Gregory’s heavy-hitting trail pack is anything but weighty

Achieving fluid motion takes more than counting ounces. The ultralight Optic 48 combines weight-saving design with exceptional fit and load management to give you a low base pack weight along with mileage-crushing efficiency. Comfortable carry and thoughtful trail features keep your head in the game so you stay ahead of your thru-hiking itinerary.
