Merch Mob makes fundraising tees and hoodies, volunteer shirts, and walk, run and ride shirts for nonprofits in Louisville, KY, at its shop in Montclair, CA, and ships them to Louisville. At 37.7, the median age in Louisville 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 Louisville's weather means for nonprofits
Average highs reach 70°F only from May to September here, so long sleeves suit more of the event calendar than tees do, and a summer race is the main exception. The coldest stretch, January, has average highs under 45°F, so winter volunteers need real fleece, and a beanie or heavy hoodie is a thank-you that gets used. Spring and fall give Louisville its easiest outdoor event dates, between the summer peak in July and the chill of January, so plan the main walk or run for one of them. About 13 inches of snow fall in a typical year, enough that a winter date can be snowed out, so give any outdoor holiday drive a backup date and keep spare volunteer hoodies at check-in. With about 80 nights a year at or below 32°F, early-morning volunteers in the cold months need a warm layer, so budget a hoodie or fleece for the setup crew as well as the event tee.
