Sizing
Modibodi has no single consistent sizing direction; Knix tends to run small (many people size up). Both brands size from your hip measurement, so rather than converting one brand's size into the other's, the size finder gives you your size in each directly.
Modibodi: Could not verify. No Modibodi-owned source (size guide or support FAQ) states whether sizing runs small, large, or true-to-size. The size guide notes only that measurements "refer
Knix: Brand labels core styles "True to Size" on product pages (e.g. Essential High Rise). However, customer reviews consistently report the leakproof styles run small / recommend sizing
Quick answers
- Is Modibodi or Knix more absorbent?
- By their own published claims, Knix reaches a higher maximum capacity (up to 99 mL) than Modibodi (up to 50 mL) at its highest current tier. That does not make every Knix pair more absorbent than every Modibodi pair - it means the top of Knix's range is higher. Compare tier by tier in millilitres, not by the label words. And remember these are saline-lab maximums, not leak-free guarantees - the only blood-component study measured far lower real capacity.
- Do Modibodi and Knix use the same absorbency labels?
- No. Modibodi publishes 3 current tiers (20–50 mL across the range) and Knix publishes 4 (15–99 mL). Even where the words overlap, the millilitres differ, which is exactly why this page compares them in millilitres with a data-quality grade on every number.
- How do Modibodi and Knix sizes compare?
- Modibodi has no single consistent sizing direction; Knix tends to run small (many people size up). Both size from your hip measurement, so the size finder gives your size in each brand directly rather than guessing from the other brand's number.
