Built for day hikes and more technical, alpine pursuits, the Deuter Trail 24L Backpack has everything we need for a fun day on the trail or crag. The 24-liter capacity includes plenty of room for extra layers, lunch, and our water, and the suspension limits that annoying, sweaty back feeling with the Airstripes back system, which features large ventilation channels for maximum airflow. Deuter generously included a rain cover for wet weather, and the exterior of the pack features gear loops and attachment points for a helmet holder (sold separately), ice axe, trekking poles, carabiners, and climbing gear.
