Rael Reusable Boyshort in every brand's language
By Rael's own published claim, its Reusable Boyshort tier holds 15–25 mL Data quality grade C, conflicting / unconfirmed claim. Tier names don't transfer between brands - millilitres do. Here is the smallest tier in each other brand whose claimed capacity covers it.

The covering tier in each brand
“Covering” means the smallest tier whose claimed maximum meets the middle of Rael Reusable Boyshort's range (15–25 mL). Grades: A = brand publishes mL, B = converted from counts at a stated basis, C = conflicting or unconfirmed.

|---|---|---|---|
| Knix | Moderate | 18–36 mL | Data quality grade C, conflicting / unconfirmed claim |
| Thinx | All Day | 100 mL | Data quality grade A, brand publishes mL |
| Modibodi | Light | 20 mL | Data quality grade A, brand publishes mL |
| Saalt | Heavy | 20 mL | Data quality grade B, converted from tampon counts |
| Proof (Proof by Always) | Heavy | 20 mL | Data quality grade B, converted from tampon counts |
| Ruby Love | Period underwear (one level) | 12.5 mL | Data quality grade B, converted from tampon counts |
| The Period Company | Medium | 20 mL | Data quality grade B, converted from tampon counts |
| Bambody | High Absorbency | 10 mL | Data quality grade C, conflicting / unconfirmed claim |
| Aisle | Essential Brief/Hipster/Boxer (Moderate) | 20 mL | Data quality grade A, brand publishes mL |
| WUKA | Heavy | 20 mL | Data quality grade A, brand publishes mL |

| Skims | Period Panties Brief | 15 mL | Data quality grade B, converted from tampon counts |
All figures are the brands' own maximum-capacity claims, normalized to millilitres - claims made comparable are still claims, not lab measurements (the only blood-component study, BMJ Sexual & Reproductive Health 2023, measured far lower effective capacity than marketing figures). Sources, conversion rules, and verification dates live in the methodology.
