It's not just the weight of your pack—it's how you carry it. The Spire™ keeps the weight (and the sweat) off your back thanks to a lumbar reservoir and suspended mesh back panels. The reservoir stores your hydration near your hips for greater stability on the trail, and the mesh NV panels keep your back cool and ventilated no matter how rugged the climb. The Spire is also engineered to fit women ergonomically, with an S-curved harness that keeps the pack closer to your body, and a sternum strap that sits comfortably across your chest. That way, you can forget about your load and focus on the trail ahead.
