For those of you that conceal carry on the jobs -- what kind of indoor winter upper garment do you sport that won't print when bending over, reaching up etc.?

During summer with longer T-Shirt outside the waste-band, the fabric seems to flow easy enough.
Other than t-shirt wrapping behind the weapon, or butt of mag printing during high degree bending, it's been undetectable.

All my company cold weather sweatshirts are somewhat tight as I don't want to snag on brackets, racks, door jambs, etc.
I'm looking into new style of winter (indoor) garment and figured I'd ask you folks for what works for you.
