The most common question we get on custom hat orders isn't about logos. It's about fit. Here's what the three closure types actually mean, and how to choose when you're ordering for more heads than just your own.
Snapback: one size fits most
A snapback has an adjustable plastic closure at the back. It typically covers roughly 6 7/8 to 7 5/8, which is the vast majority of adult heads. The Richardson 112 is the classic example. When to choose it: any group order where you don't know sizes, like work crews, events, customer gifts, or resale merch. Nobody ends up with a hat that doesn't fit, and you only manage one SKU per color.
Flex-fit: stretch comfort in size ranges
Flex-fit hats, like Richardson's R-Flex on the 110 trucker, use an elastic stretch band instead of a snap. They come in ranges, usually S/M and L/XL, and they feel snugger and more premium than a snapback, with a clean back and no plastic. When to choose it: daily-wear staff hats, or merch for buyers who'd pick a fitted cap at retail. For group orders, a simple rule of thumb works: stock mostly L/XL for men's crews, and an even split for mixed groups.
Fitted: exact sizes, exact heads
True fitted caps come in precise hat sizes (7, 7 1/8, 7 1/4, and so on) with no adjustment at all. They look the cleanest, but they're the riskiest for a group buy. You need everyone's actual size, and exchanges eat up time. When to choose it: teams and uniforms where you can collect sizes up front, or personal orders.
Our take for most orders
If you're not sure, the adjustable snapback wins on practicality. That's a big part of why the Richardson 112 is the most popular custom hat in America. Still deciding on a style? Our hat styles guide compares trucker, dad, snapback and 5-panel, and the Richardson 112 vs 110 vs 115 breakdown digs into those three models. Browse custom Richardson hats or all custom embroidered hats, and remember: no minimums, and you approve a real stitched sample of your logo before we produce anything.
