Careful construction, clearly designed by people who hike.

Osprey decked out the Mantra 30 Hydration Pack with all the thoughtful features that grace the rest of its Mantra series, and built the pack in a large 30-liter size for epic day hikes and super-lightweight overnighters. An included 3-liter water reservoir holds all the water you need for a big day, and the straw rests on a magnet at the sternum for easy access. A rotating bite valve makes it simple to reach down and guzzle some H20.

Gotta Love Osprey

  • Familiarity: I've put it through the wringer

I have an Osprey for long backpacking trips and I was wanting something that I could use for mountain biking. This is my new favorite pack. I was able to pack enough stuff in it to use it for a trip I had to take for work. Three days worth of clothes, toiletries, etc... I really don't have anything bad to say. It does exactly what it says it does.

not much capacity

This is a pretty deceptive 30L pack. because of all of the small pockets and divisions it really doesn't hold as much as other 30L, or even 20L packs! There is a huge curve inside to allow for the hydration system that makes anything angular (books, computers, notebooks, etc) impractical to carry around. Biking to work I can just barely squeeze in my lunch, a change of clothes and my small laptop- forget about the hydration bladder- instead of filling the space left by the mesh system in the back, the full bladder takes up space in the actual packing space. It's too bad because the pack would probably be perfect if the packing space inside wasn't so arched. I like the built in rain cover (again- it takes up a surprising amount of space when stowed) and I love the hydration pack, overall it has nice details, but it just doesn't have a lot of packing space

Great Pack!

Very roomy day pack, could almost pull off as an overnight pack. Comes with a bladder. Has great use of storage/pockets. The outside pouch extends so you can pack more items. Love it

Great all around day pack.

Great pack, I use it all the time. Has room for all my emergency/survival gear and raingear for me. Great place for my camera for quick use. I recommend this pack.

I bought this pack in 2011, and later this year I will be going to climb Mt Kilimanjaro. The company I am going with recommends a Day rucksack (30 – 45 litre capacity) - waterproof or with waterproof cover and able to carry about 6kg of weight.

This bag is on the smaller end of that number. I am 6'3", 220 lbs. Would this bag be suitable, or do I need to find something else?

Responded on

I'd say get a bigger bag. While you could squeak it out with this bag if you had the ultra-lightest weight gear, but even so, being a bigger guy, your "ultralight gear" would still be the larger sizes and take up more space.. You'll appreciate the added space a 38-45L pack will gain you but more importantly, you'll appreciate a better carry as well.

Plus, you can use the reservoir from your Manta in this new pack just fine--if you get the 3 magnet kit that fix on sternum straps offered by Osprey, you can even use the magnet function on the bite valve...

How is everyone sizing this pack up? Osprey doesn't have it listed under their sizing guide.... My measurements are 18.5 x 34.

Responded on

I think you are right on the borderline between the sizing. You would probably be ok with the S/M but you could get away with either size IMO.

Nice design with a couple of issues

I like this pack for many reasons but there are a couple of things that bother me. The suspension system is a little heavy and it takes up space in the pack. Also, the bottom of the suspension frame sits right on the waist of my shorts and pushes them down a little bit. It is surprisingly annoying and I am often needing to pull my shorts up.
I use this pack for mountain biking and the pockets and organization compartments are almost perfect for keeping things in their place.
I LOVE the waist belt pockets. They are perfect for a cell phone/small camera and energy bars. You can easily pull out your camera for those quick nature shots without all of the fuss of taking off your whole pack. The hipbelt pockets also promote staying fueled because it is so easy to access a gel shot, or a quick bite of an energy bar.

Great Daypack and Features

I gave it 5 stars as I love this pack. As a naturalist and docent, I need a pack that is comfortable for a variety of hikes and outings. Scout hikes, nature interpretive hikes, or just a hour or two walk on the trails by the house. It needed to not only perform well, but hold a bit more that I would alone (extra first aid, food and water for others). It does that and more.

Love the mag feature to hold the hose, mouthpiece is holding up well and the bladder system works very well. More pockets than I know what to do with... Materials seem top notch and the Osprey guarantee hopefully will never be tested.

The only gripe I have, and it is minor is the ability to fill the bladder. Due to the stiff back of the system, getting it under the fridges water outlet is impossible so I need to fill a container or pitcher and fill the bladder. This is not an issue anywhere else (sink, pump, etc) and only on my fridge, Camelback bladder is flexible so it works there.

I go between this pack and my Camelback Fourteener that has less pockets, but the bladder system, mesh back panel (cooler) and straps that seem to breathe a bit better (Camelbacks are thicker/more foam). In addition I had to sew in a tag to "hang" the Camelback bladder from as it collapses in the pack if not fully loaded. However I do prefer the Camelbak strap around the waist (wider) as well as the cinch system.

