The Osprey Exos 38 is so light that youll want to tether it when its not strapped to your back. Everything about this pack is featherweight, starting with the mesh Airspeed Suspension which stabilizes the load and simultaneously provides maximum airflow for high-output ventilation. An ExoForm hipbelt and shoulder harness combine for all-day carrying comfort.

Osprey designers built this pack from light but durable 100D High Tenacity nylon and added superlight YKK zippers. Along with ultra-light materials, the top lid is removable, as are all external straps to shave a few more ounces. The integrated Flapjacket remains to protect your gear if the weather turns nasty.

Mesh side pockets with InsideOut compression combine storage and stability. The front stretch mesh pocket gives you quick access to a map or an extra layer. Two zippered hipbelt pockets keep snacks and essentials secure.

The pack includes an ice axe attachment loop in case youre in the mood to blitzkrieg an alpine adventure. External cord tie-off points give you the option to lash on additional gear.

If you want to fly through the backcountry on winged feet, this is the pack for you.
