What is GSM?

GSM stands for grams per square meter (g/m2). Material with a higher GSM weighs more than material with a lower GSM. It is typically thicker, and if there is a pile, it is more plush. Heavier towels will absorb more liquid than lighter towels.

Most general use microfiber is between 200-350 GSM. Since the lower weights have a lower pile, they are are less likely to streak or lint on glass, and are a bit more aggressive. Heavier weights are more durable, and have a more gentle cleaning action. 300GSM is the most popular weight for microfiber towels.

Towels 360GSM and over and typically used for surfaces that need to be treated with extra care (automotive finishes, musical instruments). The higher pile pulls debris away from the surface where it is less likely to scratch the during the wiping process.
