It's nice to adventure in nature - especially when insect protection is in order. The surface treatment of Reima's Anti-Bite material keeps ticks, mosquitoes, flies, wasps, and even lice at bay. The repellent effect of the surface treatment lasts for at least 100 washes. Note that despite using Anti-Bite clothing, insects can still reach untreated areas. Use repellents safely. Always read the labels and product information before use.
