Custom Merch for Companies in Chicago, IL
Merch Mob makes onboarding kits, everyday staff apparel, and field and customer-facing uniforms for companies in Chicago, IL, at its shop in Montclair, CA, and ships them to Chicago. Chicago skews younger than the country, with a median age of 35.8 next to 38.9 nationally (Census ACS, 2020-2024), so a soft hoodie, a heavyweight tee and a cap are the onboarding pieces most likely to be worn outside work.

What Chicago's weather means for companies
With 3 months of average highs below 45°F (December to February), staff in Chicago live in outerwear for a good part of the year, so put the budget into a jacket people will wear on the commute. Summer heat is real too, about 20 days a year at 90°F or more, so outdoor events from May to September need lightweight tees and caps, and field crews need a breathable polo. January lows average 19°F, so a heavyweight hoodie or beanie makes a year-end gift that gets worn the week it arrives. With roughly 39 inches of snow in a typical year, give field and delivery staff a hooded, water-resistant jacket, since fleece alone soaks through on snowy days. Temperatures drop to 32°F or below on about 106 nights a year, so an onboarding kit for a winter hire works better with a warm layer, such as a fleece quarter-zip, than with a tee alone.
