It’s super comfy for the dog and generally for the person wearing the back pack. One flaw that easily can be fixed is that The hard plastic on the bottom makes it sore on the lower back if carried for two days in a row. So there should be padding on the plastic as well.

I needed to transport my dog on the plane and this backpack is perfect! When we go out, she actually likes to stay in the backpack as a safe place.

The bag is excellent quality and well designed. I secured the Secured bag onto my bike and my dog now loves joining us on bike rides. I like the fact he’s on his feet rather than placing stress on his spine. Because the bag is attached to the bike, he feels very safe and secure.

I love this backpack and use it all the time, I've had it for 3 months now and its gone with me on a couple of flights as well as many bike rides and hikes and even a 10k. I chose the red one for extra visibility. I also like that I have a spot for my laptops, and his water bottle. I ride with him tethered in with the strap on a safe no-escape harness. I would however pay twice as much for the exact same backpack if i could get it with sturdier materials. Instead of a plastic bottom with fiberglass rods something stiffer that could handle if I fell off my bike and kept him from being potentially crushed, like a safety roll cage, but I haven't found anything yet that offers that level of stability.
