The Patagonia 18L Slope Runner Exploration Pack is built with 100% recycled materials, webbing, and spacer mesh and features an exterior shell treated with a durable water repellent finish made without intentionally added PFAS to help shed light moisture. Designed for versatility and comfort across varying terrain, it offers four chest-harness pockets along with multiple expandable and static storage options on the back. A dedicated piolet-carrying system and lash point provide space for an additional item or helmet. The pack-style load management system stabilizes shifting gear, while the vest-style construction reduces chafing and enhances airflow. Adjustable dual sternum straps ensure a customizable fit, and two 500ml HydraPak flasks are included for convenient hydration. A cinch-forward closure pulls the pack volume close to the back and away from the head, with a total capacity of 18 liters.
