Nice material, quality, comfortable

Nice quality, soft. He likes it! It does run a bit big in the shoulder, but overall he likes the fit. Would purchase this one again.

Super Comfortable Crewneck
Size: Medium, Color: Grey Heather
This has become the sweatshirt that somehow disappears from the closet first. The fleece is soft without feeling overly heavy, and the fabric has a bit of breathability so it stays comfortable for everyday wear. It works well as a simple layer for cooler days or lounging. The fit is relaxed and the crewneck style is easy to throw on over a T shirt. One of those straightforward sweatshirts that quietly ends up getting worn a lot.

Cozy and soft
Size: 4X-Large, Color: Red
This brand of sweatshirt is true to color and size. I find it is cozy and well made. It has some stretch and give but only enough to be comfortable, not so much that it looks weird.

Nice & comfortable
Size: XX-Large, Color: Grey Heather, Size: XX-Large, Color: Grey Heather
This is a nice & comfortable sweat shirt. I wear a 2X and this fits me comfortably. The stitching is right on as there are no loose threads anywhere on the shirt. This shirt is medium thickness & has a little bit of stretch to it, which is all one needs. From underwear to sweatshirts FOTL has does a great job once again. For the price paid you are getting a great value for your money.

Nice fit and warm, but bad material.
Size: 4X-Large, Color: Black
Not good material, now it looks like having four or five years of use and is not 1 year old.
