backpack

Hi all, Looking for recommendations on birds backpacks. Ideally with no plastic/vinyl screens, just mesh. On amazon I am only finding backpacks that have some kind of plastic screen, which I worry about heating up and giving off gases or just overheating my bird, as I live in Miami where it is...

Has anyone used a backpack carrier to take their bird on strolls or hikes? How do you like them? How did your bird(s) like it? Does it get hot in there or is it well ventilated? Pros and cons? I'm curious! I'd like to get one but not sure what the overall opinion is of them. They seem fun!
