FAQs
Will a cooling vest fit under my work gear?
It depends on the vest, and it's the question that decides whether you'll actually use it. If you wear hi-vis, a harness, welding leathers or riding gear, a bulky vest is a vest that stays in the truck. Low-profile phase change vests are usually the right answer under PPE — they're thin, they don't need water, and they cool regardless of what's over them. Check the profile before you buy.
Which cooling vest is best for outdoor work?
It comes down to humidity. In dry heat, an evaporative vest is cheap and highly effective — soak it, wear it, it cools as it dries. In humid heat, that same vest barely works, because the air is already saturated. For humid conditions, or for wearing under other gear, phase change is the answer. For a full shift in relentless heat, phase change with spare packs or a circulatory system.
What is a cooling vest and how does it work?
A cooling vest is a specialized piece of wearable gear designed to help regulate your core body temperature in high-heat environments. Unlike standard clothing, these cooling vests use advanced cooling technologies such as frozen ice packs, phase-change materials (PCMs), or evaporative fabrics to draw heat away from the body.
By keeping your torso cool, cooling vests help reduce the physiological strain on your heart and lungs, allowing you to remain active and focused in high temperatures.
The primary safety benefit of a cooling vest is the prevention of heat-related illnesses, such as heat exhaustion and heat stroke. By stabilizing the core temperature, these vests mitigate "brain fog" and physical fatigue, which significantly reduces the risk of workplace accidents and errors. Beyond safety, they provide a massive boost to daily comfort; for individuals with heat-sensitive conditions like Multiple Sclerosis or for those working in humid warehouses, a cooling vest can be the difference between staying productive all day or having to retreat indoors to recover.

What are the different types of cooling vests and their benefits?
There are four primary categories of cooling vests, each offering unique benefits for safety and daily comfort depending on your environment.
Evaporative cooling vests are the lightest and most affordable option, using a special water-activated fabric that provides a steady cooling effect as moisture evaporates in dry, breezy conditions.
For those who need more aggressive relief, ice vests use frozen water inserts to deliver an intense "refrigerated" chill, perfect for quick recovery or high-heat tasks.
Phase change material (PCM) vests are a professional-grade choice that maintain a constant temperature and no condensation, making them the best option to wear under heavy PPE or body armor.
Finally, circulatory cooling vests, also known as liquid-cooled or pumped-water vests, represent the most advanced technology by using a battery-operated pump to circulate chilled water through integrated tubing. These provide the most consistent and long-lasting cooling regardless of the outside humidity or airflow, making them the gold standard for pilots, race car drivers, and industrial workers in extreme conditions.

What is a Phase Change Materiel Vest (PCM)?
A Phase Change Vest (often called a PCM vest) is a specialized type of cooling garment designed to maintain a constant, comfortable body temperature in high-heat environments.
PCM Vests utilize Phase Change Materials, which are engineered liquids (usually bio-based oils or salts) that are designed to solidify and melt at a specific temperature, most commonly 58°F (14°C).
How It Works:
The "Phase Change" refers to the material moving from a solid to a liquid state.
Heat Absorption: As your body heat rises, the solid cooling inserts absorb that thermal energy.
Constant Temperature: During this melting process, the material remains at its designated temperature (e.g., 58°F) until it has completely melted.

How exactly does a circulatory cooling vest system lower my temperature?
A circulatory cooling vest works like a wearable radiator for your body. The system consists of a vest lined with flexible micro-tubing, a water pump, and a reservoir (typically an ice-filled bladder or cooler). The pump circulates ice-cold water through the tubes, which absorb your body heat as the water passes over your chest and back. This warmed water then returns to the reservoir to be re-chilled, creating a continuous cycle of active cooling that can significantly lower your perceived temperature compared to passive cooling methods.
How do motorcycle cooling vests work under riding leathers?
When choosing a motorcycle cooling vest, the best option depends on whether your jacket is mesh or solid leather. Evaporative vests are the most common and affordable; they are soaked in water and use airflow to pull heat away, making them perfect for mesh jackets but less effective under non-vented leathers. For riders in heavy leathers or those in high-humidity areas, Phase Change Material (PCM) vests are the preferred choice because they use solid inserts that remain at a constant 58°F without requiring airflow or producing dampness.
For the most extreme heat or long-distance touring, circulatory cooling vests deliver the highest performance. These systems use a battery-powered pump to circulate ice-cold water through a network of micro-tubing sewn into the vest, providing active, "refrigerated" cooling regardless of the outside temperature. While ice vests provide a similar aggressive chill using frozen packs, they are typically bulkier and better suited for shorter rides or track-day breaks rather than all-day touring.
