2XU to Gymshark leggings size

The short answer

2XU M is Gymshark M or S by the two brands' own charts. 0 of 6 2XU sizes land on a different label at Gymshark.

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 Gymshark. Letter sizes on the left, Letter on the right.
