sorry to be a bit of a kill joy, but many people, who make the under armour core, then end up making it out of foam, si i reccomend making it out of foam EVA mats, and i have seen a few people get the under core almost finished before they change their mind.
other than that punch in the face, everything else is looking pretty dam good, and seems to fit you rarther well, and i think i can now no longer moan about it being to cold here.
have you though about a custom paint job, e.g. a winterised camo?
