Breathability
Breathability is a fabric's ability to allow air and moisture vapour to pass through it, keeping the wearer cool and dry. It's the balance between insulation and ventilation.
Understanding the Term
How fabric manages heat and moisture.
Breathability has two components: air permeability (how easily air moves through the fabric) and moisture vapour transfer (how quickly sweat in vapour form passes through to evaporate on the outer surface).
Cotton is naturally breathable because its cellulose fibres absorb moisture. When you sweat, cotton fibres absorb up to 27% of their weight in water vapour, transporting it from your skin to the fabric's outer surface where it evaporates. This is passive wicking — no synthetic engineering required.
Fabric construction affects breathability significantly. Loosely knit fabrics are more breathable than tightly woven ones. Single jersey construction (with its open loop structure) provides excellent airflow. At 180 GSM, our fabric is dense enough for opacity and durability but open enough for year-round comfort.
Why It Matters
How breathability affects comfort.
The difference between comfortable and clammy.
01
Temperature Regulation
Breathable fabric helps maintain skin temperature by allowing excess heat to escape. This is critical in warm weather and during physical activity.
02
Moisture Management
Cotton's natural moisture absorption prevents that clammy, wet feeling that non-breathable synthetics create. The fabric works with your body's cooling system, not against it.
03
Odour Reduction
Breathable natural fibres reduce bacterial growth by keeping the skin surface drier. This means less odour development over a wearing session.
Our Standard
Cotton-native breathability.
We don't need moisture-wicking coatings or mesh panels. Supima cotton's natural cellulose structure absorbs and releases moisture vapour efficiently. Our single jersey construction provides open airflow channels. At 180 GSM, the fabric breathes well in Indian summers while providing enough insulation for air-conditioned offices.

Common Questions
Breathability — your questions, answered.
Understanding fabric comfort science.
For moisture comfort, yes. Cotton absorbs moisture vapour; polyester repels it. Polyester can wick liquid sweat faster, but for everyday comfort (not athletic performance), cotton's absorption creates a drier skin feel.
