We reengineered our 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 we 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.
