Arc'teryx to Nike clothing size
The short answer
Arc'teryx XS is Nike S by the two brands' own charts. 1 of 6 Arc'teryx sizes land on a different label at Nike.
Both brands publish the body bust each size is cut for, so every row matches a bust, not a letter or a number.

What wearers say
Charts describe a garment, not a fit. We do not collect fit reports for this category yet, so this table is the two brands' own claims and nothing more.
