Running in 2026 means people train more consistently, run longer, and sweat more. So the right fabric must focus on real comfort and moisture control.

Wearables & Apps → More data-driven training
Runners manage heart-rate zones, pace, and recovery—so they train more often.
Fabric focus: long-wear comfort + skin-friendly feel

• Prioritize: Moisture-wicking + Soft touch + Breathability
  
  

Run Clubs → More team/event shirts
Community running keeps growing. Team shirts must fit many body types and look good in photos.
Fabric focus: light, fast-drying, and suitable for printing

Zone 2 → Longer, easier endurance runs
Longer sessions increase the risk of chafing and moisture build-up.
Fabric focus: smooth hand-feel and airflow for long comfort

• Prioritize: Soft/low friction + Breathability + Comfort
  
  

Treadmill/Indoor running → Heavier sweat, more humidity
Indoor runs often feel hotter and sweat accumulates faster.
Fabric focus: maximum ventilation + fast dry performance

2) The 5 “must-have” features of polyester running fabric

When selecting polyester sports fabric for running in 2026, use these five checkpoints:

1. Moisture-wicking
   Moves sweat away from the skin to reduce stickiness and discomfort.
   
   

2. Quick-dry
   Essential in hot/humid climates and for frequent training.
   
   

3. Breathability
   Helps prevent overheating—especially for indoor runs or warm weather.
   
   

4. Lightweight feel
   Improves comfort and reduces drag during movement.
   
   

5. Soft / Low-friction surface
   Critical for longer runs to help reduce irritation and chafing.
   
   

Tip: Don’t rely only on labels like “dry-fit.” Evaluate the knit structure + GSM (fabric weight) + finishing together.

3) Choose the right fabric structure (most important when buying in rolls)

A) Single Jersey (Polyester Jersey)

• Best for: everyday running tees, training tops, event shirts
  
  

• Key benefits: lightweight, comfortable, easy to produce, fits broad markets
  
  

• Recommend when: you want a “core fabric” that works across many products
  
  

B) Mesh / Micro-mesh

• Best for: hot-weather running tops, indoor training, ventilation panels
  
  

• Key benefits: excellent airflow, reduces heat and humidity build-up
  
  

• Recommend when: the customer’s #1 requirement is “cool and breathable”
  
  

C) Interlock / Double knit

• Best for: premium running/activewear tops, styles needing a cleaner look and better structure
  
  

• Key benefits: smoother face, more stable hand-feel, better shape retention, premium appearance
  
  

• Recommend when: you need a more “structured, elevated” product feel
