The portable sauna is the new way of camping. Modern camping saunas are made of a special waterproof and fire-resistant Oxford material, which holds all the steam inside. The temperature inside the portable sauna can reach up to 110 C (230 F). Thanks to the special construction of the furnace, you cannot burn the tent –the spark-arrester doesn't let sparks fly out of the chimney. It is also used with portable stove to warm it up fast. Furthermore, it is made of stainless steel and equipped with spark arrester for comfortable and safe use.
