I really like this we used it to bring home a adopted Kitty who was very scared and she scratched and kind of went crazy inside of it but it held up fine and didn't rip and she uses it as a bed and a comfort spot we haven't used it as a backpack yet but hope in the future we will be able to. it's very easy to switch between backpack and carrier and the mesh sides and top allow Kitty to see better and have more airflow it comes with two soft pads that go inside and they are removable so you can clean them easy. It has plenty of space for them so they are not all squished I highly recommend this product you can't beat this for the priceLove it! Comfortable to carry your cat if your cat is 13 pounds or over they will probably look like they are squeezed in thereIf this has more pockets I love moreTaking cat outside with himTook my adventure kitty hiking up some bluff while she was in her backpack. She enjoyed it. The mesh extends out so she had even more room. The only thing I didn't like was it fold weird on the inside. Overall happy with itI bought this for an 8 hour flight. I was pretty nervous. It fit Alaska Airlines standards which were the smallest of all the airlines. Wish I knew that before I booked. Anyways, I left out the bag a few weeks for my kitty to check out and get used too. She started sleeping in it immediately. So when we took off, she was fine. It was very comfortable and easy for me, traveling alone with other bags! The straps were thick and comfortable. My hands free which was fabulous. Once on the plane, I put her under the seat. Then once we took off I stood the bag up and opened the extension. The extension fit perfectly under the seat and the bag poked out. I still had room for my legs. It was quite perfect. 5 stars.Pierde la forma rápidamente. La parte expandible al momento de guardarla en su lugar no tiene espacio y se mete al espacio en donde va tu mascota, reduciendo mucho el espacio aplastando a tu mascota, también la base no es resistente y comienza a perder la forma por lo que al tercer día de usarla mi perrito ya no tenía espacio para nada y estaba todo aplastado. No fue exactamente igual a la descripción ni foto ya que la mía no tenía borrega en su interior. En conclusión tiene mal diseño y le falta mas Dureza en la base y pared que sostiene la extensión al guardarla.Me gusto que fuera flexible, está Perfecto en tamaño para mi pug. Si tiene espacio para sentarse cuando no está extendida, pero prefiere el espacio extra. Es resistente, aunque no me gusta usar el “cinturón” que trae.Excelente producto a mi gatita le encantó y la usa de cama y le gusta mucho pasear y se siente cómoda! Buen espacio para un gato o perrito pequeñoMe encanto , es grande , apenas la usare , voy a salir de viaje con mi mascota parece resistente , hermosa ?La mejor transportadora! Mi gato la ama!, es muy amplia, tiene buena ventilación, el material es muy resistente. Muy practica y nada pesada.
