Fabric on fabric noise when driving

[wcgary]

Just leased a 2016 4D TRD 4x4, and when I driving over uneven pavement, there is a strange 'polyester pants' sound inside the cab.
I've had the truck a whopping 4 days, so I'm hoping that this sound will settle down as the truck gets some drive time. I haven't been able to ID where the sound is, but it's rather annoying.
Anyone hearing anything similar?

Have you rolled down the windows to check if it's inside or outside?

It's inside; and it's faint enough that it can't be heard over the stereo, but it's flat out annoying me.
I've checked the seats to make sure they're secured, glove box, sun roof, etc.

Annoying

Did you check the rear seatbelts to see if they are secured in their clips? Storage compartments under and behind seats to see if anything is sliding? Sorry, but those are my only ideas.

Thanks TacoRick. I'll try continue my search and let you know what I find.

Did you try tucking your shirt in ?

I guess the uneven pavement is causing you to shimmy in your polyester pants? That's weird.
