These towels by #isYoung are a nice generous size so suitable for body as well as face. You can tie them around your head like a bandana or drape around your neck as they're plenty large enough. There are two in a pack, one grey and one blue. They are really cold when wet, even in the heat (I don't know how it works but they cool down when flicked in the air, very clever!). Ideal for taking to the gym, sauna, beach etc. They are well made with no loose threads and I recommend them.
