Ein, flex design said you can lightly spot wash, but recommend hitting it with febreeze. :/
I'm hoping the gel cooling pads aren't going to prespire as much as some of the vests I've seen on Amazon that take water packs. Hoping to figure out something, or this will be a winter only costume.
Also best of luck on the contest, you got my vote.

A bit of an update, and a minor disaster to my costume....

I finished up the boots, vintage motorcycle with added chain and Ein's toecap print. I glued everything down with E6000. I'm not 100% happy with how the bike chain turned out, mine ends significantly shorter than the film boots. Unfortunately if I had gone any longer with the chain it would not curve up with the sole of the boot. Any other Joe's have a solution to this problem? I'm debating casting the chain in something more plyable and gluing it on. That may hold better in the long run.
As for the little disaster... My chest piece near the top where it's thinner from trying it on and drilling the small holes for the badges, had a little unsightly crease near the top middle.
Stupidly I thought a little pressure and warmth from my heat gun on low would fix this in retrospect minor eyesore. I did not realise near the minor defect was a very small crack. As soon as the heat hit it the crack became a small but noticeble pencil sized hole. An hour later of frantically trying to fix my mistake and I only made things worse...

Ugh... I already contacted Logan about ordering a replacement. Still a bit of a bummer.
