To optimize weight and comfort for our longest hikes Osprey has modified the Exos and created the Exos Pro 55L backpack. This ultra-lightweight design sheds almost a pound over the original and a few more ounces when the cover is removed. Supporting parts from the inside allow us to manage the weekly load and adjust the power if necessary balance and organization.

The Osprey's comfortable carrying system starts with the Air suspension
Speed. This stretch mesh back panel provides support and provides plenty of space between your back and pack for cool airflow on the longest hikes. Silicone print on the lumbar area helps the hip belt stay more stable so the dynamic foam waistband can stretch and move with your hips without sliding down your back. Mesh shoulder straps are also ventilated , providing air circulation around the body.
