Decent material, more of a sporty outfit than a tracksuit
I got the XXl which is what I get in Adidas when they’re cut slim. This is not cut slim. I like the looser fit, but it’s not like a tracksuit top at all, it’s like a shirt. The bottom is a plain hem. It’s way too wide for me like this. It needs a drawstring in it or an elastic waist. The material is slick and has a clean finish. The pants are the same as the top, it’s not fuzzy inside, it doesn’t have the same static cling fuzzy polyester gets. It’s thicker than I expected, more like track pants than gym shorts. I need to put some elastic thru the bottom hem so it fits better.
