Previous orders were my regular size but after washing they would shrink and to tight for comfort. After ordering up a couple times and washing. 7 5/8 regular size to 8 1/4 (5/8” larger) found my fit after a wash and dry. After that challenge to find my comfort size they are perfect. They will shrink so save some cash so you don’t have a stash that won’t fit or be uncomfortable after a wash and up size definitely. Great cap solid construction, stitching, and comfortable under that hard hat.
