- 2 valves improve airflow performance as you exhale. Great for any outside exercise in a polluted urban environment
- Filters hydrocarbons, diesel particulates, carbonaceous particulate material, pollen, allergenic dusts, and non-allergenic dusts
- Simple and unobtrusive design works well in hot or cold conditions
