Durable and water resistant, the Orvis Trekkage LT Adventure 27L Backpack is our best friend when we need a carry-on or premium day trip bag. The Trekkage LT makes travel comfortable with its padded ergonomic back panel and padded shoulder straps that also allow for plenty of airflow. It's highly durable with its 600-denier Cordura face fabric and also water-resistant with its TPU coating. The interior features plenty of room, including a hidden security pocket and padded laptop sleeve, while the exterior features expandable mesh side pockets that conveniently let us carry a water bottle or secure a fly rod tube to our pack. From the terminal to the trail, this pack has our back.
