Aisle
Aisle'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 Aisle
The Canadian reusable-first original, with a distinctive numeric sizing system and lower claimed capacity than the heavy-flow leaders. A values-driven pick, not a maximum-absorbency one.
Best for
Shoppers who like a long-standing reusable-first brand and light-to-moderate coverage.
Skip if
You want the highest capacity, or a familiar alpha size (Aisle uses numeric sizing).
What stands out
- A long-standing reusable-first brand
- Distinctive, well-documented numeric sizing
Trade-offs
- Lower top capacity (about 40 mL) than the heavy-flow leaders
- Numeric sizing takes a moment to map to your usual size
How Aisle sizing runs
Brief & Hipster: "Between sizes? We recommend sizing up." Between XL and 1X, the 1X is roomier through the waist. Thongs run LARGE in sizes 1X and 2X, so Aisle recommends sizing DO
