This pair of Reima BugProof crew socks repels mosquitoes and ticks with a biodegradable lemongrass-based finish that uses geraniol. Made from 74% organic cotton blended with polypropylene, polyamide and elastane, these socks for kids are breathable, moisture-wicking and flexible for all-day comfort. Durable insect-repellent treatment stays effective for more than 50 washes and gives a mild lemon fragrance that is pleasant to people while deterring insects. This practical crew-length pair is ideal for outdoor play, hiking and camping, keeping feet comfortable and protected under clothing. Reinforced toes and an elastic cuff improve fit and wear-resistance for active children.
