Ergon’s mid-sized BX2 pack makes an excellent companion for riders who like to travel relatively lightweight. The 610 cubic inch cargo area is expandable to 702 cubic inches, and you have two compartments for organizing all of your ride essentials. Its rugged rip-stop nylon construction stands up to the rigors of long days on the trail, and the airy, 4-zone open-mesh SpacerFabric provides cooling airflow along your back when the action heats up. You’ll love Ergon’s Adaptive Carrying System, which hugs the pack snugly against your lower back and hips for a secure fit, and an adjustable back panel gives you a custom fit for maximum comfort. Plus, a sleek waist-band pocket provides quick-access to tools or nutrition.
