I got one of the old model year Manta 28s on clearance yesterday. My wife and I actually both got one as we both needed new day packs. The squeaking is real and it appears to be a function of weight. We took them on a short day hike this morning. She only had a full water bladder and a couple of other items. Total weight was likely only about 10-12 lbs. No squeaks. She loves it. Mine, on the other hand, had about 25-30lbs in it including the bladder. Weight appears to be a, if not the, critical factor in the squeaking. I took mine back to REI. The guy seemed very aware of the squeaking issue and seemed to confirm that weight was a major contributor. He pointed me to a couple of alternatives. One of the key items I was looking for was a separate pocket for the hydration bladder to try and minimize the chance of an accidental leak damaging my camera gear. I ended up selecting the newest version Manta 34. It's slightly larger than the 28 but, more importantly Osprey appears to have completely redesigned the suspension. The new version, rather than being S/M and M/L is one size with a clever way to adjust the straps to your torso about an inch at a time. I loaded up with the same load and took a walk on my treadmill and, so far, no squeaking. Both old and new do a great job of transferring weight onto your hips but I'd say the old Manta is slightly more comfortable. It just put the weight right on the hips so perfectly. It felt almost custom tailored. But the new version doesn't squeak, so... The new suspension seems very well thought out and, with all that same kit and the full bladder the load stays pretty much completely out of contact with my back. The ventilation is great. The pockets are pretty much the same layout as last year's Manta 28 but the organization pocket, since it's a little larger, also includes a long zippered mesh pocket with a key minder. That's a nice touch. Another change is the sternum strap. The sternum strap is now magnetic. The shape of the plastic piece that locks it in place pretty much precludes accidentally unlocking it. You have to twist slightly to get it to dislodge. It also serves as the magnet for your hydration bladder drink tube. I like this little tweak, however, I do like having a whistle that many of my other packs has on the sternum strap. It's not a big deal but it is a nice safety touch that you're not at risk of ever forgetting. I think that this is a nice evolution of this series of packs. The one thing that could still do with some improvement are the hip belt pockets. The zippers are situated, and the pockets are such an irregular shape, that it's very difficult to close them back up once you have them open. Either you take off the pack, or you get your travel partner to zip the pocket closed. Perhaps they'll get easier to close as I get more miles on this pack. In general though, I'm very impressed.

Useless mesh panel
Rich

Got this pack for the mesh ventilation. Turns out the plastic torso length adjuster blocks the top half of the mesh. Literally half the ventilation is backed by a big sheet of plastic that sits against your upper back. It's worse than a regular foam panel. In the Gregory packs the torso adjuster is sewn into the pack itself, so the mesh sits away from it, but here the adjuster is right on the mesh itself. Defeats the entire purpose.

Newly designed pack - excellent improvement

6 years ago

To begin, I have about 5 years of experience with the Manta 36 non AG version and have hiked MANY enjoyable miles with that pack. So first I would say quality is a given - it IS an Osprey and does not disappoint !! [Layout] This pack is 2 liters smaller in volume but does not seem as such, the pack is much wider, seems to have MORE room actually because of a different (I think “better”) layout. The external stretchy layer is still there but the external compression ‘pocket’ between the small organizer area and the main area is gone. This makes the main area much more spacious than the old design as I guess it encapsulates that extra room. :) Also gone is the side access panel, that let you get into the bottom of the pack easier :( So now you have a larger and wider organizer section, MUCH improved, easier accessed and well laid out. Adjustable suspension is done with a rigid panel buttoning system, very easy and simple to do. [Support and carry] The support and belt area is MUCH more padded/supportive than the original, but does not have as much as the AG version. So for the folks with the AG version, your mileage may vary - but it is a very very comfortable pack and I would have to say it is more comfortable than the original (Manta 36) that I bought back in 2015. This is important as the correct weight load should be mostly absorbed around your hip area and NOT on your shoulders. This pack is large enough that trying to just use shoulders for carry is probably going to be painful after a mile or more. This is not a ‘micro day pack’ meant for shoulders only. I found the pack to feel relatively ‘weightless’ at around 12 lbs and under, 25 lbs was extremely comfortable and I would probably not carry more than that as I never have had the need :) [Typical weight] I typically carry around 10 - 15 lbs including the following for reference: Nikon DSLR with 18-300mm lens - 3 lbs Tripod - 1 lbs Full 3 liter full reservoir - 6.6 lbs Assorted gear, FAK, leatherman, lighter, whistle etc. - 2 lbs Lunch!!! < 1lbs And this feels like nothing on about say a 10 - 15 mile hike at a moderate to leisurely pace with mild rock climbing and say maybe a 1200 - 1600 ft elevation change. Depending on the hike that might be exaggerating a little bit but you get the point :) Around 25 lbs and still comfortable but you KNOW the pack is back there LOL ;) [Modification] Actually the only mod I did was add cobra stitching to the pack handle, mostly for ease and comfort, other than that, no mods all good [Summary] So overall I am very pleased, pack works perfectly for me as a photographer and hiker, cannot really think of any major changes I would want done to it. The old pack came through many miles of desert and canyon hiking looking almost brand new, I am expecting the same of this one. Definitely do try to try it on at the store with some simulated weight, do some back bends, crawls ie. whatever you normally do on an average hike and see if it works for you ;) Anyways, hope this helps someone to make a good choice!! For reference: I am 6’3” tall, approximately 210-220 lbs with a 19”-20” torso In reasonably fit shape Happy trails !!!!!! :)

