Best hydration pack out there
Love the hydration system easy in/out. Easily connect different size bladders without changing the hose/byte valve. Rain cover is awesome. Storage is awesome. The pack itself is surprisingly light. The mesh separator and frame make 20-30 lb load feel light. The byte valve hose magnet is great. The harness loops will easily fit a smartphone belt hook holster.
Not so great:
I got the color blue and it gets dirty pretty easily. The front pockets are difficult to open and too small.

Closer to perfect then most companies
First off, this is a great, well thought out pack that is close to perfect! The adjustability of the harness insure the best possible fit regardless of the users shape and size. The way the anti gravity suspension system fits on your back, I could actually feel a cool breeze between my back and the pack as I climbed up a steep hill. This was wonderful and a great way to disperse the back sweat! I was also very impressed that it came with a rain fly, which almost no one provides with a pack!

The few things I would change, are small things that would make it perfect and warrant the high price tag for a hydration pack and I feel the price is high!

I am not a fan of the side entry to the outer pocket. For whatever reason they decided the smaller size (most likely to be chosen for a day hike) gets the side entry pocket, while the larger capacity one gets the more traditional rainbow type zipper entry. I could probably get use to the pocket entry, if within it, in was more compartpinalised. Everything seems to flop around in the one large opening.

I love the idea of the magnet on the bite piece for the hydration bladder, but the magnet used just isn't good enough. They should have used a rare earth magnet or something of similar quality.

Osprey packs aren't the lightest minimalist daypacks, but they are solid packs with the best warranty out there. With that being said, If you're not going to make it super light, why not add a little more padding to the waist belt.

The waist belt pockets still need to be push forward more, so you don't feel like you're at the Chiropractor when you twist to close it with two hands!

The trampoline is EPIC!
I finally found a pack that fits, and the hydration design is very functional, well thought out. This is a high quality pack, worth the cost. The trampoline is EPIC, that alone is a selling point for me. I fits onto my back correctly with the weight distributed better than my other packs. I have used 4-5 other packs over the years and the Manta 24 is by far the best! The hip belt is comfortable. The shoulder straps are well padded. The magnetic chest strap is a nice touch. By the way, my wife loves her Mira 22.

Great pack, but too large.
I have hiked 60 miles with this pack the last 5 days (14 miles being the longest). The best feature on this pack is the suspened back panel keeping it away from your back and providing great venelation. Osprey needs more of this style pack. The worst feature is the overall weight and size. This pack needs to be about an 16 to 18 liter with the same susupension and hip belt. If it could be slimmed down 1 pound, it would be the best full or half day hikng pack ever constructed. It has plenty of ways to attach gear, and is narrow in width for tight spots, but when hiking at higher altitudes weight counts. I cut my body weight and gear list to cut weight and they could cut some weight from this pack as well.

Everything I need in a Daypack!
Bought this great pack a while ago and haven't had an issue with anything! Really impressed (as always) with the quality and attention to detail. The magnetic sternum clip that supports the built in hydro pack mouthpiece is a nice touch and becomes second nature to use on the trail.

Bring back the old model manta!
Ill start by saying there is nothing wrong with the current pack, except it is too large compared to the old one. I have the older model and it is the perfect pack. I use it primarily for bikepacking. It is small enough to feel secure on rough singletrack and big enough to carry part of my gear on week long trips. None of the other bike specific packs have the built in mesh frame and hip pockets. I wore this one out so my wife bought me the current pack.... and its way to big to use on a bike. Its more like a small backpacking pack. Its a great pack but not for my uses. Now there is no pack in the osprey lineup that fills the void.

Great Daypack, but...
Already on sale?? This is a well designed, well executed DayPack with nice features. It's suspension is adjustable for best comfort for a range of body types. The mesh back panel allows air circulation which is wonderful on hot days. The hydration system needs tweaking because part of the water tube is permanately attached to the bag & can't be cleaned. This means liquid stays in the tube & presents a nice culture medium for fermenting bacteria. Recommend with reservations.
