Gap to Arc'teryx clothing size

The short answer

Gap 16 is Arc'teryx L or XL by the two brands' own charts.

Both brands publish the body bust each size is cut for, so every row matches a bust, not a letter or a number.

Every Gap size read across to Arc'teryx. US sizes on the left, Letter on the right.

Tinted rows change label or sit between two sizes. 3 sizes have no counterpart on the Arc'teryx chart. Read from the two charts only; no formula and no averaging.

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.
