Absolutely nothing! Ok, not quite nothing, but they are all pretty similar!Our stripy range (so Cabana, Summer and seasonal designs) and the Essential towels are all made from the same material, 100 recycled and planet friendly!Our magic cooling towels are infused with jade stone to keep you cool for up to 6hrs (even through those sweaty workouts!).All of our terrific towels are sand-free, they are quick drying, super-absorbent, they won't hold on to any nasty odours and they pack down into a cute compact pouch for travel.All of these towels (not to mention the Hair Wraps and Ponchos) feel super soft and smooth against the skin, and no, they don't feel like the microfibre cloths you might have in your cleaning cupboard.
