What “All Day” means here

Thinx's All Day tier holds 100 mL Data quality grade A, brand publishes mL by the brand's own published claim ('holds up to 12 regular tampons' worth... up to 100 mL' (thinx.com/pages/how-they-work, verified 2026-06-10); All Day PDPs state 'Absorbent layers hold up to 12 regular tampons worth' (re-verified 2026-06-11) - an implied 8.3 mL/tampon basis that matches neither the common 5 mL nor Thinx's own blog's 6-9 mL definition).

Over two years

This pair

$40

once - built to last about two years with normal care (the brand's own guidance).

Disposables

$120 to $288

over the same two years, at $5 to $12 a month - a commonly cited range.

A reusable pair only replaces disposables on the days you actually wear it, so your real saving depends on how often you reach for it. The more you do, the further a one-time $40 goes against a monthly cost. These are illustrative figures you can adjust, not a measured PeriodFinder number.
