storage pocket is too small to fit my I-phone max in!
The storage space is very limited, more so than I thought. But I wanted something more streamline to complement the kitari 7 that I use a lot, and love, so this is it. It barely fits my I phone max, but it fits so I upgraded from an earlier 4 star review.

Great pack for light day trip
Didn't use water blader, 16oz water bottle fits in side pockets and main compartment is perfect for day trip.

None better!
No matter the activity, this thing is a life saver. Workmanship and quality are top-notch and the pockets are very handy for items I don't want to carry or put in my pants pockets. I use this when working outside, riding the trails on my adventure bike, paddle boarding, hiking, you name it. The harness is very comfortable and when I have it adjusted properly, I forget it's on my back...until I get thirsty, of course. The bladder and tubing are sturdy, not cheaply made. No leaks and no issues...just reliable hydration and yes I would buy it again.

Love it!
I love the color! I got the green one and I’m super happy with it. I was impressed with the quality of the stitching and the straps. My favorite feature was the water bladder. It’s easy to drain and fill as needed. I had an older one that I could never get to dry, but this one you can leave it all the way open and it will drip dry. Super happy with it and I would definitely recommend if you are looking for a nice one of these!

A Nice Hiking Companion
I've been a big fan of Osprey hydration packs for years and my normal one is a bit larger. I got this for the kids or for short hikes where you didn't neat to bring much other than water but wanted to have your hands free and this fits the bill. Made with the normal Osprey features, this will be a nice addition to the outdoor kit.
