Comments about Osprey MANTA AG™ 36:

Until recently I have had the model Manta 36 back and without a doubt is the most versatile backpack I've ever owned. Used for everything from commuting with a laptop, day & overnight hikes and long distance (200km+) bike rides.

It has pocket everywhere and almost everything you can think off which makes it easy to keep track of everything you might need for an unsupported long distance ride or an overnight hike.

The only real negative was that the seemed to forget that the hose for the hydration bag has to come out somewhere, and the only location was through the zipper. Not a show stopper, but given the money a little annoying.

Just recently one of the zipper broke and is hopefully going to be repaired under the Osprey warranty program. I am hoping it will be repaired and not replaced with the latest version simply much bigger.

While not noticeably any heavier, the new model is much bigger because of the new AG frame. Too big to be practical as a bag to use on cycling adventures. It looks and feels more like bag that you would use solely for overnight hiking trips and no longer the multi-purpose (1-bag-fits-all) that the old model was. While I am sure that the AG frame is excellent, I don't think you'd be looking at this bag anymore as one that you'd use to take the laptop in to the office unless you wanted people asking you "where's your tent?"

Which is real shame because the previous model was as Emmet says "Awesome". The new one... made for one purpose, which unfortunately misses the mark for many users.

Would I recommend? Absolutely if you go hiking. Otherwise search high and low to try and find the old model.

    Comments about Osprey MANTA AG™ 36:

    Being a minimalist, I don't like to fill my closets with too many backpacks. That said, it's difficult to not have at least 3 or 4. With this in mind, I bought the Manta 36 to perform daily duty as my office backpack to carry notebook, a heavy dell laptop and organize pens, etc as well as using it for day hikes with camera and tripod. Despite it's lightweight construction, it's held up well after 3 years with nary any signs of wear. The only thing that's broken on it is the magnetic sternum strap buckle and I think it broke because it got caught in the car door.
    I love all of the pockets, it makes for great organization of my on-the-go office supplies and when I travel. After years of growing accustomed to Osprey's Anti-Gravity suspension, it's hard to go back to a standard pack with it's hot and sweaty backpanel.
