We reengineered our 5-star Allpa 70L Duffel to use recycled fabric and carry even more comfortably. We made the backpack shoulder straps easier to remove or reattach, and added a stuff sack for storing the duffel 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.
