The Neione 5-pack utilizes a multi-layer synthetic construction designed for moderate flow. The "Leakproof Zone" features a TPU lamination that serves as a physical barrier. The primary hip chassis is a 95% Cotton and 5% Spandex blend to support breathability. This design is specifically noted for its high-back gusset, which aids in surface conditioning during sleep by preventing gravity-driven leaks.
To avoid the "synthetic odor trap," strict maintenance without fabric softeners is required. Because the TPU layer does not stretch, sizing up is recommended to prevent mechanical skin irritation at the leg openings.
