This beautifull Bohemian style Zara rug by Salty Aura is made of cotton, making them durable and long-lasting. They are soft and non-irritant with good air permeability, keeping the wind off your skin on those cold nights. The tightly woven material also allows it to be used as a picnic rug, shielding you from the sand, grass or prickles. We would describe them as being as thick as a towel.
