Joe,
Not too sure where to recommend for blazers... Our museum security department has the option to wear a core soft shell jacket (for indoors/outdoors). It’s comfy, black, and has big internal pockets and two external pockets with zippers.
Wish I could help more, but I wish you luck on your search!
