Merrell · Waterproof Hiking Socks
Merrell Premium Wool Trail Crew Socks
Lower PFAS risk, wool socks without disclosed treatments carry minimal concern.
Premium wool naturally sheds water and resists odor without chemical help. Merrell makes no PFAS claims and discloses no water-repellent coating or stain treatment, suggesting minimal chemical processing.
