Ask the MB: Big-Time Winter Coats
A: Puffy coats are definitely not out. Moncler made some of the earliest versions, and the Italians deemed them worthy for the initial ascent of K2 in 1954.
However, if you don't have an extra $900-$1000 lying around we really, really like the Spiewak N3B Snorkel Parka (also developed in the '50s) and it's just $164.95. Yeah, it is a little overkill for your garden-variety winter weather, but a good defense when Jack Frost is nipping at your nose like a pit bull trained by Michael Vick.
