Brand: OUTDOOR PRODUCTS Dimensions: 33L x 23.5W x 44H cm Material: Polyester Features: Lightweight Recommended Maximum Weight: 6 kilograms [For outings with your pet!] The front has a double flap, so it can be used as a regular backpack when both flaps are closed, or you can open only the outer flap to reveal a mesh flap, allowing you to see your pet. It's a great help in various situations, such as when using public transportation, entering pet-friendly facilities, or going to the vet! [Excellent breathability for your pet's comfort!] Even with all the flaps closed, the sides are mesh, providing excellent breathability! It gives your pet fresh air and doesn't make them feel cramped. The mesh window is made of high-quality materials and is resistant to scratches. It's too small for my pet (4.5 kg), so I haven't used it. There are some fold marks due to long-term storage. Please refrain from purchasing if you are looking for something in like-new condition. Please check my profile before purchasing. Thank you.
