Yesterday in my meeting with Jeremy Koreski, I noticed he was wearing this black Nano Puff Jacket from Patagonia. It's a great piece of technology as it's wind, waterproof and warm– an absolute necessity for winters here on the cold, wet and damp west coast. Made of Patagonia's unique ultralight ripstop recycled polyester shell fabric, it also has lightweight PrimaLoft One insulation which means it's ready for the intensity known here on the coast. If you happen to reside further inland, this piece would work well as a mid layer in the snow under a parka or over a sweater. The insulation is held in place cleverly through the simple quilt pattern of the jacket. I would easily see myself wearing this over an oxford and tie, some trousers or denim and a nice pair of boots.
