I wish it was that simple. Even if a company has a HQ in the USA, do they manufacture it themselves or contract it out. Even if they manufacture locally, they need to order the material from a foreign manufacturer in many cases. High density Yamamoto neoprene from Japan for example.
Bare, now owned by Huish Outdoors, has its' HQ in Salt Lake City and the repair center in Vancouver B. C, just across the Canadian Border from Seattle where I live. Yet the manufacturing plant, while in-house, is in Malta.
I think he is more referring to no US affiliation what so ever. With that said let's focus on the OP's question ultimately where he spends his money is entirely up to him.
