Rael
Rael's sizing and absorbency, translated onto the same scale as every other brand - so you can shop it (or leave it) with a fair comparison.
How Rael sizing runs
Rael’s product page and size guide both say "When in doubt, size up!" It makes no runs-small or runs-large claim; the size-up guidance is its only direction.
| Size | Hip | Waist |
|---|---|---|
| Small (reusable, numeric 0-2) | 34–36" | 24–26" |
| Medium (reusable, numeric 2-4) | 36–38" | 26–28" |
| Large (reusable, numeric 4-8) | 38–40" | 28–31" |
| X-Large (reusable, numeric 8-10) | 40–42" | 31–33" |
| XX-Large (reusable, numeric 10-16) | 42–44" | 33–37" |
| S/M (disposable, pant size 0-14) | — | 24–38" |

Rael catalog (1)
Rael's own store no longer lists its reusable boyshort, so nothing here is in stock at the brand. Amazon still carries it, and the Search Amazon link goes there.
