GSM (grams per square metre) determines how a coverall balances durability against breathability. Here's how to pick the right range.
What GSM Actually Measures
GSM (grams per square metre) measures fabric density and weight. Higher GSM generally means more durable, heavier fabric; lower GSM means lighter, more breathable fabric — the right choice depends on climate and the mechanical wear the coverall will face.
Common GSM Ranges for Industrial Coveralls
- 180–220 GSM: lighter, more breathable — suited to hot climates and lower mechanical wear tasks.
- 240–260 GSM: a practical middle ground for most factory and workshop use — this is the range used in our Premium Industrial Cotton Coverall.
- 270 GSM and above: heavier, more durable — better suited to abrasive or high-wear environments, at some cost to breathability.
Matching GSM to Your Climate and Task
In hot, humid conditions common across Tamil Nadu's industrial belt, the 240–260 GSM range tends to balance comfort and durability well for a full shift — see our dedicated guide on choosing coveralls for hot and humid environments for more detail. Heavier fabric earns its keep on tasks with more mechanical abrasion, at the cost of some breathability.
Frequently Asked Questions
What GSM is best for hot, humid climates?
A 240–260 GSM 100% cotton twill typically balances breathability and durability well in hot, humid conditions — heavier fabric trades some comfort for extra durability.
Does higher GSM always mean better quality?
Not necessarily — higher GSM means heavier, more durable fabric, but if the task doesn't involve heavy mechanical wear, a lighter GSM coverall can be the more comfortable and practical choice.
