Cotopaxi reengineered the 5-star Allpa 50L Duffel to use recycled fabric and carry even more comfortably. The backpack shoulder straps are now easier to remove or reattach, and they added a stuff sack for easy duffel storage between trips that can double as a bag for shoes or laundry. Meanwhile, the durable yet lightweight fabrics—now made from recycled materials—are as burly as ever.
