We purchased a Roverlund backpack for our 3.5lb chihuahua, Tito, who often travels on flights with us. The backpack design offered PLENTY of room for her to move around and look out, whether in the vertical position looking out the mesh 'windows' or lying horizontally on the floorboard of the plane for a quick nap.
There are compartments to carry her collapsible water bowl, a peewee pad, some chew bones, a small bag of food, and wet wipes. The pack also comes with a clip-on holder for **** bags! It's like a Swiss-Army knife for pet travel.
We were blown away when Roverlund replaced our 1st backpack, no questions asked, due to a faulty manufacturing glitch. The 2nd pack is perfect and we've broken it in by traveling the East Coast! Tito approves, and Tito's parents give it 5 stars! We love our Roverlund, hands-free backpack travel bag. It's a game changer for pet traveling. I throw the pooch on my back, a purse on my shoulder, and roll a carry-on for the human stuff. It doesn't get much easier. Thank you Roverlund!
