Why cooling vests make sense in summer

When temperatures rise, concentration, comfort and physical resilience can quickly come under pressure. Cooling vests help reduce heat exposure and make the working day more manageable. They are especially useful wherever workers are exposed to direct sunlight, warm ambient air or physically demanding tasks.

  • support a more comfortable body feeling in hot conditions
  • can reduce temperature-related fatigue during work
  • are lightweight, mobile and quickly ready for use
  • are suitable for changing work locations and long working days

How the cooling technology works

Evaporative cooling with Cooling 360° technology

Cooling vests use a cooling fabric technology that stores water and creates a pleasant cooling effect through evaporation. The system is simple, quick to reactivate and especially practical for everyday professional use.

  • cooling fabric with absorbing, cooling and drying properties
  • helps keep heat away from the body
  • can help slow down an increase in core temperature
  • lightweight feel without bulky cooling packs

Use in 3 simple steps

Instructions for using a cooling vest in three steps

Quick to prepare, quickly ready for use

  • Step 1: Soak the vest in cold water for 1–2 minutes.
  • Step 2: Carefully wring out excess water.
  • Step 3: Put on the cooling vest and benefit from long-lasting cooling.

Once the vest starts to dry out, it can simply be wetted again and reactivated. This makes it especially easy to use — even on construction sites or while on the move.
