2XU to POPFLEX leggings size

The short answer

2XU XL is POPFLEX L by the two brands' own charts. 1 of 6 2XU sizes land on a different label at POPFLEX.

Both brands publish the body waist each size is cut for, so every row matches a waist, not a tag.

Every 2XU Flex & Fluid Tights size read across to POPFLEX. Letter sizes on the left, Letter on the right.

Tinted rows change label or sit between two sizes. Read from the two charts only; no formula and no averaging.
