Almost all of the sweatshirts that I use are Gildan brand 50/50 blend either in ultrablend weight or heavyweight. Both are nice weights in that they are heavy enough to keep you warm when worn alone but can be worn with a shirt underneath in comfort. I do use Jerzee brand 50/50 blend for the 3XL in light blue and light pink only. They are all unisex sized shirts. I have measured these myself and for the sleeve I measured from the shoulder seam to the end of the cuff. For the width, I measured across the chest under the arms. The the length I started at the bottom of the neck band to the bottom of the shirt.
