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.

Price Paid: $129 at MSL

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.
