The Osprey Atmos AG 50 is the comfort king of the 50L class. Its Anti-Gravity suspension, a seamless mesh backpanel that floats the load against your shoulders and hips, is repeatedly described by testers as the most comfortable backpack carry available, and it ventilates better than almost anything else. It is heavy by modern standards and built for comfort rather than speed, but for backpackers carrying typical 25-40 lb multi-day loads who prioritize how the pack feels, nothing else here competes.
- — Anti-Gravity suspension is widely called the most comfortable carry in the category
- — Floating mesh backpanel wraps from shoulders to hips and ventilates exceptionally well
- — Heavy for a 50L pack at around 4 lb 12 oz, far more than ultralight rivals
- — The suspended mesh holds the load slightly away from your back, reducing agility
