A bag! Oversize, small, whichever is your choice you should consider that is going to suffer with water and sand, so bring one do not worry about suffering any damage
It is recommended that the material of the bag is made of natural fibers, if isn´t the case, choose a light color, and above all remember:
Fashions fade, style is eternal.
