There is a great website dedicated to American made apparel. It is called Always Made in USA. They carry clothing for Men, Women, and Children. I have 1 pair of jeans from them and two hoodies I wear at work. I assure you that they are very durable, and the jeans fit great and are very comfortable.
But here's the best part, The clothing line is donating 10% of all profits to http://www.cfsrf.org/ which is the Children of Fallen Soldiers Relief Fund. Check out all that they have to offer HERE
