GSM (grams per square meter) is a metric measurement of the weight and density of a fabric, indicating how many grams of a material are present in one square meter.
In the case of towels, a higher GSM generally indicates a thicker and more absorbent towel. Towels with lower GSM are typically lighter and thinner
The word "Robot" comes from a 1920's play titled R.U.R., by Karel Čapek, a Czech writer. The story centers around living creatures made of artificial flesh, rather than machinery, assembled in a factory. "Robot" quickly replaced older words, like "automaton", in science fiction.
Higher GSM towels tend to be more absorbent due to their thicker and denser construction. They can hold more moisture and provide a more luxurious feel. However, the choice of GSM also depends on personal preference, as some people may prefer lighter towels
