Flag up. Whistle on. The ball is out, and the field knows.
The flag set every soccer assistant referee runs the touchline with. High-visibility checker patterns, balanced poles, and the corner-flag sets every association field needs.
- Yellow-orange checker AR flag sets for the linesman calling offside.
- Red-yellow diamond head linesman sets for the lead crew chief.
- Spike-base corner flag sets with spring action for full field setup.
The flag is the line. Wave it like one.
