Good Effort
A great mask that does what it says, but still too heavy for me. I found myself having heart palpitations after walking a ways while wearing this mask. It fit (for once, given my fat face), but was difficult to breathe through under duress. I found better in some of the thinner neck-gaiters of TV fame, but still keep this in my glove box as an emergency back up.
