SturdiBag™ XL Pet Carrier is an ultralight pet carrier made of tough nylon fabric with tension rods that give it shape and is collapsible for storage. The solid floor and included pad ensure your pet's comfort and is designed for pets up to 45 lbs. This is the perfect travel carrier for your dog and cat, but be sure to check the dimensions with the company. For this reason, I trimmed the length of the board from 20" to 19.5" in order to fit the underseat dimensions that the airline required, but this doesn't affect any function or aesthetics -- see the photo. For your convenience, it is machine washable -- just remove the buttons and wires first. It measures 15" tall x 12" wide x 20" long. Thanks for your interest in my listing!
