What is GSM and Why Does it Matter?

What is GSM?

GSM stands for grams per square metre, which refers to the weight of a fabric. In general, the higher a fabric’s GSM, the thicker and more hard-wearing it’s likely to be. For example, denim has a much higher GSM than chiffon.


GSM is an important consideration when it comes to choosing clothes for specific sports or activities. It helps to regulate body temperature and maximise your performance.  We use merino wool through-out our clothing range, the multi-climate abilities, breathability, moisture absorption and odour reduction makes it perfect for the task.  Combined with Nuyarn technology, the patented twist free process amplifies these properties and vastly improves performance.  Our guide will help you understand GSM and choose the best GSM for your chosen adventure.
