NFL teams have had the luxury of trying out new looks on the gridiron ever since the league began to loosen its uniform design policies over the last decade.
The NFL expanded its uniform policy in 2018, allowing for more jersey options for each club, but the limit of one helmet per team due to safety concerns kept classic threads like the Philadelphia Eagles' kelly green uniforms on the sidelines due to clashing colors between the jersey and helmet. In 2022, the NFL finally approved teams wearing two different helmet designs, and that number will be boosted to three beginning in 2025.
