This is a pretty new pack from Osprey, geared towards running, but find it equally nice for mountain biking. It's a small pack- 1.5 liters according to Osprey, but it seems to pack a little more than the volume would belie-more on that later.
Weight is a svelte 11 oz (16 oz w/ the bladder). The most important aspect of a running (or biking) pack is that it rides comfortably and doesn't bounce- they really hit the mark w/ this pack- it is bar none the most comfortable pack I've run w/ (and I've run w/ a lot of packs!).
The bladder is 1.5 liters and that is as big as a bladder as it will hold. It's a nice setup in that the tube can be easily separated from the bladder, which allows for a very quick removal (& reinstall) of the bladder.
the bladder is neat in that it has several baffles that cut down on sloshing
this isn't new for Osprey, but a feature I love- it's a magnetic piece on the bite valve- which secures the valve to the sternum strap- very handy!
the pack has a nice adjustable bungee setup- easily fits my rain jacket and windshirt
the harness setup is very comfy and w/ two adjustable (adjust up and down as well as length) sternum straps- very secure
it has two stretch pockets on the right side- I carry food in those-fits a couple of bars in the rear pocket, the front I carry a couple packs of shot bloks, the right pocket has a large stretch pocket that my camera goes in- in addition it has a "digi-flip" feature- the pocket flips out and is meant to hold a smart phone- I use it to carry my maps
there is room in the main compartment where the bladder is for additional items- I keep a beanie, gloves, buff, extra food, emergency blanket in it
also a small slash pocket, that I keep additional food, sunscreen, bug dope and my waterproof ditty that includes a small knife, fire starting kit, headlamp, whistle, TP and small first aid kit
full loadout
I've run several 20-ish mile trips w/ this pack and it's definitely my new go to pack. It's nice to have a light pack that holds everything you need, that's comfortable enough you forget it's on
