Safety Jackets: Materials and Insulation

safety jackets


When the weather gets cold, or if your workplace’s environment is natural cold (like an ice plant for instance), there is nothing more welcoming than thick and warm safety jackets. If you’re planning to buy some for your crew, here are two things to consider: materials and insulation.



Like other safety and protective workwear, safety jackets are manufactured using different materials or fabrics. The most common ones are listed below, along with some features worth noting.

  • Cotton Duck – This material is made of woven cotton fabric and is commonly used as an exterior for safety jackets. Many workers and businesses like this material because is it easy to clean. More importantly though, it is very durable and resistant to ripping and tearing.
  • Nylon – Nylon is another popular material for safety jackets. Like cotton duck, nylon is pretty easy to clean. Workwear made of this material are also lightweight, which is one reason why this is preferred by many workers. They are also resistant to water and wind, which is a big plus. The only thing you’ll need to worry about is that “swishing” sound it makes when the fabric rubs against itself, which usually happens in the armpit areas as you swing or move your hands.
  • Polyester – There are also safety jackets that are made from polyester. Among all the different materials mentioned, this one is the most difficult to clean. However, they are very lightweight. This makes them perfect for workers who don’t need a high level of protection and wants something comfortable.



Safety jackets can have insulation embedded in them. This is especially true for those jackets which are intended to be worn at night or in cold workplaces. There are different types of insulation used, but the two most common are the following.

  • Down – This is considered to be the most efficient type of insulation for safety jackets. This is because of its capability of trapping air which is referred to as “fill power”. The higher the fill power of the down, the better it is at trapping air. Keep in mind though that this does not refer to how warm the jacket it. However, safety jackets with down insulation is not recommended in wet workplaces. This is because down loses its function when it becomes wet.
  • Synthetic or Polyester – This type of insulation is bulkier or “fluffier” than down. However, it is not as efficient when it comes to trapping air. Still, there are several reasons why this type of insulation makes for a better choice. First, safety jackets with this insulation are often less expensive that those that use down. Second, and perhaps the most important reason, is that this type of insulation works well even when it is wet. If your workplace is usually wet and cold like an ice plant or fishing vessel, then these make excellent choices.
