    Comfortable and Slick
    Color: Grey, Size: X-Large
    The track suit has been my tai chi workout go to. The fabric is light and non constrictive so I can move effortlessly. The material is soft and feels nice. Does not get too wrinkly when folded. The color is nice. Top fits nicely, true to size (6’ and 190 lbs). The bottoms are a bit baggy though but my bum is flat, so can complain. I think next time I would purchase separate pieces and go with XL top and L bottom. Perhaps mix the colors too so I don’t look like an orderly on break! I will caution on wearing this type of material over spandex or slippery underwear. I was walking my three large dogs and they got tangled and the leash snagged and pulled down my pants exposing my underwear to the world. Luckily, I had clean undies with no rips, although no one was around the trail we were on! This is my first Coofandy purchase and I would definitely purchase again.
