Before you buy on a number alone, use our hat sizing guide, read your head shape and hats and your face shape, or book a free hat fitting so we can walk you through it in person.
Walk into any serious hat shop and you'll hear it sooner or later: “That's a 10X.” Or a 4X. Or a 100X. The number sounds precise — like horsepower or thread count — but what does the X-rating on a felt hat actually mean?
In short: it's felt quality. Higher X usually means finer fur and a higher price. What it does not mean — and this is very important — is a single universal standard that every brand measures the same way. If you are not buying your hat from a long-established brand (ahem, Stetson and Resistol), then there really is no universal measure — it's just what that hat company decides it will be. Beware lesser-known hat companies with high numbers of Xs. That doesn't mean they can't be good, but validate their reputation, because some do lie.
Here's how to read the number without getting lost in marketing.
What “X” actually refers to
Felt cowboy hats and dress hats are made by interlocking animal fibers under heat, moisture, and pressure. The blend of those fibers — and how finely they're processed — is what the X-rating is trying to communicate.
Lower X hats typically have more wool or are heavier on rabbit. Higher X hats use a greater share of finer fur, especially beaver. More beaver and a finer finish generally produce felt that feels smoother, holds a shape more cleanly, shrugs off weather better, and lasts longer with proper care.
Think about where a beaver lives — it's definitely going to handle the elements a little better than, say, a rabbit or sheep.
Think of X as a quality ladder for fur felt, not a grade for every hat on the wall. Straw hats, wool felt, and many fashion felts aren't X-rated in the same way — and they don't need to be to be excellent hats.
How the scale usually works
You'll commonly see ratings like 3X, 4X, 5X, 10X, 20X, 50X, and 100X (and higher on some premium lines). As a practical rule of thumb:
Entry and everyday fur felt (roughly 3X–5X): Solid starter and daily-wear territory. Durable, shapable, and a smart place to begin if you're buying your first real felt hat. At Moon Ridge, we love the Resistol Tucker, Stetson Oak Ridge, Stetson Red Rocks, or the Stetson Corral at this price point.
Mid-range (around 10X): The sweet spot for a lot of serious hat wearers. Noticeably finer hand, better water resistance, and a finish that holds a custom shape beautifully.
Premium and heirloom (20X and up): Finer felt, lighter feel for the quality, and the kind of hat people keep for decades. You're paying for fiber quality and craftsmanship — not just a bigger number on the sweatband.
Those ranges are directional, not gospel. A well-made mid-range hat from a brand you trust will outwear a poorly cared-for “high X” every time.
The catch: brands don't share one ruler
This is the part most product pages skip. Stetson, Resistol, and other makers each use their own X scales. A 10X from one brand is not a laboratory twin of a 10X from another.
So use X-rating as a starting signal — finer felt vs. more basic felt — then judge the hat in hand: weight, softness, how the crown and brim respond to shaping, how the finish looks in real light, and how it sits on your head.
At Moon Ridge, we would rather have you try two hats side by side than buy a number. The right hat is the one that fits your life, your climate, and your head — not the one with the biggest digit. Let us talk you through this part of the process — book a hat appointment, come into the store in Fayetteville, or start with our sizing guide before you order online.
What higher X usually gets you
When the felt is genuinely finer, you tend to notice:
A smoother, denser hand. The surface feels more refined. Creases and brim work look cleaner after shaping.
Better weather manners. Quality fur felt generally handles moisture and humidity with more grace — still not a raincoat, but more resilient than a basic felt.
Longevity. With brushing, proper storage, and professional cleaning when needed, a higher-quality felt is built for years of wear, not one season of photos.
Shaping potential. Finer felt often takes a custom crown and brim set more precisely — which matters a lot when we're dialing fit to your head shape and face.
What X-rating does not tell you
X-rating is not a fit guarantee. A 100X that gaps at the temples is still the wrong hat until it's sized and shaped correctly. Use the hat sizing guide, or better yet, come in so we can measure and shape it properly.
It is not a style guide. Cattleman, Gus, open crown, pinch front — those choices come from face shape, lifestyle, and preference, not from the X on the label. Start with hats and your face shape and your head shape, then pick the felt quality that matches how you'll wear it.
And it is not a substitute for care. Even the finest beaver blend will look tired if it lives crumpled in a back seat. Brush it. Store it on a form or rack. Bring it in when it needs a real cleaning.
How to choose the right X for you
First felt hat / daily driver: A quality 4X–10X range is where most people should start. You'll get real fur felt performance without overspending before you know your preferred style. Hats like the Resistol Tucker, Stetson Oak Ridge, Stetson Red Rocks, and Stetson Corral are strong places to begin — then size them right.
All-weather, frequent wear: Lean toward mid to upper mid X from a brand you trust. You'll feel the difference in hand and in how the hat holds its set.
Special occasion or heirloom: Step up. Higher X shines when the hat will be shaped once, worn for years, and maybe handed down.
Budget still matters — and so does honesty. We'd rather put you in the best-fitting mid-range hat than talk you into a premium number that sits wrong.
Come feel the difference
Reading about X-ratings helps. Holding two hats in your hands settles the question faster.
