Lovely towels, super light weight and in a beautiful pink colour, will be great for travel (when travel is a thing again! ) The button ensures the hair towel stays on your head and does not slip. One criticism is that they absorbe water very well , which is obviously what you want, but as they are thin, even if you wringe your hair out before putting towel on, it stays very wet and struggles to dry rhe hair further as it holds water. Luckily I bought a double pack so I use one to initially take most of the excess water away from the hair. Then combe it through before wrapping in the dry 2nd towel to get the best performance. I can honestly say my hair blow dries better as more moisture is removed. Would recommend but buy the double pack if you have long or thick hair.
