What Thinx publishes now
As of 2026-06-11, Thinx's main styles (All Day, All Night, and the Teens line) print the same blanket claim: "up to 12 regular tampons (or 3 regular pads') worth," which the brand's how-they-work page frames as up to about 100 mL. That 100 mL figure is a single maximum applied across those styles, not the rating of a tier called "Super."
Thinx's classic per-tier ladder - Light up to Super, where Super was about 5 regular tampons (roughly 45 mL) - no longer appears in its current product marketing. So an answer that says "Thinx Super holds 100 ml" is welding the old tier name to the new blanket number. The honest version: Thinx's current styles claim up to ~100 mL; the old "Super" tier was ~45 mL and is not how Thinx markets today.
And the number is a claim, not a guarantee
Either way, 100 mL is a saline-test maximum. The only published study with real blood components (BMJ Sexual & Reproductive Health, 2023) measured the period underwear it tested holding about 1 to 3 mL before leaking. Read 100 mL as the top of Thinx's claimed range for comparison, not as how long a pair keeps you dry.
Quick answers
- Does Thinx still have a "Super" absorbency?
- Not as a separately marketed tier on its main styles. Thinx's current product pages print one blanket "up to 12 regular tampons / up to ~100 mL" claim rather than the old Light-to-Super ladder, where Super was about 5 regular tampons (~45 mL). If you see "Thinx Super = 100 ml," it is mixing the retired tier name with the current flagship number.
- How many tampons is Thinx?
- Thinx's current main styles claim up to 12 regular tampons (about 100 mL) as a maximum. Remember that "regular tampon" is not a fixed amount - the FDA range is 6 to 9 grams and brands count differently - so compare in millilitres, and treat the figure as a saline-test maximum, not a leak-free promise.
