For western/cowboy hats, the "X" is a quality indicator.
General rule: the more X's, the higher the quality of materials and finish — but the scale is not universal: comparisons are mainly made within the same brand.
| Indication | Composition / typical properties | For whom? |
|---|---|---|
| 4X | Often wool (or blends). Good balance of durability/price. | Regular use, controlled budget. |
| 5X – 8X | Fur (rabbit/hare). Increased density, hold and comfort. | Superior longevity, more refined finish. |
| 10X and + | Entry and rise of beaver (finer fiber, better water resistance). The exact percentages vary and are sometimes kept secret. | High-end finish, silky touch. |

The "X" no longer concern furs, but the fineness/tightness of the weaving and the quality of the fiber. The finer and more regular the weaving, the higher the X index rises (internal scale for each brand).
No, because there is no common standard. Compare your X's within the same brand. :contentReference[oaicite:3]{index=3}
Within the same brand, generally yes for the quality of materials and resistance to wear/water. Stay attentive to the cut and usage. :contentReference[oaicite:4]{index=4}
These are very high-end series specific to certain brands; the numbers are not comparable between manufacturers. :contentReference[oaicite:5]{index=5}
