Custom Merch for Schools and Clubs in Seattle, WA
Merch Mob makes spirit wear, team orders, and class and graduation shirts for schools and clubs in Seattle, WA, at its shop in Montclair, CA, and ships them to Seattle. Just 10% of Seattle residents 3 and older are in K-12 school, well under 17% nationally and against 16% statewide (Census ACS, 2020-2024), so alumni, staff and parents may buy as much spirit wear as students, and adult sizes need depth.

What Seattle's weather means for schools and clubs
Average highs stay under 65°F from October to April, which covers most of the school year, so lead every spirit wear order with fleece and treat tees as the add-on. Short sleeves fit June to September, when highs average 70°F or more and the year's handful of hot days arrive (about 3 days at 90°F or above), so summer camp shirts can be light tees and the rest of the order long-sleeve. December averages a high of 48°F, chilly weather for outdoor practice, so a warmup jacket or a fleece-lined hoodie is worth adding to team orders. About 30 nights a year reach 32°F or below, mostly in the heart of winter, so a hoodie and a beanie cover the coldest evening games. Rain peaks in November at about 5.8 inches, so any team that plays outdoors that month needs a layer that sheds water, and spirit wear sales can move under cover.
