DESCENTE to GU size
The short answer
DESCENTE L is GU M by the two brands' own charts. 4 of 6 DESCENTE sizes land on a different label at GU.
Both brands publish the body chest each size is cut for, so every row matches a chest, not a letter.

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.
