Just wrapped up a project that I've been thinking about for a long time: a padded 2-layer hood attached to a butterfly straitjacket. I classified this among the "not likely to be done any time soon" project sketches, as it was going to be difficult to make, as well as challenging to wear.
The no-compromise design includes a rear lacing-only entry, which makes getting into and out of the jacket a time-consuming task. I didn't add a zipper for speed or convenience.
The hood, which is essentially an inner and outer hood with a foam layer in between, creates a real buffer between the wearer and the outside world. Best used when the weather isn't too hot.
The breathing tube is another aspect that makes the restraint even more intense. If you forget to mouth-breathe and try to breathe through your nose, the leather will just press against your face and remind you just how stuck you really are.
Finally, the arm pockets are pared down to create the tightest fit yet. I'm always trying to find the trade-off/boundary between tightness and comfort, and we may just about be there. It looks fantastic in real life. I'm so very happy with it, and the testing sessions are going much better than expected.
