Merch Mob makes printed jerseys, practice shirts, and warmups and team hoodies for sports teams in San Francisco, CA, at its shop in Montclair, CA, and ships them to San Francisco.

What San Francisco's weather means for sports teams
With 7 months a year averaging highs under 65°F, half the calendar or more is warmup weather in San Francisco, so a hoodie or quarter-zip belongs in every player's order, not just the coaches'. Tee weather is short, with average highs of 70°F or more only from September to October, so long-sleeve practice shirts get more use than short sleeves over a full year. In January, when highs average 58°F, practice calls for a long sleeve or a performance base layer under the team tee. Rain peaks in December at about 4.8 inches, so teams playing then need practice gear that dries fast and a water-resistant jacket for the bench.
