Gerbing Cooling
Circulatory cooling vests that pump cold water across your core to lower your body temperature and keep you comfortable for hours.
How it works
Cooling that works with your circulation
Gerbing circulatory cooling vests use a built-in water circulation unit — a mini pump pushes cold water continuously through tubing embedded in a mesh liner. As that cool water flows across your core, it carries heat away from the areas where your blood runs closest to the surface.
Because you are cooling your core and the blood that circulates through it, the effect reaches your whole body — not just the spot the vest touches.

Why circulatory cooling
Cool the blood, cool the body
Your core and chest are where large volumes of blood move close to the skin. Continuously flowing cold water over that area lowers the temperature of the blood as it circulates — the same principle as pressing something cold to your chest on a hot day, engineered into a wearable vest you can move in.
The vest is designed to be worn close to the body, under an outer jacket or over a thin polyester base layer.
Two ways to stay cool
5V Touch Button vs 7V Circulatory
Gerbing makes two circulatory cooling vests. The 5V Touch Button vest is the compact, everyday option — one size, powered by a high-capacity 10,000mAh battery, and cooled with four refillable ice packs. The 7V Circulatory vest is the rider-focused system — available in four sizes, using a 2L ice-water bladder for a larger cold reservoir. Both circulate cold water for up to 8–9 hours of relief.
5V vs 7V
Compare the cooling vests
Both use the same circulatory cooling technology. The difference is the cold source, battery, sizing, and who each is built for.
Cooling — common questions
How does a Gerbing cooling vest actually cool you?
A mini pump circulates cold water continuously through tubing embedded in the vest's mesh liner. As the cold water flows across your core, it pulls heat away from your body and helps lower your core temperature — not just your skin.
What's the difference between the 5V and 7V cooling vests?
The 5V Touch Button vest is one-size, uses a 10,000mAh battery and four refillable ice packs, and is built for everyday cooling. The 7V Circulatory vest comes in four sizes, uses a 2L ice-water bladder and a 7V 2,200mAh battery, and is geared toward motorcycle riders who want a larger fit range. Both circulate cold water for up to 8–9 hours.
How long does the cooling last?
The rechargeable battery powers continuous water circulation for up to 8–9 hours. The cold itself comes from the ice packs (5V) or ice-water bladder (7V), which provide roughly 1–3 hours of cold per fill — refill or re-ice to keep going.
How do I refill or re-ice the vest?
The 5V vest uses four refillable ice packs you freeze and insert; the 7V vest uses a 2L bladder you fill with ice and water. Each provides about 1–3 hours of cooling before you refresh it.
How should I wear the cooling vest?
Wear it close to the body — under an outer jacket or over a thin polyester base layer. Both vests have a front zipper with adjustable sides for a snug fit that keeps the cooling tubes against your core.
Which vest should I choose?
Choose the 5V Touch Button vest for everyday cooling and simple ice-pack refills in a one-size fit. Choose the 7V Circulatory vest if you ride, want a larger cold reservoir (2L bladder), or need a specific size from XS/S up to 3XL/4XL.
