Napa County. Which means that neighboring Sonoma County is completely inaccessible, but I can reach the BART system and visit San Fran as a day trip.
I just wrote a super long response and then re-read your post and realized you're not interested in scuba lessons but buying gear. I know I read it but I got distracted. hah!
Anyway, I have heard of Pinnacles and of Marin Diving Center. I believe they are quite popular for that area. It might be worth trying to get to. At the very least, give them a call and tell them what you're looking for in a suit and your needs (freediving vs scuba vs surfing). If you decide to visit SF, Bamboo Reef is accessible as it's a few blocks from BART and would require a nice walk or a private car hire. It's really close to the CalTrain station (of course BART and CalTrain doesn't meet up in SF as that would only make SENSE!).
The shops like Pinnacles and Marin as well as Bamboo reef might have photos posted online of their brick and mortar offerings. Again, give them a call.
A lot of people have been diving and taking lessons due to covid. However, keep in mind that neoprene production took a hit during the pandemic and a lot of things are simply out of stock and will take some time to bring in. When and if you do call, try and be a bit more specific with what you need and sizing. You might also ask what kind of brands/styles they carry so you can take notes and look up size charts, etc onilne before making the journey.
