What GSM Means — and Which One to Buy

GSM is grams per square metre: the weight of the fabric.

• 160–180 GSM: light and cool for summer.
• 200–220 GSM: the all-rounder that holds its shape.
• 240 GSM and up: thick, structured, made for oversized cuts.

In Dhaka heat, most people live in 180 and keep a heavyweight or two for winter.
