Review on 🐾 Lightweight and Ergonomic Pet Carrier Backpack - Heavy Duty Dog Carrier with Comfortable Straps - Versatile Small Animal Carrying Backpack with Breathable Mesh Openings - Easy to Maintain Dog Carry Bag for Pet Owners by Amy Cummings

If you want to hike or bike with a small pet, this is not the solution. The bottom of the bag sags when you carry it on your back. Please note the description does not say anyone is wearing it, this would be false advertising. Calling it "Heavy Duty" is a lie and grounds for a free return. The material is good with double stitching and a soft lining but has little to no support and the zips are the same as anything else we've tried. Longevity is questionable (this is our third attempt at the bag at Revain and first without a broken zipper on arrival). Our dog is 12 pounds and looks terribly uncomfortable when I try to carry him as a backpack. Unlike other bags we've tried, this one can be used as an airplane holdall, the back is padded and has some [maybe] water-resistant nylon. It's also roomier than comparable models. If you only need to carry your pet on your back at the airport and on the plane, or for short trips, this pet carrier might be for you. I strongly advise you not to buy this if you intend to travel actively with your pet.
