Excellent
Color: Navy Blue, Size: Large
Excellent product. Attractive weave design. Fabric is comfortable and thick enough to hold its form without being too warm. Holds up well to machine washing. I ordered a second set in another color and also an other shirt in a contrasting color and design. Perfect fit.

It fits true to size.
This fits my husband perfect. It is not too sporty but sporty enough. If we were going somewhere dressed casual this suit is it and he would still be comfortable. He is a sporty guy always. It is nice to see him a little more dressed, but still comfortable. This is great material.

Definitely stylish and true to fit
An amazing set fits perfectly. I would necessarily call it a track suit because it’s more stylish than that however, the comfort is track suit / walking suit feeling. I got mine in 2x and it fits as I expected it to so yes it is true to size. The colors don’t fade and the weight of the set feels like it was made with quality material, not some flimsy sown together item full of loose strings.
