The site is already baking by nine and the cooling fan vest pushes a steady stream of air up your back.

This is a men's summer fan vest with small electric fans set into the lower back. You clip a power bank into the inner pocket, run the short cable to the fans, and they draw outside air in and send it up across your torso, so the shirt underneath stops clinging in the heat.

The shell is a lightweight nylon with a smooth polyester lining, cut loose so it layers over a t-shirt without pulling at the shoulders. A full front zip runs to a stand collar, there is a flap chest pocket and lower pockets for a phone and small tools, and the high-visibility orange and green options add silver reflective strips across the chest, back and shoulders for low light.

Key Benefits

• Built-in back fans Two or four fans, depending on the option, move air up through the vest to cool your torso on hot days.
• USB power bank driven A 5V or 12V fan system runs from a power bank through the included cable, with a USB charging lead in the box.
• High-visibility options The fluorescent orange and green versions carry silver reflective strips for road, warehouse and night shift work.
• Loose work fit The vest cut leaves your arms free and layers easily over a shirt, with a full zip and stand collar.
• Handy pockets A flap chest pocket and lower pockets hold a phone, keys and small tools while you move.
• Sizes S to 4XL Seven sizes mapped to height and weight cover a broad range of builds.

Best for: outdoor workers, delivery riders, warehouse staff and anyone who spends summer days on their feet in the heat.

Why It Works

Instead of trapping sweat, the fans keep a constant flow of air between the lining and your shirt, so heat and damp move out rather than sitting against your skin. The nylon shell is thin and quick to dry, and the loose vest shape gives the moving air room to travel from the lower back up to the collar.

Quick Product Facts: Shell: lightweight nylon; Lining: polyester; Fans: two fan or four fan back system; Power: 5V or 12V from a USB power bank; Colors: fluorescent orange, green and plain gray, blue, white and beige; Sizes: S to 4XL; Battery: included only on the accessory set options.

How It Fits Your Routine

Charge the power bank overnight, drop it into the inner pocket in the morning and switch the fans on before you step outside. On a long shift the airflow keeps the middle of your back from soaking through by lunch.

On the road the fluorescent shell and reflective strips keep you seen at dusk, while the plain gray and blue options read as a normal vest for casual summer wear off the clock.

When the day ends, unclip the power bank and cable, then hand wash the shell and hang it to dry so the fabric keeps its light, airy feel.
