I have a head just barely too small for the Medium hats so I have to order the Small size and wear them one notch up. I have always wanted the Trenches style hat but they never had them in Small. As soon as I saw this one available in Small, I ordered it impulsively, and I’m glad I did! Hands down my favorite Melin hat, and I own several. The colors are great and the brick logo smack dab in the middle is perfect. Please keep the Trenches style coming in size Small.
