The Eagle Creek Switchback 26 Rolling Gear Bag is two bags in one so you have a main bag for a week long vacation and a zip off, carry on backpack for day excursions on your trip. The main bag has a removable hip belt in order to reduce weight on your shoulders, and the main bag also has fully adjustable Back To Back backpack style straps that can transfer to the backpack once you're at your destination and ready to take a day trip. The main bag's ultra rugged wheels have skid and bumper protection to combat wear and tear from corners and sidewalks, and the Central Lock Point works with your lock to secure your valuables. The zip off backpack has enough pockets for you to organize your day easily whether you're exploring new cities or sitting in an airplane. Its full panel front pocket has organization sleeves for magazines, travel books, airplane tickets, or any document you may need at a moment's notice. It also has a key fob with a Porter Key bottle opener because you never know when you'll get a drink on vacation. The backpack has a sleeve for your laptop and one for your tablet, and it also features a back slip panel that makes it easy to stack this backpack on top of the main bag if you wish to roll both.
