A towel's absorbency is affected by three factors:
- The weight of the towel, known as GSM (grammes per square metre). A towel with a higher GSM absorbs more water than a towel with a lower GSM.
- The yarn that the towel is made with. A lower twist or zero twist yarn has a greater surface area and can absorb more water.
- The fibre used to make the towel. Top quality cotton, such as Supima, is very absorbent.
But no matter what towel you're using, the way you care for it will also affect its absorbency.
Never use fabric conditioner on your towel as this coats the fibres making them less absorbent and more "scratchy" over time.
