High Exposure Risk — Why This Product Category Matters

Underwear is in direct, prolonged contact with some of the body's most sensitive and absorptive skin. Synthetic fabrics release microplastics and phthalates through dermal absorption. For children, whose skin is thinner and more permeable, this exposure is particularly concerning during critical developmental years.
