Review (5/5): Excellent protection and fairly comfortable.
I use these gowns to work with pathogens and have found they offer superb protection. The thumbloops ensure the sleeves stay put and make glove changes much easier and safer. It works great to wear two pairs of gloves with the sleeves of the gown between the two. That way the outer pair of gloves can be changed easily, and the thumb loops keep the gown in place.
The material is completely impervious and is much tougher than simple plastic gowns, which tear easily. The material is also stiffer than plain plastic, which keeps it away from your skin and prevents you from getting clammy when the gown is worn a long time.
