Very ergonomic pack. Fits well and doesn't shift. The zippers are all very sturdy. Osprey did a great job making this durable. I would recommend this pack to a mt biker, trail runner, day hiker etc...


  • Lightweight
  • Roomy
  • Durable


  • Straps are a bit lengthy

Love the shell in the hidden pocket to keep the rain out. The mid pocket seems very water resistant and it fits a good amount of gear.  I mountain bike and trail run with this bad boy. Made a good cushion when falling off my bike.

Another thing Osprey did was make a fantastic hydration system. The bite valve is money and easy to clean and the h20 pack is durable and keeps the water from sloshing around. 

The straps are easy to adjust and it genuinely fits well. 


This daypack is the perfect balance between weight…

This daypack is the perfect balance between weight and capacity in a well designed product made from quality materials. This model continues the tradition that the Osprey name has built.


  • Lightweight
  • Well designed
  • Quality fabrics and buckles
  • Good capacity
  • Good ventilation
  • Durable

This daypack fits me well and doesn't feel like a burden even on long hikes. I have used it in urban settings as well as backcountry and I keep going back to it as my go-to daypack when I want to be able to grab a pack that I know I can use in the most versatile of situations.

Capacity is not huge, but well supported. Handles more than a hydration pack but certainly less than a book bag.

I highly recommend this day pack.

The Osprey Manta 25 hydration pack offers easy hydration with plenty of pockets and a comfortable fit that lets you focus on your adventure, not your gear. Osprey Hydraulics(TM) 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. Included 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(TM) antimicrobial formula to help prevent bacteria and mold. 180deg 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(TM) suspension incorporates a lightweight alloy frame and cross struts with a tensioned mesh back panel for support and flexibility. Mesh and perforated, molded waffle foam at contact points along shoulder straps and hipbelt enhance breathability and comfort. Panel-loading main compartment is spacious enough for your done-in-a-day food, clothing and gear. Zippered front organizational pocket with key clip holds small items; zippered top pocket with soft lining helps keep sunglasses or other fragile items from getting scratched. Stretch-woven front pocket offers quick external storage and access; integrated patch holds a blinker light (not included). Zippered side pockets carry small items within easy reach. Zippered pocket on hipbelt keeps small essentials handy. The Osprey Manta 25 hydration pack features an integrated raincover that can be quickly deployed to keep contents dry. 3L/100 fl. oz. reservoir weighs 11 oz. Closeout.


Osprey's solution to mulit-sport day packs is the innovative Hydraulics System. This long time work in progress features an anatomically shaped reservoir that conforms to the wearer's back for a perfect, comfortable fit every time. The Manta 25 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. This is the middle sized pack in the Manta series and is great for fast hikes or runs, adventure racing or a backcountry bike ride.Features : Top zippered pocket Helmet attachment daisy Front stretch woven pocket Upper side compression straps Ventilative mesh backpanel Stow on the Go trekking pole attachment Zippered fabric hipbelt pockets Safety blinker patch Full elastic stretch sternum strap Magnetic sternum buckle for quick bite valve attachment 3-Liter reservoir included Integrated Raincover Key Clip Magnetic sternum strap buckle NoScratch(TM) Top Slash Pocket Stretch Woven Front Pocket Load Range The green to yellow zones represent the recommended load range for this pack.
