The material also tends to be more absorbent and fast dry. Another quality that DrichillTechnologyhas to offer is that it can be super stretchy to fit any size so that your hair is breathable. This version also has an improved lightweight feature than before to take advantage of the body’s natural cooling mechanism for maximum comfort.
