The Air Support Light Back Panel and a ventilated harness ensure effective cooling and ultimate breathability. The bungee overflow allows you to quickly stash an extra layer without missing a beat. With a secured zippered pocket to store your keys and phone, plus an adjustable sternum strap for a custom fit and increased stability, you have everything you need to hit the trail, stay hydrated, and have fun out there.
