The Moncler x Piccioli collection is designed by Valentino head Pierpaolo Piccioli, and features dramatic hooded, floor-length takes on your standard sleeping bag coat. It is part of the storied Italian winter wear label's "Genius" initiative, which also features collaborations with seven other auteurs, including Simone Rocha. (After several celebrity endorsements, those designs have sold out quickly too.)
It's only mid-December, and puffer mania may have already peaked. While there are only slim pickings on the Moncler website, if you're worried your winter wardrobe isn't extravagantly insulated enough, there are still a few Moncler x Piccioli dresses left at Barneys.
