Here’s an old item from ERA3 Apparel & Hardgoods via Dickies Workwear. Known as the Speed Shop Insulated Jacket, as far as I can gather they just had one batch of these made and all in massive sizes for style reasons.
It’s a heavy duty working jacket with a pretty beefy and old school (almost steam punk) brass zip. Simple construction on the outside, big buttons for coarse adjustment at the waist and on the cuffs, pen pocket on one sleeve and 2 standard slash pockets on the front. Inside has the quilted look to it with cross pattern stitching retaining the light insulation.
Obviously the main event is the imposing embroidered artwork that’s so big and uses so much thread that the back of the jacket stays pretty much rigid even when hung on a hook. Quite a lot of automated machine time went in to that piece.
