- Layer your clothing as recommended to avoid the risk of hypothermia.
- Getting winter clothing wet can significantly reduce its insulating properties.
- Rainwear:
- Maintaining waterproofness depends on the correct fastening of all elements (zippers, Velcro, buttons, protective strips).
- Mechanical damage, prolonged use or washing at high temperatures may reduce the level of water resistance.
- Intense physical activity can cause moisture to accumulate inside clothing, requiring the use of breathable clothing or intermediate layers.
- Thermal underwear:
- Does not provide protection against direct contact with chemical, thermal or mechanical factors.
- The effectiveness of moisture wicking depends on the proper fit to the body.
- Excessive stretching or damage to the material may reduce its performance properties.
- Maintenance and cleaning:
- Failure to follow washing, drying or storage instructions may result in loss of protective properties.
- The use of chemicals not recommended by the manufacturer (e.g. bleach, solvents) may permanently damage fabrics and protective elements.
- Clothing exchange:
- Clothing that is worn, frayed, mechanically damaged or has visibly deteriorated reflective elements should be replaced immediately.
- Regularly checking the condition of clothing is crucial to maintaining the user's safety.
