Frequently Asked Questions


What does GSM mean?

GSM (Grams per Square Metre) measures the weight and thickness of fabric. A higher GSM means a thicker and warmer fabric, while a lower GSM is lighter and more breathable.

What GSM are MTH Loyalty T-shirts?

Our t-shirts are 180 GSM, offering the perfect balance of durability, comfort, and breathability.

What GSM are MTH Loyalty Hoodies and Sweatshirts?

Our hoodies and sweatshirts range from 280-350 GSM, ensuring warmth, durability, and a premium feel.

Which GSM is best for different weather conditions?

  • 180 GSM (T-shirts) - Lightweight and breathable, perfect for all seasons.

  • 280-350 GSM (Hoodies & Sweatshirts) - Heavier and warmer, ideal for colder weather and layering.


Why 180 GSM for T-shirts?

  • Perfect balance - 180 GSM is a mid-weight fabric, making it breathable but not too thin.

What is the difference between shell-single jersey and shell- brushed?

  • Shell-single jersey: A smooth, lightweight knit fabric commonly used in t-shirts. This has a soft texture, good stretch, and breathability, making it ideal for everyday wear.

  • Brushed Fabric: A thicker, warmer fabric where the inner surface is brushed to create a soft, fleece-like texture. It is commonly used in hoodies, sweatshirts and joggers, for added warmth and comfort.
