My son, an LDS missionary in Brazil, has a couple of shirts from several different companies that he's used over the last 18 months. He lined them all up and sent me a photo in a row, and by far the &collar shirts were the most white, hadn't popped any seams, were his favorite as far as comfort (in muggy intense heat) and were entirely wrinkle-free whether he washes them in a bucket by hand or in a washing machine. He gets through the rainy Amazon season, and they dry after flash storms, as he's walking, and the collars have stayed stain and fray-free. Incredible and so appreciated! He asked me to send him more to replace all the other brands for the rest of his time there. Thank you!
