This pair of Reima crew-length socks combines breathable, moisture-wicking comfort with stretchy elastic support for active kids. This Reima BugProof finish uses lemongrass extract containing geraniol to repel mosquitoes, ticks and other biting insects, remaining effective for more than 50 washes. This design is made from 74% organic cotton with polypropylene, polyamide and elastane for a soft, durable fit that moves with the foot. This breathable, flexible fabric has a mild lemon scent pleasant to people but disliked by insects, so outdoor play stays more comfortable. This product protects the skin covered by the socks; apply a suitable repellent to uncovered skin and follow repellent product instructions for safe use.
