When we've got places to be and can't let the weather get the best of us, the Osprey Transporter Roll Top WP 30L Pack is our go-to backpack. Designed with a 30-liter capacity and a waterproof roll-top closure, the Transporter is purpose-built to handle all our essentials regardless of weather. Internal organizational pockets keep our stuff organized, and an inner laptop sleeve can accommodate up to 13-inch laptops. The Airscape backpanel provides us comfort through the use of a foam backing and a stretched mesh design, giving us comfort and breathability even if we have the pack stuffed to the max.
