What we think:
Tim can be seen wearing one of these gaiers daily. Not only does it provide sun and dust protection it works as a mask too! It's hard to forget when it's always around your neck!  
 
The technical stuff:
This neck gaiter is a versatile accessory that can be used as a face covering, headband, bandana, wristband, and neck warmer.
