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.

Osprey has been working on this design for a long time, and they've finally released the animal into the wild. The Hydraulics line by Osprey features an anatomically shaped reservoir that conforms to the wearer's back for a perfect, comfortable fit. The Manta 20 pack, like the entire Hydraulics line, includes the Osprey/Nalgene reservoir which is taste and odor free, BPA and PVC free, and contains the AquaGuard anti-microbial formula to prevent bacteria and mold. Cargo space isn't affected by the reservoir either, thanks to the HydraLock frame. Not only is there a separate compartment for the reservoir, but the HydraLock frame gives it a little pressure which increases water flow and keeps the water from sloshing around. Fast and light endeavors are perfect for the Manta 20 hydration pack. Incorporating a streamlined design along with all the key features of its larger siblings, this pack is perfect for light and fast hikes, adventure racing and full day trans-alpine mountain bike rides.Features : 180deg On-Off Pivot Bite Valve HydraForm(TM) Reservoir Filling and Cleaning HydraLock(TM) Compartment Integrated Raincover - Stretch the raincover over your Manta Series pack to keep your gear dry during foul weather. Key Clip Magnetic sternum strap buckle NoScratch(TM) Top Slash Pocket Stretch Woven Front Pocket - A stretch woven front pocket with integrated blinker light patch provides quick external storage and visibility.
