Breathable Fabric: A Key to Comfort
Dec 17,2025
Breathable fabric is fundamental to modern apparel, especially activewear. Woven synthetic fabrics like polyester and nylon inherently offer limited air permeability due to their tight weave. However, true breathable fabric performance is less about the base fibre and more critically dependent on specialized finishing techniques.

For instance, common woven fabrics like Pongee, Taslan, and four-way stretch woven materials are often inherently dense. Their status as a high-performance breathable fabric is primarily achieved through advanced back-end processes like micro-porous membranes or coatings. These technologies allow water vapour (sweat) to escape while blocking external moisture. In outdoor jackets, this creates a breathable fabric system that ensures physical exertion doesn't lead to a clammy, stifling feel, maintaining dry comfort.
The quality of a breathable fabric is quantifiable. Key methods measure Moisture Vapour Transmission Rate (MVTR) or Ret (Evaporative Resistance). Standards like ISO 11092 (Rating: lower Ret value = better breathability) and ASTM E96 (Units: g/m²/24h; higher value = better breathability) provide benchmarks. AATCC 195 also assesses liquid moisture management. These tests prove that a genuine breathable fabric isn't accidental but a verified engineered feature, with optimal values directly correlating to enhanced wearer comfort. Ultimately, selecting a verified breathable fabric is crucial for superior functionality.
