When the heat builds up, your body works hard to stay cool, and that effort drains your energy fast. The BERTSCHAT® cooling vest range uses PCM (phase change material) elements that absorb excess body heat and hold a stable temperature for hours. No batteries, no water, no noise. Just steady cooling for hot days and active use.
PCM cooling for warm days and active use
The collection is built around the cooling vest with PCM elements, designed to sit close to the body and draw heat away where it builds up fastest. The elements absorb excess body heat and release it gradually, so you get a consistent cooling effect rather than a short cold shock.
Once the elements have absorbed their maximum, you recharge them and use them again. Keeping a spare set of PCM cooling elements on hand means a fresh set is ready the moment the first one warms through. That makes the vest practical for long shifts, warm commutes or a full day outdoors.
The cooling vest sits alongside the rest of our cooling range, which covers different situations where temperature gets in the way of comfort.
What to look for when choosing a cooling vest
- Cooling method: PCM elements give you passive cooling without batteries or a power source, which suits long stretches away from a plug. Evaporation cooling, used in our hats, works differently and needs water to activate.
- Fit: A cooling vest works best when it sits close to the body, so the elements make direct contact where heat builds up. Check the size guidance before ordering.
- Cooling duration: How long the elements stay cool depends on the surrounding temperature and your activity level. A spare set of elements extends your comfort across a full day.
- Use case: Think about where you will wear it, whether that is a warm commute, physical work, sport or a heatwave at home. This shapes how many elements and spares you need.
- Reusability: PCM elements are reusable season after season. Once warmed through, you reset them and use them again, so your investment lasts well beyond a single summer.
