Made for a full day of riding cross-country singletrack, the low-profile B-Line XC offers a comfortable carry mile after mile. Tailored specifically for women, it comfortably carries 3 liters of water with the new fast-flowing, taste-free Big Zip EVO reservoir while leaving sufficient room for packing. The RidgeAir back panel ensures plenty of airflow for cool-riding comfort. Available in 8.0L & 12.0L sizes.
  • Women's Fit: Designed and built for optimal fit and comfort, the B-Line features soft-touch materials at body contact points, an optimally sized back panel, anatomically shaped and angled waist belt and shoulder straps, as well as a long-track sternum strap adjustment.
  • RidgeAir back panel: Ridged foam with ventilation channels and lightweight, breathable mesh ensure cooling airflow and carrying comfort.
  • 3.0L Big Zip EVO reservoir: Premium taste-free and BPA-free water reservoir features a 50% faster flow rate, low-profile shape, wide-mouth opening that seals securely, and a convenient quick-disconnect hose.
  • Smart hydration pocket: Hook and loop closures hold the reservoir securely in place while you ride; dedicated hydration pocket makes it easy to access reservoir for refilling or cleaning.
  • Easy hose routing: The drink tube can easily be routed on the right or left by threading the hose through the webbing loops on either shoulder strap (note: routing over the right shoulder is recommended, as it allows the bite valve to easily return and reattach to the magnetic clip).
  • Internal Organization: Zip mesh pocket with key retainer, three mesh stash pockets, and two pump sleeves keep bike tools, food, and keys within easy reach.
  • Helmet carry: Front stash pocket expands to securely carry a helmet(available on 8L, 12L).
  • Ultracompact: 2 webbing straps attach a helmet for secure carrying (available on 5L).
  • Reflective detailing: Reflective hits enhance your visibility to others when you're on the trail or traveling between rides.
