Go lighter and smarter.

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.

  • AirSpeed mesh backpanel supported by LightWire frame incorporates side vents so you don’t get bogged down by the sweaties and ridge foam to keep your back happy
  • BioStretch harness features perforated EVA foam with large holes for enhanced breathability and comfortable stretch lined with soft, breathable spacer mesh
  • Stretch sternum strap has magnetic hose clip for quick and easy access to life-sustaining water
  • Mesh-covered BioStretch built-in hip-belt transfer and stabilizes load, breathes via perforation, and features a modified, straight ErgoPull closure
  • Rugged and light 70 x 100D nylon shadow creek and 600D polyester fabrics withstand outdoor wear and tear
  • Integrated rain cover comes out when the clouds let loose
  • Ample 3-liter Hydraulics reservoir features an integral framesheet to keep water close to your body and prevent barreling, a rigid handle for easy insertion into pack, and wide-mouth cap for easy filling and cleaning
  • MPE film in reservoir ensures taste-free water and is durable enough to handle hot water
  • Hydration sleeve allows direct access via zipper for loading in a hurry
  • Zippered stretch mesh hip-belt pockets secure small, quick-access items, stretch mesh front and side pockets let you quickly stash extra gear, and zippered, embossed sunglasses pocket protects your eyewear
  • Dual side compression straps keep load lean and close to body for a stable haul
  • Helmet attachment loop gives you a spot to hang your climb, bike, or ski helmet while not in use
  • Stow-on-the-Go loops secure your trekking poles out of the way when not needed

Nice little pack

Nice little pack

Great for short day hikes - torso isn't long enough for me to comfortably hold a lot of weight but that's OK as it is a small pack and impossible to load up with more than water and a few snacks and layers anyway... but if you ask me it would be better if there were sizes for us crazy long torso people...

They've thought of everything!

  • Familiarity: I've put it through the wringer

I'm getting into my third season with this pack. After several hundred miles on the trails, it still looks and feels new.

I liked that all the main features of this line were offered on the smallest size (20L) . I'd rather have a small pack with some carabiners for extra utility than use a pack larger than I'd typically need. I can stash a extra layer or two, plenty of food, a small carton of wine, and all necessary gear. Some people may want more space for peace of mind (and they do make 2 larger sizes), but for yours truly, the 20L is the way to go.

The 3L reservoir holds more water than I could ever use, even on an 18-mile day. The magnetic nozzle holder is a great feature. However, I would recommend to Osprey to make a cap for the nozzle to keep it clean from trail dust. I've seen a small tethered cap on some European hydration packs.

I have three Osprey packs, and this one has the most impressive array of features. The ventilated straps and back panel are terrific. The integrated rain cover that tucks away out of sight is just brilliant. The hip belt adds stability when bouncing around and gives you hip pockets - not all packs of this size have them. There are loops to hold trekking poles under your arm - not very elegant, but secure and useful. The pack is lighter than you might expect, so it remains comfortable on long treks. And there are plenty of straps and loops if you like to improvise.

This pack gives me a lot of satisfaction every time I use it. I've recommended it to my friends, and now they've seen the light and are spreading the word.

Perfect day pack!

  • Familiarity: I've used it several times

I Love this pack! Just the right amount of room for all my supplies & rain jacket. The 3 liter bladder is easy fill and slides in perfectly! I love the magnetic part on the mouth piece to keep it in place while hiking and the built in rain cover is super convenient to make sure everything stays dry. I couldn't be happier!

Best Day Hike Pack

  • Familiarity: I've put it through the wringer

Have used this all around Western Washington's day hike peaks including Mt. Si, Rattlesnake Ledge, Mt. Pilchuck, and many others. I was able to fit the ten essentials with a water reservoir that is perfect for day hikes. I have also used this pack for going to the climbing gym to fit my harness, belay devices, rock shoes, and chalk bag. Anyone looking for a lightweight hiking pack, this is it.

I see that the new 20L version is 'one...
