About the Fabric GSM Our products are 90 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.