Perfect Daypack

4 years ago

My favorite for day hikes. I have been looking at getting the Manta series for the past 5-6 yrs now and when they updated to it's current line, I bought it. I wasn't a fan of the AG system in the previous version only because the waist straps weren't accommodating for my wider, bulkier frame. When I got this 34L version, I immediately became a fan for it's versatility. The pack is fairly light and I can load my typical hiking gear, food, water (like the separate compartment for the water reservoir) and sometimes my dslr camera packing cube. I really don't have to worry about loading it for a long hike or stripping it down for daily walk or casual easy hike.

Lilliputian straps a cause for concern plus...

4 years ago

I was all over the Gregory hydro pack until a kind REI associate pointed out the wonderful Osprey Manta 34. Yeah! What a great back ventilation design...and it is. The rest of the pack is, shall we say - bizarre. The hand-carrying strap is like string. When you grab the pack to haul it into the car before a hike (and it holds a lot of water so it's heavy) it's like picking up a sack of potatoes with piano wire. The chest strap is actually a magnet with some weird hooking system. My wife and I were both flummoxed trying to figure out how it opened or closed. In practice, it works quite well but again, it feels very flimsy. The teeny-weeny clip which holds the (excellent) water bladder is unreal. Never mind my fear that it's going to snap off; I actually have trouble getting it to snap together, it's that small, and I'm one of those dudes with really dextrous fingers - my wife always gives me her tiny necklaces to unravel when the microscopic links get all knotted up. Probably the worst feature is the side\hip pockets which I was dreaming of using for a GoPro (after my 15-year-old North Face pack) which are impossible to open or close once the pack is on. These are not YKK zips but some cheap alternative so unless you want to stop on the trail or take off the pack they simply won't open or close due to the shape and design here. The zippers in general are hard to use and of low quality. The good: the water bladder is great and works well in practice, the vented back is superb and it's a very comfy pack to haul around in the California mountain heat all day. This was probably a superb design 10 years ago but they kept tinkering with it, making everything micro-miniaturized and cost-cutting the zips until it is now a "could have been good" pack. Sigh.

