While the appearance of the Outdoor Research Bugout Infinity Scarf might deceive you into thinking that this is any old scarf, the Bugout does more than just stylishly provide warmth. Injected deep into the soft, lightweight cotton of the scarf is Insect Shield® repellant, which is a proven formula designed to keep dangerous disease-carrying bugs at bay. Rather than applying a spray or lotion to your skin, this formula stays within the fabric of the scarf and won't lose its potency for at least 70 wash cycles.
