How Should Ventilation Zones Be Designed for a Custom Running Jacket?

Update Time:2026/10/8

RUNNING JACKET VENTILATION

Place ventilation where heat builds up while preserving coverage and weather protection.

Ventilation zones for a custom running jacket should be positioned according to where heat and moisture are likely to build up during activity. Their location, size, and construction should support airflow without compromising the jacket’s required fit, coverage, or weather protection.

Evaluate placement

  • Upper and center back
  • Underarms
  • Side body panels
  • Upper chest where appropriate
  • Other high-heat zones identified during wear testing

Specify construction

  • Mesh panels, laser perforation, or more air-permeable fabric zones
  • Eyelets, punched openings, back vents, or layered vents
  • Location, dimensions, material, and opening size
  • Reinforcement, seam construction, and opacity
  • Relationship to surrounding panels

Balance airflow with protection and structure

More ventilation is not always better. Large openings or highly breathable panels may reduce wind resistance, coverage, structural stability, or weather protection. Review these trade-offs against the intended climate and performance requirements.

Test the jacket during running and repeated upper-body movement to check airflow, comfort, seam behavior, garment stability, and whether the vents remain effective after washing. At Call The STYLE, ventilation placement can be developed with the jacket pattern and fabric system before bulk production.
