The Eagle Creek Ranger 26L Backpack is built to move between a full travel day and an active day without becoming a compromise on either. A GRS-certified, 100% ocean-recycled nylon construction backs the durability with a real sustainability story, while a dual-function internal sleeve carries a 13 inch laptop or a hydration reservoir depending on what the day calls for. A hidden passport pocket and trolley pass-through strap make it a natural carry-on companion, and a stowable hip belt and sternum strap keep it comfortable once it's doing double duty as a daypack. What Our Gearhead(R) Experts Are Saying:"I used this as my carry-on through security, then pulled the hip belt back out for a full day of sightseeing without swapping bags once. The hidden passport pocket is the reason I stopped patting my jacket every five minutes to check it was still there."
