Custom Merch for Events in San Diego, CA
Merch Mob makes attendee and souvenir tees, staff, crew and security shirts, and volunteer shirts for events in San Diego, CA, at its shop in Montclair, CA, and ships them to San Diego. The 18-to-34 share is 30% in San Diego, against 23% nationally and 24% across California (Census ACS, 2020-2024), so design attendee merch to be worn again, with strong art rather than a sponsor list on the front.

San Diego by the numbers
San Diego has 1,406,106 residents, up 1.6% since 2020 (Census estimates).
San Diego County has 108 event promoters (performing arts, sports and similar events) with paid employees (Census County Business Patterns, 2023). That is 0.33 for every 10,000 residents, above the national figure of 0.27. 76% of them employ fewer than 10 people. The count is up 27% from 85 in 2018.
That counts promoters with a payroll; one-off events run by volunteers or venues are not in it.

What San Diego's weather means for events
From a 67°F average high in January to 82°F in August, San Diego weather lets outdoor events run in any month, so the staff tee can stay the same all year. Booth hoodies matter mainly after dark, when December lows average 45°F, so size the fleece run to night shows and keep daytime stock in tees. With weather this steady, booth stock can be planned from ticket sales and past events rather than the forecast, and leftover undated tees carry over to the next date. With roughly 11 inches of rain a year, rainouts are rare and sun is the bigger planning issue, so caps for staff and attendees belong in the order.
