The fabric is skin-friendly breathable eco-friendly & very silky) with carbonated hot spring water moisturizes & revitalize your skin as if you just soaked yourself in natural hot spring water. That means your skin will feel refreshed & reinvigorated immediately after coming out from spa almost like you've pressed a reset button on it!
