What customers say about "Key Specs"
Osprey Manta AG 36 Hydration Pack
  • I love that the rain cover and water reservoir were included. I easily drink water whenever I need it. I used the rain cover, and it was easy and effective.
  • The compartments are good, including the spot to stuff my jacket and the clip for my car key. I like that the weight sits on my hips instead of my shoulders.
  • Product is extremely comfortable, and fit a wide range of torsos. Nice and lightweight, and durable.
  • Really comfortable bag with very well designed pockets. The weight is well distributed on your waist. This bag can swallow tons of gear without a problem and keeps it organized.
  • This pack is extremely comfortable. I like the holders for water bottles and space for plenty of gear.
  • The hip belt is great but the pockets are kind far back on the belt so it is hard to open and close them with the backpack on. The pockets are not all that big.
Osprey Stratos 36 Men's Hiking Backpack
  • Surprising amount of space can handle a weekend trip if packing light. Very comfortable and included rain cover is an awesome bonus.
  • This is a nice tactical bag which is lightweight, fits carry on size and is very comfortable to carry even in heavy loads.
  • Looks like it is well made, has quality material, feels great on my back and enough room for all my stuff plus kids for day hikes.
  • This pack is the perfect size for 3 seasons of hiking (Winter hiking I use my slightly bigger packs as I need more space for a down jacket and snow shoes, spikes, and a butt sled).
  • The hip belt fits and feels really nice and comfortable. The belt pockets provide me with enough room for all necessary stuff.
  • I just cannot pass the fact that it does not have a stretch mesh in the back. It's something you don't think about until you are in the field.

What customers say about "Features"
Osprey Manta AG 36 Hydration Pack
  • The anti-gravity hip straps and shoulder straps are extremely helpful, it did not seem heavy nor became uncomfortable during long hikes.
  • It is a great pack and i use it all the time. The rain cover is amazing, It is tough, and is easy cleaned.
  • I really like the included flap top hydration bladder which uses the magnetic valve to keep the tube in place.
  • The magnetic storage for the bite valve is genius. It makes taking the valve from stored to in your mouth incredibly easy.
  • The large size is taller than a backpack and has several easy stash pockets. The water bladder is critical for long hot days outside and the back panel vents well.
  • It has one thing this is very wrong. It creaks which gets very annoying when you are walking in the woods it is almost unbearable.
Osprey Stratos 36 Men's Hiking Backpack
  • It has a comfortable and breathable mesh back that is essential for long hikes in the summer. The pocket layout is both practical for storing items of all sizes and are conveniently placed.
  • This pack comes with an attached rain cover in its own compartment, easy to put on and put away.
  • Love the vertical zip pocket, side pockets, mesh pocket inside the pocketed top, the rain cover pocket, the "sleeping bag compartment," and the hip belt pockets.
  • The reason I love this pack is the comfort of the back. The straps are so comfortable, and the mesh back keeps me cool.
  • It is well-built, roomy, full of smart pockets, and designed by geniuses. The back panel mesh is tight enough to keep the pack close to you while providing excellent ventilation.
  • The frame is designed to sit off of your back to provide airflow. For me, the top of the pack angles too far away from my shoulders making it feel very uncomfortable with weight added.
