Understanding 100% Polyester: GSM & Fabric Types Explained (Ultimate Guide)

100% Polyester Dri-Fit Fabric Guide: GSM & Fabric Types Explained (Singapore & Malaysia)

Polyester dri-fit fabrics are widely used for sportswear, corporate activewear, and outdoor events in Singapore and Malaysia due to their moisture-wicking, quick-dry, and durable properties. This guide explains GSM and the main polyester fabric types to help you choose the right material for your application.

Quick answer: For hot and humid climates like Singapore and Malaysia, 130–150 GSM eyelet or mini-eyelet polyester offers the best breathability for sports, while 150–170 GSM interlock polyester provides a cleaner, more professional look for corporate dri-fit T-shirts and sublimation jerseys.

Understanding GSM in Polyester Dri-Fit Fabric

GSM = Fabric Weight

Polyester dri-fit fabrics typically range from 130 to 180+ GSM. Lower GSM fabrics feel lighter and cooler, making them suitable for sports and outdoor use, while higher GSM fabrics feel more structured and professional.

• 130–150 GSM: Lightweight sportswear, running events, marathons
• 150–170 GSM: Corporate dri-fit T-shirts and uniforms
• 170–180+ GSM: Premium polos and structured activewear

Choose polyester dri-fit when:

• You need quick-dry, moisture-wicking performance
• You expect frequent washing and long-term durability
• You want colourfast fabrics for outdoor use

Avoid or reconsider polyester if:

• You prefer the natural softness of cotton
• You plan to use DTG printing (polyester is not suitable)
