To echo others, a summer gun check, of the typical tan variety or a muted blue. Some suggestions below. I think the key to a good gun check is to avoid too many contrasting colours.
Would also be interested in a light blue / mid blue, large scale glen plaid.
FWIW, while I know 3r2 jackets are popular here, I hope there continue to be two button only jacket offerings.
