The VO24 is just as great on day hikes as it is in 24 hour adventure races thanks to durable Velocity fabric in the main body and spacer mesh in the back and shoulder straps. The adjustable sternum strap has a built-in whistle. There’s plenty of room for storage in the large front pocket two side angled pockets and bellowed pockets on the hip belt. Though it only weighs 1 lb 9 oz the VO24 is definitely a heavyweight when it comes to hauling! Imported.
