Most comfortable hiking backpack ever!

This backpack is perfect for carrying the essentials for a day hike. It is super comfortable and it is ideal to have certain items accessible in the front pockets. The front zipper pocket is large enough for the largest size iPhone. The side belt pockets are also very large and have easy access. I highly recommend it for people with shoulder issues. I think it also improves posture because it helps you maintain the back straight and the shoulders over the hips and not hunched at all. What a great feeling to have a backpack that hugs your body and moves with you and not against you. Best hiking backpack I ever had. I am so happy that Osprey is making the Tempest with the vest style straps. That one is definitely my next purchase for winter hikes when I have to carry much more and need a larger one. One negative: It may be hot in the summer. Still, the comfort out weights the heat, for me.
