I still have my woobie(s). Usually, two sewn together for an all-season sleep kit. And as you all will recall, I ventured into the woobie smoking jackets a while back. I've since moved on to my own design. No woobies were harmed or desecrated in the creation of my new concept. I use 3 separate layers to make these. This baby is currently lined with 2.5 oz APEX Climashield. With nothing more than a T-shirt on in a snow storm last winter, it was relatively light and extremely warm. And yes, that hood is a modular attachment.
However, looking at my source for materials, they're out of APEX so I may have to look at Primaloft for future projects.
