Proof (Proof by Always) Super-Light in every brand's language
By Proof (Proof by Always)'s own published claim, its Super-Light tier holds 5 mL Data quality grade B, converted from tampon counts. Tier names don't transfer between brands - millilitres do. Here is the smallest tier in each other brand whose claimed capacity covers it.
The source claim
Proof (Proof by Always) Super-Light: up to 1 light tampon
The covering tier in each brand
“Covering” means the smallest tier whose claimed maximum meets the middle of Proof (Proof by Always) Super-Light's range (5 mL). Grades: A = brand publishes mL, B = converted from counts at a stated basis, C = conflicting or unconfirmed.
| Brand | Covering tier | Claimed capacity | Grade |
|---|---|---|---|
| Knix | Light | 5–15 mL | Data quality grade B, converted from tampon counts |
| Thinx | All Day | 100 mL | Data quality grade A, brand publishes mL |
| Modibodi | Light | 20 mL | Data quality grade A, brand publishes mL |
| Saalt | Light | 10 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 | Light (Thong) | 10 mL | Data quality grade B, converted from tampon counts |
| Bambody | High Absorbency | 10 mL | Data quality grade C, conflicting / unconfirmed claim |
| Aisle | Essential Thong (Light) | 5 mL | Data quality grade B, converted from tampon counts |
| WUKA | Light | 7 mL | Data quality grade C, conflicting / unconfirmed claim |
| Rael | Reusable Boyshort | 15–25 mL | Data quality grade C, conflicting / unconfirmed claim |
| Hanky Panky | Light | 10 mL | Data quality grade B, converted from tampon counts |
| Skims | Period Panties Thong | 10 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.
