Okay, but some issues [SEP] Liked them because I was able to breath a bit better. A little more air flow. Felt some what cooler.<br /><br />Disliked the bridge of the nose gets sore for all day use. Also they move around in the mask, I had to sew it to the fabric mask but now have to hand wash.<br /><br />I would recommend for excerizing but not all day at work.
