What Chicago's weather means for sports teams
Chicago spends December to February with average highs below 45°F, so fall and winter team orders need warm layers: heavy hoodies, insulated sideline jackets and beanies for players and fans in the stands. Summers turn hot as well, with about 20 days a year at 90°F or more, so teams that play from May to September need wicking practice tees and caps on top of the winter layers. Hoodie weather, with average highs under 65°F, lasts 7 months, so warmups are the most-worn piece in the kit and deserve the better fabric. About 39 inches of snow fall in a typical year, so spring seasons often open in cold weather and fall seasons close in it; long sleeves and a warm layer belong on both orders. With about 106 nights a year at or below freezing, frost often still covers the field at weekend morning games, so a thermal long sleeve under the jersey earns a place in each player's kit.

Ordering from Chicago
When do teams in Chicago need warmup gear?
Hoodies and quarter-zips are needed from October to April, when Chicago's average high is under 65°F, so have them on hand before October; the coldest weeks inside that stretch call for insulated jackets and beanies on top.
