The material is great, it definitely stays cooler on my face than other buffs I use. My issue is that it isn't long enough. Before and (eventually) after the pandemic, I use these as sun protection on long hikes above treeline. This is too short to simultaneously pull up over the back of my head and under a hat while also covering the entire back of my neck. So close...
Great and easy to breath
Other than someone mistaking the cute bears as Kansas JayHawks, this mask has been great for trail and town.
The item is a very breathable face mask. The only problem is that I have to pull it up very high for it to stay over my nose and it gets a little uncomfortable. The fabric is much cooler and allows for better ventilation than other clothes masks, though.
