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. Aisle publishes its capacity in millilitres (two tiers grade A), and its Boost insert takes one pair from about 20 to 40 mL. Sizes run XXS to 5X. A values-driven pick with a clear, adjustable capacity story rather than the highest ceiling.
Best for
Shoppers who like a long-standing reusable-first brand, adjustable capacity, and figures stated in millilitres.
Skip if
You want the highest claimed ceiling.
What stands out

Trade-offs
- Top capacity of about 40 mL, below the highest ceilings here
How Aisle sizing runs
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.

| XS | 35–36" | — |
| S | 37–38" | — |
