I have personally tested this day pack in the Olympic Mountains - in the form of hiking, cycling, backcountry fishing, urban hiking and even as a photography bag. It performed well on all aspects. I was impressed on how comfortable the shoulder stapes are. The two external water bottle pockets also fit my function needs.
This pack can also be used everyday as a lifestyle kit. My laptop and tablet fit nice-n-cozy inside the hydration sleeve. The main compartment has enough volume and space for extra layers; much needed while living in the Pacific Northwest!
