Ergon’s lightweight BX1 Pack makes an excellent race-day and shorter-ride companion. No matter how you roll, with 427 cubic inches of storage and two compartments, you can easily organize all of the 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, even on bumpy terrain. And, a sleek waist-band pocket provides quick-access to tools or nutrition.
