Bambody Heavy Flow in every brand's language
By Bambody's own published claim, its Heavy Flow tier holds 20 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
Bambody Heavy Flow: Hipster Heavy Flow product page: 'The 4-layer bamboo construction absorbs up to 4 regular tampons' worth of fluid'. The High Waist ('up to 4 tampons-equivalent') and Brief ('holds up to 4 regular tampons worth of fluid') pages state the same figure and join this row. Converted at the brand's own 5 mL per tampon (bambody.com, read 2026-09-20).
The covering tier in each brand
“Covering” means the smallest tier whose claimed maximum meets the middle of Bambody Heavy Flow's range (20 mL). Grades: A = brand publishes mL, B = converted from counts at a stated basis, C = conflicting or unconfirmed.

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.
