From designer’s pattern description:
“Crochet this super easy, urban style chunky weight newsboy cap in just two hours-only 23 rounds! Double strand of worsted weight yarn and jumbo Q hook as a star performer makes this project fly. Chunky weight cap has that great retro look and is fun and comfortable to wear. Q hook gives stitches a more openwork look in main area of cap to allow your brain to breathe but still keep toasty. Cap has a sleek rounded shape. Please note that I specifically designed visor to be soft and have no plastic insert to allow for easy stashing away in bag, pocket, backpack,luggage, etc. Cap is crocheted in one piece and in spiral rounds (no pesky slip stitches). One skein of worsted weight yarn (200 yards) and three sizes of crochet hooks makes this a very affordable project.”

NOTE: Pattern calls for a 15.75mm Q hook.
