Merch Mob makes fundraising tees and hoodies, volunteer shirts, and walk, run and ride shirts for nonprofits in Los Angeles, CA, at its shop in Montclair, CA, and ships them to Los Angeles. At 37.2, the median age in Los Angeles sits a little under the national 38.9 (Census ACS, 2020-2024), so supporters span every age; a unisex tee in a full size run, plus youth sizes for families, covers most of them.

What Los Angeles's weather means for nonprofits
Heat is occasional rather than constant, with roughly 26 days a year at 90°F or more, so a moisture-wicking shirt is worth it for a summer race, and cotton works for the rest of the calendar. Winter barely chills the nights here, with December lows averaging 48°F, so a crewneck or quarter-zip is about as heavy as a donor gift needs to be. Tees carry most volunteer days here: 9 months average a high of 70°F or more (March to November), and a long sleeve covers the rest. Rain dates are seldom needed with about 14 inches of rain in a typical year, so sun is the thing to plan for: add a cap to the volunteer kit.
