You can do with it whatever you want, as long as you want it to be light.


  • Lightweight
  • As many features as a full size pack


  • Durability
  • Pricepoint

It is designed to be a hyper-light pack. It does its job perfectly. You can do with it whatever you want, as long as you want it to be light. I like it, plenty of room for everything you in ultralight summer backpacking, day hikes, or a rucksack to throw emergency gear on back country bike trips.

Thoughtful design that cuts out want you don't want for the sake of keeping what you do. Gear loop very good, COMES WITH A RAIN FLY, still has two hip belt pockets that zipper = great when you bomb over the handle bars. An extranious layer of fabric here, or a pointless loop that I would remove there. Overall you're always trading one thing for lightweight and that is durability.

Osprey makes many great products and the manta 20 is another great example, from the back suspension system to the stow-and-go front pouch the manta 20 offers ample space and light weight.


Myself being a big guy at 250 lbs the pack does a great job of fitting to me with several adjustment straps to fit anyone from small frame to large frames, and while including the 3-liter reservoir it is the perfect pack for short day hikes to the overnight hike ith the ability easily carry 20 lbs of gear and with the intergrated rain cover you will be ready for whatever nature has to throw at you.

Overall price and function makes the manta 20 a must have.

Fast and light endeavors are perfect for the Osprey Manta 20.

The updated Osprey Manta 20 hydration pack combines a well-engineered hydration system with great carrying comfort to keep you hydrated and moving fast during your done-in-a-day adventures.


As you can see with the Mantra 20 Hydration Pack, Osprey thinks differently: to it, a hydration pack is a full system that not only quenches your thirst for optimal performance, but organizes your gear in a thoughtful manner. Though the smallest in the Manta series, it provides the full set of features, but in a lighter, more compact construction. It boasts the advanced HydraLock frame that makes packing your reservoir a breeze and a magnetic valve holder for quick and frequent sips. AirSpeed suspension and a BioStretch harness distribute and stabilize the load for maximum comfort, and plentiful pockets and organizing elements, including a padded sunglasses pocket and trekking pole carrier, keep everything tidy for speedy access.