Well-built, fully-featured versatile pack

2 years ago

My colleague and I needed burlier, durable, comfortable, versatile packs for use in rugged outdoor fieldwork hucking substantial volume and weight, weekend trips, and day-to-day cycle commuting. This bag DELIVERS. If you are looking for a minimalistic ultralight pack, this is not for you. If you what something fully featured and durable with a bombproof lifetime Osprey warranty, this is for you. This pack weighs more than my 58L Osprey Eja and Hyperlite multi-day packs, but in return it provides convenience, structure, and pockets up the wazoo, which I love. My colleague owns this Manta 34 pack while I carry the women's version, the Mira 32 which differs mainly in torso length and strap curvature around breasts. We're both happy with this expensive upgrade from school-style backpacks. My main gripe with previous Osprey packs has been the durability of the mesh pockets, which has been fixed in this iteration of packs by replacing the mesh with a smaller-pore material and a solid material near the bottom (with a hole for rainwater drainage). The pack itself is moderately water-resistant, and conveniently comes with its own high-vis, fitted pack cover, great unexpected rains and cycling visibility. I really appreciate that it comes with a hydration pouch as well that I've found easy to use and clean (w/ detachable hose and wide opening). As a bonus, I like using the hydration pouch pocket for my laptop for office use. They've included everything, from an interior keychain clip, to a hiking pole/ice axe loop, and hip-belt pockets for easy snacking. The pack carries comfortably across many uses, compressing neatly with cinching straps for light and low-volume use, and w/ external attachment points expanding mesh pockets, and a sturdy trampoline-style mesh frame and wide hip-belt for large and heavy loads. However, due to the shorter length of this pack (compared to backpacking packs), I've had a harder time getting the load to carry on the hips, over the shoulder straps. Over 1 year, I've used this as my main commuter bag, brought it on day and overnight hikes across Alaska, New Zealand, and Australia, used it as gate-checked, carry-on, and personal-item luggage, and filled it with everything from soil samples, bones, and rocks, to laptops, documents, and delicate equipment. I've scraped it past thorny branches, dropped it off cliffs, and kicked it across concrete floors. So far, it's not shown damage and has held up better than any other backpack of this size.

Excellent

I carried this pack on a 5 mile hike loaded with 20lbs the day after I bought it to see how it would do. I must say that it was an absolute joy to carry. I’m turning this one into sort of an edc/hiking pack. I like to carry something like a day pack with some essentials in it the case of an emergency (ie. first aid, knife, headlamp, space blanket, firesteel, water bottle, etc.) whatever it might be, but this pack has every bit the capacity to allow me to keep a set of hiking clothes in it also. I like that because now all my gear but my hiking boots is in one bag ready hit the trail when I want to go.

Perfect day pack

4 years ago

This is really the perfect day pack. I used it on my Mt. Kilimanjaro summit last year. It holds enough water to get through a day (8-12 hours) of hiking in warm or cold weather. It is comfortable even when loaded up, and has all of the storage I could want. It was easy to get on and off, easy to stow my poles, and didn't tire my back and shoulders. It isn't built to be carrying tents, sleeping bags, and bear cannisters. If you need all that, you surely want to go up a size. If you have a base camp or are going on daily hikes, this is going to be an ideal pack to use.

First Real Backpack

3 years ago

This was my first time owning a real backpack and I was blown away by how much better it feels to actually have the weight sitting on your hips. I use this for day hikes, carrying water and food for my girlfriend, dog, and I, and I felt like I could go all day with this pack. The materials feel nice, every single feature is usable, and the reservoir blows away anything I’ve used before. I can’t say whether this is the best option for everyone out there, or even a good one, but for someone like me who has never owned a backpack that cost more than $30, this pack is exceptional.

Great for pack for all types of hiking

3 years ago

I took this pack to Mt. Whitney for a 10 hour hike and this pack is the most comfortable pack I have ever owned. The hydration pack is a excellent and having the water tube easily accessible makes a water bottle obsolete. This has enough convenient storage areas especially the side hip storage for easy to access food made it easier to eat while hiking. And it’s so easy to store hiking sticks quickly and no worries about them sliding off the side of the mountain because they’re securely held in place. Plus, the mesh back allows your pack and back breath. I wouldn’t use any other pack.

Day pack...day hike.

6 years ago

I recently purchased the men’s Manta 34 hydration pack. I have a longer torso so I found this pack fit me best. I went for a moderate day hike (pretty steep), about 7 miles. I have had neck problems for quite some time and found the pack to be really comfortable. The pack took a lot of pressure off my neck (I had it fairly packed and hydration bladder filled). The pack felt balanced and was very comfortable. I read in some reviews that the pack was noisily, when walking. I think it has to do with the fabric of the pack rubbing against the frame. It was slightly annoying once I noticed the sound. However, the comfort of the pack, the set up of the pack itself (pockets and compartments), and how good it left my neck feeling ....I felt it was worthy of 4 stars.