Cant go wrong with either so I have them both... the Osprey however wins most of the outings.

Osprey Manta 30

I have owned the M/L Osprey Manta 30 hydration pack for two years and it has served me well. I've worn it on runs, mountain biking, and too many hikes to mention. This pack is perfectly sized, not too small or too large/bulky; it's just right! The pack is very stable and comfortable, even on long hikes or quick movement. It's definitely a day pack, but it can be cinched down to decrease bulk when you're packing light and need it mostly for hydration.

The ventilation system works very well and keeps the pack itself off of your back preventing hot spots. I recently wore this to the summit of Long's Peak and even after 16 hours of movement, I had no soreness or chaffing caused by the Manta.

The materials used in construction are light, dry quickly, and seem to be pretty resistant to abrasion by rocks, tree bark, etc. Several times I've scuffed up against these items when biking in particular and see no damage to the exterior of the Manta. With that said the waist strap is abrasive to your clothing and will cause damage to the front of those expensive moisture wicking shirts.

The built in rain cover has come in quite handy and is one less thing to remember when packing!

My only complaint is that last year when hiking in the mountains, I attempted to secure trekking poles in the stowing system on the pack. The whole assembly came completely undone, and in the cold I had to re-route stubborn ass elastic string... which sucked badly.

Would I recommend this pack? Absolutely. I found myself on this site to order one for my wife as a gift. :)

Awesome Pack!

Used this pack on my recent trip hiking the Rockies. Held everything I needed with ease and I was able to carry enough to handle the rapidly changing weather at the higher elevations. After 30 miles over 3 days, I had no soreness or stiffness in my shoulders. The suspension system and air vents made it feel like nothing was even there. The 3L reservoir held ample water and was easy to re-fill even with the pack filled with gear. Overall, I'm thrilled with my purchase.

Great Design

This is clearly a pack designed by someone who uses packs regularly. The fit is great and the mesh back really does hold the bulk of the pack away from your back so air flows and you stay relatively dry. Excellent pocketing, this bag holds a ton of gear and it's easy to get to. Compression works well. The bladder is by far the best one I've ever used. My only suggestions would be a bit more bulk to the waist belt.

I bought my Manta 30 about 3 months ago now and since then I have pretty much been looking for any excuse to use it. I know it sounds a bit sad but this bag is awesome! I took it on a 21km hike recently through thick Australian bush and it took every thing that me and nature threw at it including very heavy rain. It hugged to me like I was born with it on. If you are umming and arring weather to get an Osprey pack with hydration JUST GET IT! Its works amazing and if you do not require it for some things it is easily removed. The over all design and quality of the bag is 5 star and is worth every sent you pay, and I will leave it at that before I sound like too much of a bag obsessed freak!

Does anybody know if this will pass carry on baggage requirements?

Best Answer Responded on


This will definitely work. In fact, it will probably fit comfortable under the seat in front of you, allowing you to bring an additional carry-on =)

Happy trails!

No good - back is too stiff and doesn't move well with body motion.

Loving the Osprey Manta 30

I do a lot of day hiking in Sedona Az and a light pack is essential especially in hot weather. I love the mechanics of the hydration system, so easy to insert in the pack. Even when bushwacking, I hardly notice I'm wearing a backpack!

I wear the small/medium frame. It would be great if there was an extra small frame and padded shoulders.The frame is a bit large for a women.

I bought the Manta 20 for short hikes.

I'm definitely an Osprey fan!!!

Awesome Pack!!

So I love my new Manta, I got it for a day bag / laptop backpack so I can use it for work, travel, hiking, etc. It fits my 13inch screen (9 "x 12.5" total size of outside of laptop) but it does so with it bulging out on the sides slightly. If you are looking for an ideal bag for a laptop, I would go with the Stratos 34 or the Aurora 35, I have not used either one yet, but I saw both at a tradeshow and have been meaning to buy one for my regular work/travel backpack, and switch my Manta to more of a day hiking/hydration pack, but it works well now for everything. I love the included rain cover and hydration bladder and air suspension to keep my back ventilated. I travel around the world with this bag, 3 continents and 5 countries so far.

Great pack

I have been using the Manta 30 all summer replacing my old Stratos for day hikes in the Rockies. Even after a long dayhike it still feels comfortable.
Pros: Light internal frame. Fits comfortably and breathable. Raincover included. Compresses easily if it's not full using the straps. Lots of pockets to keep things organized. You don't have to bite hard at all to drink out of the hydraForm reservoir, locks easily, my water always tastes great and there are no smells.
Cons: Stretch sternum strap loosens too easily for me and I have to constantly readjust it. I love the concept of the hydration bladder, but it's hard to clean and if the cap isn't on right it will leak easily. Hip pockets could be a little bigger. No emergency whistle on the sternum strap buckle.
Overall I am really happy with the Manta 30 and it is a great purchase.
