These blends balance comfort, stretch, and durability.
Why Cotton Is Less Ideal for High-Performance Sportswear
While cotton is soft and breathable, it has limitations.
Cotton absorbs moisture and holds sweat against the skin, which can lead to discomfort, reduced cooling, and prolonged drying times during exercise. Pure cotton is better suited for casual wear or low-intensity activity.
Blending cotton with synthetic fibers can help mitigate these issues.
Benefits of Cotton in Blends
- Soft hand feel
- Skin comfort
- Natural fiber appeal
- Suitable for low-intensity activity
Limitations of Pure Cotton
- Retains sweat
- Slower drying
