Activewear & Sportswear
Athletic clothing designed for exercise and sports. Often made from synthetic fabrics with moisture-wicking, odor-resistant, and stretch properties. May be treated with antimicrobials and PFAS.
Why It Matters
Worn during sweating when pores are open. Antimicrobial treatments often unnecessary. PFAS in water-resistant items. Synthetic fabrics shed microplastics when washed.
