Running Apparel Fabric Guide: Moisture Management Explained

Running generates more sweat than almost any other activity, making fabric selection critical for comfort and performance. The wrong fabric creates a clammy, heavy, uncomfortable experience; the right fabric keeps runners dry, cool, and focused on their pace.

Critical Requirements for Running Fabrics

1. Moisture-Wicking (Essential)

What is Wicking?

Moving moisture away from skin to fabric surface
Allows rapid evaporation
Keeps skin dry during activity

How It Works:

Polyester fibers are hydrophobic (water-repelling)
Capillary action pulls moisture along fibers
Large surface area accelerates evaporation
Much faster than cotton absorption

Performance:

Quality wicking fabric evaporates sweat 3-4x faster than cotton
Skin stays drier throughout run
Reduces chafing and discomfort

2. Breathability (Airflow)

Why It Matters:

Running generates significant body heat
Trapped heat causes overheating
Good airflow regulates temperature

Fabric Construction:

Mesh fabrics: Maximum breathability (100-300 CFM)
Eyelet constructions: Enhanced air circulation
Lightweight jerseys: Good breathability (40-80 CFM)
Strategic ventilation: Mesh panels where needed most

3. Lightweight

Weight Recommendations:

Tops: 100-150gsm ideal
Shorts: 130-170gsm
Tights: 180-220gsm

Benefits:

Less weight to carry during run
Faster drying
Less restriction
Better in hot weather

4. Quick-Dry

Testing:

Spray fabric with water
Time until dry to touch
Target: 2-3 hours for running fabrics

Polyester Advantage:

Dries 2-3x faster than cotton
Doesn't hold moisture in fibers
Critical for multi-hour runs

5. Chafe Resistance

Causes of Chafing:

Wet fabric rubbing skin
Seams in high-friction areas
Stiff, abrasive fabrics

Fabric Solutions:

Smooth polyester surfaces
Flatlock seams
Soft hand feel
Moisture-wicking (keep skin dry)

Polyester: The Ideal Running Fiber

Why Polyester Dominates

Moisture Properties:

Hydrophobic (repels water)
Moisture regain: <0.4%
Wicks rather than absorbs

Drying Speed:

Critical for comfort

Durability:

Resistant to bacteria/mold
Color-fast
Shape retention
100+ wash cycles typical

Cost:

Addressing Odor Concerns

The Problem:

Polyester can retain odor-causing bacteria
Cotton naturally antimicrobial

Solutions:

Antimicrobial treatments: Silver ion most common
Wash promptly: Don't let sweaty garments sit
Vinegar rinse: 1/4 cup white vinegar in wash cycle
Proper drying: Bacteria grows in damp fabric

Warmer in sun
Fade over time (check color fastness)

Bright/Neon Colors

Advantages:

High visibility for safety
On-trend for running
Motivating aesthetic

Considerations:

Ensure color fastness (bright colors can fade)
AATCC Grade 4+ required

Testing Standards

AATCC Test Method 195 (Moisture Management)

What It Measures:

Wetting time (how fast moisture spreads)
Absorption rate
One-way transport (wicking from skin side to outer)
Drying rate

Interpretation:

Grade 1-5 scale
Grade 4+: Excellent moisture management
Grade 3: Acceptable
Below 3: Poor for running

Request from Suppliers:

Test reports for moisture management
Especially for premium/technical lines

Breathability (Air Permeability)

ASTM D737 Testing:

Measures cubic feet per minute (CFM)
Higher CFM = better breathability

Targets:

Slows moisture evaporation
Uncomfortable in heat

Mistake #3: Ignoring Breathability

Solid, tight fabrics trap heat
Overheating during runs
Mesh/ventilation essential

Mistake #4: Poor Color Fastness

Bright colors that fade quickly
Customer dissatisfaction
Specify AATCC Grade 4+
