The Osprey Mira 22 is a well-constructed, feature-rich hiking daypack that comes with a hydration system that holds 2.5 liters of liquid. The size works well for shorter hikes and/or hikes in warmer weather conditions that don’t require a lot of gear. It has a ventilated tensioned mesh back panel to help keep you cooler with a fully integrated women’s specific hip belt and shoulder harness. It can be adjusted to different torso lengths so that you can really dial in the fit. I’ve tried Osprey packs many times over the years and the Mira 22 is the first one that I’ve found truly comfortable. It’s available in neutral colors and makes a great day pack.

Backpack Storage and Organization
The Mira 22 is a panel-loading backpack a U-shaped front zipper to access the main compartment making access to the interior easy. There is also a side zipper that accesses an additional pocket for access to other small items with an interior mesh pocket and key clip for organization. The main compartment has a separate hydration section that is accessed via a separate zipper at the top. It would easily hold more than just the reservoir. There is a port at the top of the pack for the hose and another zippered pocket on top for securely storing some small items like sunglasses etc.
The Mira 22 has a front stretch pocket which is good for holding loose layers and snacks and two side stretch pockets, that can hold a sit pad or water bottles if you prefer to carry them instead. There are two tiers of side compression straps that can be used to lash bulky gear to the side of the pack and hip belt pockets are provided that are large enough to hold snacks, a small cell phone (up to 3” x 6”) or a small camera.
The water bottle pockets are made of a sturdy, stretchy fabric and sized for thinner bottle than a Nalgene, although a 1L Nalgene will fit if you are insistent. You can put bottles into the pockets from the top or through a side opening which allows you to take them out and put them back while wearing the pack. You’ll still want to use a fairly short bottle because longer ones fall out the side if you bend over.
Like all Osprey Packs, the Mira has a stow-and-go trekking pole attachment on the side of the pack which is useful when you want to keep your hands free, especially for scrambling. An ice tool loop and bungee are also provided for alpine or cold weather use. There is also an integrated rain cover stowed in a bottom zippered pocket.
Backpack Frame and Suspension
The Mira 22 is a ventilated backpack, with a panel of mesh covering an air cavity behind your back. This helps keep you cooler and cuts down on perspiration on hot and humid days. The Mira also has an adjustable torso length, so you can really dial in a personalized fit. What I find impressive is that Osprey put this suspension on a 22 liter daypack since it was first developed for their higher capacity overnight and multi-day backpacks.
The back panel is tensioned to allow ventilation and while the integrated hip belt provides excellent hip wrap and load transfer. The adjustable yoke design tracks on the AirSpeed frame and buttons into a webbing ladder. It’s an ingenious system that cuts down on bulk and weight you might find with more typical hook and loop systems. The belt webbing is a generous length and the hip belt is well padded.
The women’s specific perforated shoulder harness is covered with perforated mesh and the foam structure is also perforated to improve breathability. I find it very comfortable, even in sweltering hot and humid weather.
Included Hydration system
The Mira 22 comes with a 2.5 liter hydration system so you don’t have to buy a separate one. However, if you already own a hydration system you prefer to use it will also be compatible with the pack. The Mira hydration system includes a magnetic bite valve/hose holder attached to a shoulder strap so the hose does flop all over the place while you hike.
The sternum strap has a magnetic bite valve/hose holder on the buckle, although the hose tends to flop around uncontrollably when you take off the pack. You can remedy the hose attachment problem by running the hose through the small elasticized bands on the shoulder harness in order to secure it.
The reservoir opens with a foldover flap and sliding clip at the top. There is a quick connect partway up the hose which allows you to fill the reservoir with a compatible system without taking it out of the pack. The hose is a bit long for this pack, but shortening it is easy. The bite valve has a twist on/off switch to reduce leaking. I found that it was pretty leak-proof without turning it on and off every time I used it.
The Mira 22 does not come with a bite valve cover however, but they are available for purchase separately. Personally, I like a cover to keep dirt off the part that goes in my mouth. One disappointment with the bladder for me is that the quick connect is partway along the hose. While I like the functionality of the bite valve, this valve is so secure that I have not found a way to dry the hose without taking the bite valve off.
