The "air tunnel" design in the waist gathers helps expel moisture from the skin, keeping the back dry, even in areas prone to sweating. Made with breathable material, the diaper allows moisture to escape without letting urine seep in, ensuring the skin stays dry during active movement. The waist stretches 2.5 times softly for easy wear without constriction, fitting gently around the stomach. Its secure design supports the waist, prevents slipping, and effectively guards against leakage.
