Review on Ultimate Fit: Adjustable Workout Sports Face Mask for Women and Men - Boost Gym Performance & Breathability by Matthew Watkins

The masks are comfortable and well made. The slider to adjust the tension of the ears is a good idea. However, the masks are hot when you breathe into them. Air enters easily, but comes out badly. At the gym I tried folding the bottom of the mask which helped a bit. Since the masks consist of two layers of material, I tried to cut out one layer. It made breathing easier, but the breath out was still too tight and too hot. This may be due to the synthetic material the mask is made of. Maybe cotton or a cotton blend would work better? Also, the colors shown on the male model's website are not true. What I got were MUCH lighter pastels which women are more likely to appreciate. Maybe I'll try coloring them?
