Custom Merch for Gyms in Baltimore, MD
Merch Mob makes member tees, coach and staff apparel, and challenge and competition shirts for gyms in Baltimore, MD, at its shop in Montclair, CA, and ships them to Baltimore. The 18 to 34 age group is 27% of Baltimore, a few points over the national 23% and against 22% across Maryland (Census ACS, 2020-2024), so give training cuts a little more room than a typical gym would.

What Baltimore's weather means for gyms
July highs average 90°F in Baltimore, with about 43 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 44°F, so a crewneck or midweight hoodie is a winter staple and worth a reorder by midseason. Between the tank months and the hoodie months, a long-sleeve tee or quarter-zip sells best, so keep one in the core range all year. About 19 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 52 nights a year drop to freezing or below, which keeps a beanie and a crewneck on the front desk through winter.
