Knix
Knix'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.
Our take on Knix
The mainstream heavyweight: the widest catalog we track and the highest verified capacity tier, at prices spanning budget multipacks to premium. The catch is a PFAS settlement in its history, so check its current testing.
Best for
Shoppers who want the most choice and genuinely high capacity from a familiar US brand with frequent sales.
Skip if
You are specifically avoiding brands with a PFAS history, or you want the lowest possible price.
What stands out
- Highest verified capacity tier of any brand here (Ultra, up to about 99 mL)
- The largest live catalog we track - 100+ styles across cuts and absorbencies
- Wide price range, with inexpensive multipacks alongside premium styles
Trade-offs
- Settled a $1.4M PFAS class action and agreed to drop unsupported "PFAS-free" claims (see the note above)
- Its leakproof styles are widely reported to run small, so size up
- So many styles that narrowing down takes some filtering
Knix and PFAS: an honest note
Knix settled a class action for $1.4 million over PFAS-related marketing, and agreed to stop calling its products "PFAS-free," "toxic-chemical-free," or "fluorine-free" without support, plus two years of increased PFAS testing. Knix did not admit wrongdoing.
What the lawsuits and testing did and did not establishHow Knix sizing runs
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
| Size | Hip | Waist |
|---|---|---|
| S | 33–37" | 23–27" |
| M | 38–41" | 28–31" |
| L | 42–44" | 32–34" |
| XL | 45–47" | 35–37" |
| XXL (2X) | 48–50" | 38–40" |
| XXXL (3X) | 51–53" | — |
| XXXXL (4X) | 54–56" | — |
