The YoColorodo Face Masks are a good option for on-trail or around the town coverage from sun, dust and wind. It is not a medical mask, but works well on the trail when social distancing is difficult. I like the breathable mesh panel on the back of the mask to help one keep their "cool". This mask is not as long as other tube-like masks, which I like since wearing a turtle-neck should be saved for family photos in the dead of winters.
I have bought several of these over the last few months. I use buffs for running in general but these are light weight, have a nice stretch to them and perfect for summer months to leave around your neck just in case you need a mask somewhere. After a vaccine is hopefully found for COVID, I will use them for buffs as usually and headbands!
This face shield/gaiter has worked out during these strange times. Yo Colorado was awesome, they allowed me to pick up my order in person instead of waiting for it to be shipped.
