Once you have decided on the ideal towel size for your business or
customer's needs, the next thing to consider is GSM. GSM stands for
grams per square meter and towels typically range from 300 to 900
GSM. Beach towels tend to have a lower GSM because they need to be
compact, lightweight and quick drying, while bath towels tend to
have a higher GSM. The higher the GSM, the more absorbent and
luxurious the towel will be. Also, there is nothing better than
having a nice thick, heavy towel with a higher GSM to lay on when
sunbathing, to cushion any lumps or bumps and keep you dry and
comfortable as you relax.
