Nike to Zella leggings size
The short answer
Nike XXL is Zella 2X by the two brands' own charts. 5 of 11 Nike sizes land on a different label at Zella.
Both brands publish the body waist each size is cut for, so every row matches a waist, not a tag.
On 1 sizes the charts land two or more sizes from the same label. Brands do not measure the body the same way, so on those rows treat the chart answer and the same label as the two ends of a range.
