Custom Merch for Gyms in Philadelphia, PA
Merch Mob makes member tees, coach and staff apparel, and challenge and competition shirts for gyms in Philadelphia, PA, at its shop in Montclair, CA, and ships them to Philadelphia. Young adults make up 28% of Philadelphia, against 23% nationally (Census ACS, 2020-2024); that age group wears gym apparel outside the gym too, so the design should hold up as everyday wear.

What Philadelphia's weather means for gyms
July highs average 89°F in Philadelphia, with about 40 days a year at 90°F or more, so a tank and a light tee lead the summer rack before fleece takes over. Even January, the coolest month, averages a high of only 42°F, so a crewneck or midweight hoodie is a winter staple and worth a reorder by midseason. With about 51 inches of rain and melted snow a year, a quick-drying training tee earns its place over cotton for members who run or train outside between showers. About 23 inches of snow fall in a typical year, enough to move outdoor sessions inside for stretches of winter and make a long-sleeve challenge shirt worth planning. About 62 nights a year drop to freezing or below, which keeps a beanie and a crewneck on the front desk through winter.
