Good daypack but not what I was looking for
Well, the product itself is excellent, very esthetic and ergonomic design, very comfortable, useful pockets on the hipbelts, raincover included.... well, it's simply well constructed and has all features you might need for daily adventures, but I was looking for something that could satisfy both my biking needs along with my hiking activities. There was something missing, probably more pockets, more dividers, more storage.... For just a daypack it's perfect, but if you are a little bit more exigent and demanding like me, better look for something a bit bigger, probably 28 to 32 lts, with more outside pockets.. I would have been perfect ;)

Quick and Lite
Some days I just wake up and want to throw some things together real quick and hit the trail for a day hike.....early in early out. This pack is perfect for me. Holds everything I need. Rain gear,fleece,change of clothes, stove,food,water etc. Plenty of smaller pockets for essentials and personals you don't want to leave in the car like keys,wallet and cell phone. Side pockets can be used for nalgenes if you don't want to use the integrated pocket for a bladder inside the main compartment. Two small pockets on the waist belt are great for an energy bar or small camera. An integrated rain cover is hidden inside a zipper on the front....are you kidding me what a great idea. All packs should adopt this idea. I guess they don't get enough of your money for the pack alone. Stow and go system for my trekking poles are great. The suspension is great and keeps the pack feeling light on my back and the mesh back panel keeps my back much drier than other packs i've owned. Just a great little day pack......get it you'll love it!! I got the Tarn Blue in Large. Nice color and perfect size for me (i'm kinda large - 38in waist)

Great pack for long day hikes
I was looking for a small lightweight pack that would carry water, food, and clothing for long dayhikes. In addition, I wanted to replace a Camelbak pack that had all the weight on my shoulders. The Osprey Stratos 24 had all the features I wanted in a lightweight pack that had a comfortable hip belt: hydration slot, dual hydration ports, 3 mess small pockets in front, raincover, several easy accessible pockets, and a unique system to stow poles on the fly. This pack is designed with a frame and suspension that keeps the pack away from your back which prevents sweating. All in all this is a great pack for long day hikes as it has all the features I need and gets the weight off my shoulders.

Awesome pack!
I've used this a couple times now, and this pack just rocks. It packs and carries so well, I can barely tell it's there, even when I've got my heavy film camera and a couple lenses. And today I found out that the raincover works very well when I got caught in a gully washer about four and a half miles out.

Excellent backpack!!!
Love this backpack. Used it for the first time on a bike trip in >90 degree weather. The pack fit settled on my back comfortably and air circulation kept my back generally dry. The fit was right for my 5'2" frame and the straps were easy on the shoulders. I was not bothered by the pack swinging side to side with movement. Looking forward to using this backpack on a pack mule trip in Bolivia. I appreciate the others previous reviews on this product.
