@josepilove The solution I've found is to wear a lightweight, synthetic neckie while riding, and pull it up when passing or interacting with others. Personally, I find typical masks very restrictive of my airflow, so I opted for something made of more breathable material. 

I reccomend taking a peek at these neckies from one of my favorite ultimate frisbee brands: https://ca.vcultimate.com/collections/neckies. They sit comfortably around my neck to offer lightweight sun protection and it's easy enough to pull it up over my face when needed. Hope this helps!
