Nice, Soft and Comfortable Tracksuit
First thing my son said when he put it on and the quarter zip was down was that he felt like Paulie Walnuts off The Sopranos. It cracked me the heck up. With the collar that kind of butterflies out, but still stylish.
This is a nice and quality tracksuit. It is made of soft polyester and the spandex makes it stretchy. It fits true to size. It fits loosely so you have some room to move around. I got this for my son as he had no athletic type clothes to wear when it gets cold. It is kind of a good thing that the material is not heavy, but it generates heat and is perfect for colder weather. you can't wear it when it is in the mid-70's or so unless you are just a cold natured person. Wearing a T-Shirt under it is great.
The tracksuit is perfect to wear to sporting events, a sports bar or shopping on a spring or fall day. The pants fit well and are the proper length. My son is 6' and a buck sixty-five. Fits him like a glove and it still would if he were heavier. The elastic waist is nice and the cords are not uncomfortable like some can be.
I recommend this product.

Amazing look and value for the price
Color: Navy Blue, Size: Large
This is an amazing piece of clothing and despite being so cheap (under $20), it looks super clean and professional. I love the way it fits and feels. It is polyester but it honestly is so comfortable that it feels like wool. I was a little nervous about buying from this brand at this price but I am honestly hooked onto Coofandy now. I usually wear a L but I got a M for a more flattering fit and since I have a shorter torso.

Husband approved pullover sweater
Color: Navy Blue, Size: X-Large
Nice warm men’s stylish sweater. Fit my husband well. Pull over is cozy casual. He says it’s a good weight for warmth and moth itchy… and that’s something to say as he doesn’t usually like sweaters!
