Heat waves, intense physical exertion, work clothes... When the heat becomes a real obstacle, a cooling vest is the solution to help you stay on top, even under pressure. This guide explains how it works, its concrete benefits, and how to choose the model that suits your lifestyle. Discover the G-Heat vests, designed to keep you cool whether you're an athlete, a professional, or an everyday adventurer.
Why wear a cooling vest?
Your ally against the heat
Summer is merciless! Whether you're working on a construction site, running a half marathon, or suffering from urban heat, your body is under a lot of thermal stress. Sweating profusely, fatigue setting in, risk of heat stroke... Overheating spares no one. That's where the cooling vest comes in: it helps you better manage rising temperatures and offers a real burst of coolness without hindering your movements. At G-Heat, we consider this garment essential for anyone who experiences heat up close.
Fatigue, decreased performance, or hyperthermia: how does it help you?
A cooling vest is much more than just a way to feel less hot. It allows you to last longer, keep a clear head, and limit fatigue. As soon as your body temperature exceeds 101°F, you are at risk of hyperthermia: slowed circulation, reduced alertness, and possible discomfort. Whether you are exercising or working on a construction site, these risks are serious. The vest acts as a support for your thermoregulation, dissipating heat, relieving your heart and boosting your overall performance. Studies show that targeted cooling can lower your heart rate and delay fatigue when it gets really hot. In short, it's not just an accessory, it's a real partner in crime.
How does a cooling vest work?
Cold packs that keep your temperature under control
Some vests use phase change materials (PCM): integrated modules that store cold. After 1 hour in the freezer, they release constant coolness for 2 to 3 hours. At G-Heat, we call this Phasecool. No moisture, no water dripping, just long-lasting coolness without discomfort. You put it on and, despite the heat, you stay focused on what matters.
A fabric that cools by capturing water
Other vests rely on an ultra-absorbent fabric made of polymer fibers. You soak it, wring it out, and it captures moisture and releases it as coolness through evaporation. This technology is called Polycool at G-Heat. More flexible, lighter, perfect for outdoor activities in the blazing sun. As a bonus, it offers UPF 50+ UV protection and manages perspiration with a breathable fabric.
How to choose the right cooling vest for you?
Phasecool or Polycool: which one is right for you?
It all depends on what you're looking for. If you want a stable, “dry” cooling effect under your work gear, go for Phasecool with its packs. Prefer to move freely with a lightweight, breathable fabric? The Polycool textile version is for you. Both can be activated at will and are designed to last. At G-Heat, we designed them to meet different but complementary needs.
Depending on your activity, here's what you need
Sports vest: freedom and breathability
When you're running, walking, or cycling, you don't want to be weighed down. You want a lightweight vest that cools you down and keeps up with you. Polycool models are perfect: flexible, effective for hours, ideal for running, trail running, or walks in the sun.
Work vest: protection under your professional gear
On a construction site or in a warehouse, the heat rises quickly. Is your gear already heavy? The Phasecool cold pack vest is your best ally. It slips easily under your outfit, without moisture or discomfort. Effective, simple, and reusable.
Everyday vest: comfort and practicality
Transport, city life, festivals... The lightweight textile vest is perfect. Easy to wear and quick to reactivate (just add a little water), it goes everywhere with you to keep you cool.
