Polyester and cotton?

Who likes to wear polyester tracksuit jackets and cotton sweatpants?

I've always worn the same sets, either made entirely of polyester or entirely of cotton. Which is also great, but lately I've been loving wearing my Adidas polyester tracksuit jacket and my Nike fleece sweatpants. I just love this outfit; I mostly wear it at home to chill, but it's soooo soft and, thanks to the tracksuit jacket, it's not always too warm and can be put on and taken off quickly.

Who likes to wear the same combination?
