Smartwool Men's Hike Full Cushion Crew Socks
Lower PFAS concern. Natural fiber socks unlikely to need water-repellent coating. Smartwool's lack of disclosure leaves room for uncertainty.
Smartwool Hike socks are primarily merino wool with synthetic reinforcement, materials not inherently linked to PFAS use. Hiking socks typically don't need water-repellent finishes.
