Sizes
Jerseys - As a general rule, Japanese replica baseball jerseys tend to be about one size smaller than their North American counterparts - so if you normally take a medium, for example, you should order a large. The chart below should give you a rough idea of your correct size, but as manufacturers' sizes vary, there is also a size guide for some jerseys (as links from the product descriptions).
Men's chest (inches) | Men's waist (inches) | American size | Japanese size |
| 38-40 | 30-32 | S | M (medium) |
| 40-42 | 32-34 | M | L (large) |
| 42-44 | 34-36 | L | LL (extra large) |
Caps - Our caps come from various sources and as a result sizes can vary, depending on the manufacturer. All replica and throwback caps are adjustable, with a range of head sizes covered within each cap size. The only fitted caps we sell are the 59FIFTY New Era caps. The chart below should help you determine which size you need.
