If there was ever one nagging critique about most well-designed, ultra-ergonomic Osprey packs, it was the weight. Osprey's Atmos 50 silences the critics with over 3,200 cubic inches of pack space in a supportive and functional pack design that weighs less than three pounds. If you ever wanted a supportive and lightweight backpack for moving fast and far, the Osprey Atmos 50 is easily one of the most comfortable light packs on the planet. Anything that touches your back is covered with a breathable mesh or a special perforated waffle foam that won't heat you up like conventional backpanel fabrics. The backpanel on the Atmos 50 is stretched taut so the load sinks evenly into the lumbar support area instead of riding on your hips, resulting in uniform pressure that neutralizes hot spots. Two quick release straps on the other side of the backpanel attach to your hydration pouch for fast refill access and versatile hydration tube routing. If you're looking for a lightweight pack for fast overnight trips or minimalist backpacking adventures, the Atmos 50 backpack is one of the lightest and most comfortable designs you'll find today.
