Yeah, this sounds insane, and perhaps I am. But I realized the other day that I own too much grey, and I love my Thermawrap, so I'm hoping someone else might want to trade. I've got a Large Thermawrap Parka in Gunmetal Grey in very good condition, the only bad thing going for it is that there's a little bit of piling on the stretchy part of the cuffs. Otherwise in great shape.
If anyone has a size Large Thermawrap Parka (the older one, not the newer "Pro" model that's heavier) in blue or another color (I forget what else it came in), let me know!
