Sizing
Modibodi publishes no runs-small or runs-large guidance (order your usual size by hip); Aisle is one many people size up in. 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: Modibodi publishes no runs-small or runs-large guidance. Its size guide says measurements refer to your body, not the product, and that hip is the measurement that matters most.
Aisle: Aisle says to size up if you are between sizes on briefs and hipsters, and that the 1X is roomier through the waist than the XL. Its thongs run large in 1X and 2X, so Aisle recommends sizing down for those. Aisle sizes off the widest part of the lower hip and publishes no waist measurement.
Quick answers
- Is Modibodi or Aisle more absorbent?
- By their own published claims, Modibodi reaches a higher maximum capacity (up to 50 mL) than Aisle (up to 40 mL) at its highest current tier. That does not make every Modibodi pair more absorbent than every Aisle pair - it means the top of Modibodi's range is higher. Compare tier by tier in millilitres, not by the label words. These are saline-lab maximums, not leak-free guarantees; the one test with real blood (BMJ 2023, three pairs of one brand) measured a few millilitres before pooling, a different measurement from a claimed maximum.
- Do Modibodi and Aisle use the same absorbency labels?
- No. Modibodi publishes 3 current tiers (20–50 mL across the range) and Aisle publishes 4 current tiers (5–40 mL across the range). 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 Aisle sizes compare?
- Modibodi publishes no runs-small or runs-large guidance (order your usual size by hip); Aisle is one many people size up in. 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.
- Is Modibodi or Aisle better?
- Neither is better across the board - they differ on measurable things. Compare three numbers on this page: the millilitres at the tier you actually need (not the tier names), how each brand's sizing runs for your hip measurement, and current prices in the catalog. The right brand is the one whose numbers fit your flow and your body, and that answer differs by person.
