to us! Now, to answer this question, we need to get down to the nitty gritty, Bob. You know what I'm talking about. I'm talking about your torso length. For this item, we have two sizes: the S/M which will fit a 16-19" in torso and the M/L which will fit an 18-21" torso. You may be wondering "Brah...how do i measure my torso??" Glad you asked! HOW TO MEASURE TORSO LENGTH: • Start at the iliac crest, which is the top of the hipbones on the side of your body. These act like a shelf for supporting a pack hipbelt. • From this level on your spine, measure to the C7 vertebrae, the knobby bone at the base of your neck when you put your head down. • Make sure you keep your back as straight as possible while measuring. • This torso measurement determines what size Osprey pack you should carry. Refer to the size charts above to find your ideal size. • If you are in between sizes, it is ideal to try them both on before ordering. Hope this helps you out!!! Hugsies.

OSPREY MEASUREMENT GUIDE

Please note that the info provided above refers to the torso size each pack will fit, and NOT any dimensions of the pack. Below are some steps for how to get your torso length. You should probably have someone help take this measurement for you so it is accurate. And they might accidentally touch your butt.

HOW TO MEASURE TORSO LENGTH:
• Start at the iliac crest, which is the top of the hipbones on the side of your body. These act like a shelf for supporting a pack hipbelt.
• From this level on your spine, measure to the C7 vertebrae, the knobby bone at the base of your neck when you put your head down.
• Make sure you keep your back as straight as possible while measuring.
• This torso measurement determines what size Osprey pack you should carry. Refer to the size charts above to find your ideal size.
• If you are in between sizes, it is ideal to try them both on before ordering.

HOW TO MEASURE HIPBELT SIZE:
• Measure around your hips at your iliac crest, NOT your waist.
• A properly fitted hipbelt rides centered over the hipbones and needs to be very snug.
• The padded portion should wrap well around your hips, leaving a gap of 3 to 6 inches between the tips of the both hip pads when securely tightened.
• Refer to the Hipbelts size chart above to help determine your ideal Osprey pack size, but again, your torso length is what should determine your pack size, NOT the hipbelt.

- + Warranty Info

ALL MIGHTY GUARANTEE - Osprey's Lifetime Warranty

When Osprey celebrated their 35th anniversary in 2009 they launched The Osprey All Mighty Guarantee. What that means to you is ANY Osprey product purchased at ANY time is covered. Any product, any reason, any era - the all encompassing Osprey lifetime warranty ensures their dedication to superior design, craftsmanship and quality of their products is backed up by their actions to replace or repair a pack so it lasts a lifetime. Or two.

Here are some details.... Osprey will repair for any reason, free of charge, any damage or defect in their products, whether it was purchased back in 1974, or ordered right now from this site. If they are unable to perform a functional repair on your pack, they will happily replace it. Osprey proudly stands behind the All Mighty Guarantee, so much so that it bears the signature of company founder and head designer, Mike Pfotenhauer.

Some Osprey All Mighty Guarantee FAQs:

What do I do if my Osprey pack needs to be repaired?
If you live in the United States and need a repair done on your Osprey pack, you will first need to obtain a Return Authorization number. You can do this by reaching their Returns Department at 866-314-3130, or using the information that is provided with a new Osprey pack.

What do I do if I just need a replacement pack part like a buckle?
Give Osprey a call at 866-314-3130 and they will take care of you.

How long will it take?
You can tell Osprey you need the pack returned by a certain date when you request a Return Authorization number, and they will do their absolute best to meet that deadline.

What if my pack is super dirty and stinks?
Clean it before you send it to Osprey to get repaired. The real reason is that there is a law that says if your gear is too dirty or odiferous (smelly), Osprey is not allowed to repair it and will just return it to you.

Do I have to pay for shipping?
A little bit. You are responsible for the cost of shipping the pack to Osprey, and they will pay shipping to return the pack via UPS or FedEx. Osprey cannot be held responsible if packages get lost in transit, so make sure you get a tracking number when you ship your pack out. Also, if you use expedited shipping be sure to let Osprey know (866-314-3130). They, in turn, will give your pack priority processing and return it using a similar expedited shipping method.

Do I have to register my pack to take advantage of this incredible guarantee, and/or need to be the original owner of my Osprey pack?
No! Osprey's All Mighty Guarantee is truly ALL MIGHTY. If you own an Osprey pack that needs to be repaired they will repair or replace it.

JUST A HEADS UP: If your Osprey product is not repairable and is replaced, the original product will not be returned to you. They will try really really hard to repair your pack, but if they are unable to make a functional repair, they will replace it. For products that are no longer in production you will be contacted by Osprey to discuss replacement options.

All good answers. So what is NOT covered?
• Osprey program packs or any Osprey pack used by outdoor programs are ONLY covered under Osprey's Program Pack Warranty, NOT AMG.
• Size and/or fit issues. Make sure you buy a pack that fits. Check out the size guide on Osprey product pages for more info.
• Personal preferences like colors you don't like, style of the pack, or not enough/too much room in your pack. Check the product description, features, specifications, and size guide to make sure you are ordering the right pack for you.
• Third party Repairs or replacements. Send your Osprey pack to Osprey and Osprey only to get fixed. Easy as that. And don't try fixing things yourself.
• Cosmetic wear and tear including any reasonable aging of your pack that affects only the appearance and not the function of your pack. Be proud of those scars!
• B.A.M.G. (Before All Mighty Guarantee) Repair Work. The All Mighty Guarantee applies only to repairs requested on or after January 1, 2009.
• A Osprey Hydraulics reservoir is covered by a limited 1-year warranty, which is the reasonable lifespan of a reservoir. Pouring and storing of warm/hot or boiling water in your reservoir WILL VOID your warranty, so don't do that. Reservoirs are NOT designed to contain or handle liquids at temperature.
