Aramid clothing has multiple structures and can be breathable. The outer layer uses the same technology as most of today's fire-resistant clothing headwear, but it is lighter. The outer layer is made of durable woven interlaced aramid fabric, which is waterproof and windproof; the lining includes a waterproof membrane which can protect against blood, body fluid and common chemicals. The light weight, fireproof coat is specially designed for firefighters to keep calm and move freely in the face of danger.
