Custom Merch for Nonprofits in Washington, DC
Merch Mob makes fundraising tees and hoodies, volunteer shirts, and walk, run and ride shirts for nonprofits in Washington, DC, at its shop in Montclair, CA, and ships them to Washington. A median age of 34.9, against 38.9 for the US (Census ACS, 2020-2024), puts Washington on the younger side, so offer the tee in a modern fit and add a hoodie as the higher-priced item younger supporters will buy.

What Washington'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. Average highs stay under 65°F from November to March, so cold-season volunteer days need long sleeves, and a fleece thank-you gets worn right away. Spring and fall give Washington 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 14 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. About 60 nights a year fall to 32°F or below, so a volunteer crew that sets up before sunrise in winter should have a beanie and a layer over the event tee.
