There are three colors: Black and Gray hoods are for winter; Silver hoods having shiny fibers on the outer layer to reflect sunlight are preferred for summer.

The hoods have two styles:

1. Full-cover Hood forms air-pocket around nose and mouth and a tight fit around wearer’s eyes.
2. Open-face Hood gives the convenience of accommodating a full-face respirator. Its face opening is easy to pull down to cover just the mouth and chin, allowing the respirator direct contact with skin.
