R13D1 is the first ever insulated Shirt-1. Combining our regular, most longstanding shirt with the technology and detail of our Down-Series. D1 is our regular shirt filled with ethically farmed [raised for meat / no live plucking] European silver goose down. Cleaned and processed in Japan by Kawada feather, this down retains its original mottled colour, as no bleach is used. 90% down mixed with 10% feather [to reduce clumping], this product has a fill-power rating of 850. To show the down's unique colour this garment is lined with a transparent 100% nylon micro-ripstop developed by Toray.
