The Spire 22 LR keeps the weight 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 suspended mesh back panel keeps 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.
