If this has already been addressed, please forgive me:
Looking like it is tres expensive, but also very warm for its weight. ~41.41% down to weight ratio! Ala a custom GooseFeet parka from Ben, but from a mainstream manufacturer. Intriguing at the very least with box wall construction and fairly full features like alpine cuffs, hand warmer pockets and interior drop in pockets.
Edit: Specs from MB:
[Weight] 12.8 oz. (Size M)
[Fill Weight] 5.3 oz.
