Folks have been asking us for this wardrobe basic for years. Ones with polyester thread are all over, but for garment dyers, there is a lot of double stitching that would look bad. So we finally found a new vendor right here in the U.S. that would custom make them for us at a price that wasn't off the charts. They are made from a great super soft 100% 9 oz. cotton fleece and sewn with cotton thread! Cut a bit over sized so they shrink to fit, also cut a bit longer so they are right in style. Garment dye 'em, tie-dye 'em, embroider, stamp, screen print, do transfers, we could go on and on. Keep those kids warm and colorful at the same time.
