Specifically designed with travel in mind, the Aer X-Pac Durable Travel Bag Collection can handle quite a bit. With these durable bags, there’s no need to carry a separate waterproof cover that takes up space inside the bag. Because they’re made using sailcloth technology, these bags are waterproof and strong enough for both indoor and outdoor use. This series of waterproof bags includes Hip Belt, Day Sling 2, Fit Pack2, Flight Pack2, Duffel Pack 2, and Travel Pack 2. Aside from the belt bag and sling bag, all are travel backpacks. Ranging in capacities from 4.5 liters to 33 liters, these bags can carry a wide array of your belongings. Plus, the backpacks have hidden spots for your passport, tablet, laptop, and other valuables. With the Flight Pack, you even get a lockable spot to protect your more precious items.
