This here is a kind of choker, but there are also models which are worn as belts or bracelets.
Inside is very tightly compacted cloth. It can be released with the push of button and usually it assumes some form; a coat for example. Another push of the button retracts the cloth again.
This would allow you to easily manage your temperature, which for a lizard is quite useful, I’d imagine. It would also grant you protection from the dust and sand. I will try to throw something together until we reach our destination. You are free to go now. I think the captain wants to talk to you some more.
Alright! Thank you and see you later, doctor!
