Moncler Maya Down Jacket Black10 10 Brand new with tags. Measurements To understand how the Moncler sizes work, we recommend that size 2 is small, 4 is large & 5 is Extra Large. Someone who is around 6ft and 90kg will find that both a size 4 and 5 fit although the 4 is a little more fitted. Go for a smaller size if you like a more fitted down jacket. Bear in mind the pit to pit's are external measurements so 1" should be removed for an accurate fit. Size 2 (S M) Pit to Pit: 22"
