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.
Why We Rated It This Way
Gap's cotton-spandex blend adds elastane (a synthetic polymer) to the mix. While the cotton content is better than full synthetic, the lack of organic certification and PFAS testing data is a gap in their safety story.
