The Osprey Manta 30 hydration pack combines ample volume and great carrying comfort with the latest in easy, functional hydration.

  • Osprey Hydraulics™ system sandwiches an anatomically shaped plastic sheet between a layer of nylon fabric and the reservoir back
  • Design conforms the reservoir to the back's shape even when full, resulting in a precise, stable and comfortable fit
  • HydraForm™ reservoir features a rigid spine/handle that stabilizes the water load and makes it easy to slide the reservoir into the pack
  • Rigid spine/handle and large mouth make filling and cleaning the reservoir a snap
  • BPA- and PVC-free reservoir does not retain tastes or odors and features AquaGuard™ antimicrobial formula to help prevent bacteria and mold
  • 180° pivoting on/off valve rotates in either direction for quick and easy flow control; magnetic sternum-strap buckle secures the bite valve when not in use
  • AirSpeed™ suspension incorporates a lightweight alloy frame and cross struts with a tensioned mesh back panel for support and flexibility
  • Breathable mesh and perforated, molded waffle foam at contact points on contoured shoulder straps and hipbelt enhance breathability and comfort
  • Panel-loading main compartment is spacious enough for a long day's worth of food, clothing and gear
  • Zippered top organizational pocket with key clip holds small items; zippered top pocket with soft lining helps keep sunglasses or other fragile items from getting scratched
  • Large and small stretch-woven front shove-it pockets offer quick external storage and access; integrated patch holds a blinker light (sold separately)
  • Zippered side pockets carry small items within easy reach
  • The Osprey Manta 30 hydration pack features an integrated raincover that can be deployed quickly to keep contents dry

Osprey Manta 30 Hydration Pack - 100 fl. rated4.7143out of5by7.
Rated4out of5byfromSlight squeak somewhereGreat bag however ive noticed a small squeak develop somewhere on the pack due to the suspension system. I get extremely annoyed with squeaks (replaced an old pack for that reason alone) but this one occurs seldomly and is not too loud so whatever. Also, note that the sternum clip in the front is actually a dark grey (not red as in the picture). Pockets are nice and big to carry water, jacket, bike pump, etc. The rain fly does its job. My other complaint would be the extra long straps but that could be easily adjusted with scissors

Rated5out of5byfromexcellent packThis pack is perfect for long day hikes. It carries my survival kit, first aid kit, enough food for 2, a fleece and trekking poles with plenty of room to spare. I really like the magnetic bite valve holder and hip belt pockets. For shorter hikes the pack compresses down nicely so its not getting snagged on branches or throwing off balance. The mesh back, trekking pole holder and waterproof cover are a nice touch too. Not much padding on the shoulder straps but unless you're carrying rocks around it probably won't bother you. 15lbs or so rest nicely on the hips so I have no complaints. Its pricey but I think it will last a long time. Liked it so much I bought one for my fiancé too :)

Rated4out of5byfromFantastic Hydration Day PackThis is one fantastic pack, lots of room for a smallish pack, very comfortable. I think Osprey has the best hydration bladders/valves. The magnet on the bite valve is simple but so nice. The curved mesh back keeps it off of you back to stay cooler and keeping your body heat from reservoir. I agree with all the positive comments in other posts. My only complaint is, I'm 6'5'' with a long torso and it didn't fit very well. If your 6'2'' or shorter this pack with be great. I loved this pack so much except for the length, I gave it to my son and bought am Osprey Talon 44 for myself which is longer and more adjustable.

Rated5out of5byfromloving my packI use my pack primarily for day hikes so the size of the pack is great. I usually carry my headlamp, ball cap, bug spray, hand soap and hand/foot warmers in my pack at all times. Plus my snacks and a bottle of water. Once it warms up there's enough space to put my sweater/light jacket into the pack. Love it!

Rated5out of5byfromOsprey Manta 30 Hydration Pack, 5 StarsI'm a retired Marine and I am in my Mid. 50's, and I can honestly say that I love my Osprey Manta. It wears like a glove. It's must be the internal Frame. The avg. wt. I carry is around 25 lb. and I hike anywhere from 6 to 15 miles with a Elevation gains of 2000 ft +. This pack is the best and the most comfortable pack that I have owned.
