Custom Merch for Events in Irvine, CA
Merch Mob makes attendee and souvenir tees, staff, crew and security shirts, and volunteer shirts for events in Irvine, CA, at its shop in Montclair, CA, and ships them to Irvine. The 18-to-34 share is 30% in Irvine, 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.
Irvine by the numbers
Irvine has 318,764 residents, up 3.6% since 2020 (Census estimates).

What Irvine's weather means for events
August is the month to watch for outdoor events in Irvine: it averages a high of 87°F, and about 35 days a year reach 90°F, so summer daytime dates need caps, shade and light staff shirts. Night events still turn cool, with December lows averaging 43°F, so stock booth hoodies for anything that runs after dark. Most outdoor dates need no rain plan, but February averages about 3.4 inches, so an event that month should have a tent plan and covered storage for booth stock. With roughly 14 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.
