not a big fan
dont really like the set, the neck on the shirt is much smaller than it should be, tight around the neck, the pants are nice, comfortable and feel like they will last

Absolute horrible quality
Color: Black, Size: Medium
Do not purchase this track suit even if its on sale. The fabric material is so cheap, it feels like a tacky uncomfortable plastic bottle that's been stretched out over your body. The stitching feels very off and the thickness is somehow too bulky and looks baggy and at the same time feels too tight. Do yourself a favor and avoid, I'm returning this product.

Nice lite weight shirt
Color: Black, Size: Large
I love love love Coofandy men’s clothing line. It is affordable, good enough quality for my purposes, and nice looking.
This lightweight quarter zip is no exception.
I like the material, the fit, and the price!
I basically have bought an entire new wardrobe from Coofandy!

Great purchase!
Color: Brown, Size: Large
I love this quarter-zip. It's soft & fits great. The color choices are great as well. It's a great change of season top.
