Listings show a range of fabric weights: lighter options around 400 GSM, midweight towels roughly 450–550 GSM, and heavier towels in the 550–800 GSM range (with specific 600 GSM mentions).
Care instructions commonly recommend machine washing and either tumble drying or line/lay-flat drying. Microfiber variants often add details: wash on low temperature and avoid bleach and fabric softeners.
