When you're running over hill and dale your gear needs to be simple and functional. Good gear helps you go the distance without hindering the cause. It wicks sweat so you don't overheat, and blocks the wind so you don't loose body heat. It balances minimal weight with maximum performance.
Our Trail Running packs weigh next to nothing. All the trimmings are there for a hydration system - either bottles or a bladder with a port for a tube.
