New for 2012! Resurrecting the award winning Mountainlight category, Mountainsmith's brought the Phantom 40L back to life! Sporting considerable updates over the previous classic, this weekender 40L panel loader is built with durable, lightweight high tenacity nylon and loads of ergonomic features ensuring years of fast, light, and comfortable trail use. Available in two torso sizes, Mountainsmith's Breezeway trampoline suspension backpanel sports a coated mesh sling for increased airflow, DWR coated airmesh foam for increased breathability, and innovative ICS Cup (Illiac Crest Shelf) hipbelt that transfers and locks the pack load onto the hips for increased stability. To round out the comfort and optimal load transfer, Mountainsmith included a Lumbar Control Point pad on the lower backpanel to fully secure the pack load against the user's major weight bearing point, the lumbar/sacrum region.
