They feel sturdy yet remain pleasantly soft on the skin during use. Keep in mind that they do arrive with a very strong natural grass smell right out of the package. I highly recommend washing them in a water and vinegar solution, then letting them air or sun dry before your first use. Once the smell is gone, they are absolutely perfect!
