Osprey Kamber 22 hiking/skiing backpack, with a 22-liter capacity.
It appears to be an older model, and the second photo shows features including:
* Hydration-compatible compartment (H₂O marking)
* Helmet carry/storage
* Waist/hip belt
* Multiple gear attachment points
* Osprey’s suspension/back-panel system
It’s designed primarily as a ski/snowboard day pack, but it also works well as a hiking/daypack.
