The Cotopaxi Arenal 32 L Backpack is a technical pack for day hikes to short overnights. This pack is sized right for plenty of layers, lunch, first aid, and emergency shelter when headed out on the trail. Quick adventures still require some gear, and it's just as capable of hauling an ice axe or trekking poles if you desire. Side mesh pockets offer easy access to hydration, while the exterior top pocket and hip belt pockets make it easy to grab snacks or locate small items.
