i had been using an osprey atmos65 for years, and always liked the ventilated back, and the way the frame transferred weight to the hips, as well as accessibility. as ive trimmed down my gear list, i switched to the atmos50 and used it on my hike this past spring, and it still remains my pack of choice. as much as im always looking for a better mousetrap, the pack has everything i need and not much more.
its all good
