• System 3 layers

When doing sports, your body generates a lot of heat from the energy you expend. As you know, physical activities are accompanied by sweating. If you do not wear functional clothing, sweat remains on your skin and in the first layer, which becomes damp. As a result, it is more difficult for your body to regulate heat and you can become overheated or hypothermic.

Functional clothing wicks sweat away from the skin, so your body remains dry and ready to maintain the ideal working temperature. PROGRESS functional clothing respects the principle of three layers, which create the perfect bodily microclimate, enabling optimal performance. Each layer has its own unique and important role and together they form an ingenious string of functions. The most important thing is to know how to compose the functional items of clothing so that they best suit your individual requirements, intended activity and weather conditions.


The base layer is essential. It efficiently wicks the sweat from the skin to its outer side, from where the sweat evaporates into the air or into the next layer. The base layer should closely fit to the body and be used in all activities.


The mid layer thermally insulates your body and transfers sweat into the air or into another layer. In cold weather, this layer provides the optimal thermal comfort to suit your individual needs. If there is no need for thermal insulation, this layer can be omitted.


The third, shell layer is your protection against the elements. It enables high performance regardless of the weather and ensures that you stay comfortable. It is the shell layer that plays the most demanding role: it protects you from the cold, rain and wind and at the same time draws sweat and excessive heat away from the lower layers. This layer is optional, depending on the weather conditions.

How to dress properly

  • Layers are always a good idea. Two t-shirts keep you warmer than one thicker T-shirt, and in an emergency you can share one with somebody.
  • Try to combine your layers so that all of them really can draw moisture as far from the body as possible.
  • If you can’t give up cotton, it’s better to put on a functional t-shirt and a cotton sweatshirt than a cotton t-shirt and a functional sweatshirt! A sweatshirt will get soaked, but a functional t-shirt will always insulate you from moisture (i.e. cold, too). 
  • If you’re heading out for some short but strenuous activity in cold weather, dress so that you’ll feel cooler rather than warmer as you leave the warmth of your home. When you get yourself warmed up to "working temperature", you’ll feel good and will not sweat too much.
  • A spare t-shirt, socks and perhaps a cap in a pocket of your backpack might add a bit of weight, but they could help save you or your colleagues.
  • Backpack straps and Velcro could damage your clothing (if this happens, it could result in a claim being rejected – see our Complaints Procedure).
