You’ll find Osprey’s women’s specific Mira AG™ 26 is ideal for a day hike. The Anti-Gravity (AG™) suspension system—combination of LightWire™ frame, mesh backpanel, BioStretch™ shoulder harness and AG™ hipbelt—distributes weight to keep you comfortable no matter how far you roam.

The pack’s main compartment is accessed via a front zip panel so you can see all your gear at a glance. A series of well-designed pockets keep you organized on the trail. There’s a large zippered front panel pocket with internal mesh pockets for securing small items. Dual side stretch mesh pockets provide space for extra water bottles and the hip belt has two zippered pockets for keeping trail snacks or a phone. A scratch-free zippered slash pocket provides safe harbor for your shades.

Additional storage features include a helmet attachment loop and Osprey’s Stow-on-the-Go™ trekking pole attachment system to stash your sticks. An integrated removable raincover protects your gear if the weather rolls in.

This pack comes with a Hydraulics™ LT 2.5 liter reservoir complete with Osprey’s magnetic sternum strap bite valve for instant access to fluids.

I love this pack


It sounds like at least one reviewer had the wrong size. I have never worn a more comfortable pack! I am small framed and packs are usually very uncomfortable because they are too big. I hiked the Rim Trail In the Grand Canyon, about 25 miles, and this pack was amazing. I love it so much.

I received this for my birthday right before we went on a hiking vacation so I did not have time to try it before bringing it on the trip. I hate this pack and do not want to ever use it again as I was forced to do on the trip as it was my only means of hydration. I tried one more time when I returned and again it was unbearably uncomfortable. I was told the pack was not returnable by the giver. The hydration system is fine but the pack rides up to my waist and then the breast straps choke me. The waist band is so snug that I have to pry the back off. The side pockets are difficult to access and the zippers are not easy to use. I have never met a pack this uncomfortable in my decades of hiking.

A very frustrating pack


I purchased this specifically for a trip to Utah. I like all the compartments but as a normal woman with hips this back pack rode up and over my hips non stop. I felt like it would only work if I put 5 big rocks in it to keep it where it belongs. It also toppled over my head with any bending over. After a 10 day trip in Utah where I used this as a day pack for water, camera gear and light clothing I gave up on it. I decided to give it another try skinning up a small mountain here in NH. Same thing, it rode up my body non stop and was very frustrating. I would not recommend this pack.

Raincover issues


The integrated rain cover does not work as such. On rain water leack throught as well as into the backpack. At the end of a 4 hr walk there is water inside the pack. Do you have any suggestion? I used to have a JackWolfskin, and these raincovers are better.
