Description
Heat Is Not Discomfort. It Is the Enemy of Performance. The body at 38°C is not the same body that operated at 22°C — reaction time slows, decision quality degrades, and the line between endurance and exhaustion blurs into a single throb of discomfort. The Halo Draft does not promise to make summer feel like autumn. It promises something more honest: that your body will operate at its intended temperature regardless of what the sun is doing.
Two 5V brushless fans, positioned at the lower back and integrated into a ventilated hood, pull ambient air through mesh channels sewn directly into the vest's lining. The airflow is not a gimmicky breeze — it is a continuous, laminar curtain that displaces the micro-climate of sweat and heat your body generates inside any enclosed garment. The hood channels exhaust heat upward from the neck and scalp, where the body loses 40% of its thermal load. Powered by any standard USB power bank (not included), the system runs for 6–8 hours on a 10,000mAh pack at medium speed.
The vest itself is cut from ripstop polyester with a DWR (durable water repellent) finish — light enough to wear over a t-shirt, structured enough to hold its shape under a backpack. It is not a fashion statement. It is a thermal management tool that happens to look like outerwear. For construction crews working August asphalt, festival-goers enduring 10-hour sun exposure, motorcyclists trapped in traffic at 35°C, and warehouse workers whose shift starts at 2 PM and ends when the thermometer finally relents — the Halo Draft is a productivity multiplier disguised as clothing.
The sun does not negotiate. The Halo Draft does not need it to.

Application Scenarios
The Halo Draft serves anyone whose work or recreation demands sustained physical presence in high-heat environments. Construction workers laying asphalt and framing roofs in direct July sun. Warehouse and logistics personnel moving through un-air-conditioned distribution centers. Motorcyclists and ATV riders whose protective gear creates a personal greenhouse at every red light. Outdoor festival and event staff working 12-hour shifts in open fields. Fishermen and boat crew dealing with reflected UV off open water. Hikers and trail runners who need variable cooling without stopping to change layers. The hooded design distinguishes the Halo Draft from standard cooling vests by addressing neck and scalp heat — the thermal exhaust port that conventional vests ignore.
Frequently Asked Questions
Q: What power bank do you recommend?
A: Any USB-A power bank with 5V/2A output works. A 10,000mAh bank gives 6–8 hours on medium speed and fits in the vest's internal cable-routing pocket. Anker, RAVPower, and Xiaomi power banks have been tested and confirmed compatible. The vest does not include a power bank.
Q: Can I wear a backpack over the vest?
A: Yes, but be mindful of the lower-back fan intake. A backpack with a ventilated back panel (trampoline-style suspension) works best. A pack pressed flat against the fan intake will reduce airflow by approximately 40%. The hood fan is unaffected by backpack use.
Q: Is it rainproof?
A: The shell has a DWR coating that sheds light rain and mist. The fan units are not waterproof — do not submerge or use in heavy downpour. If you are caught in rain, remove the fans from their mesh pockets (5 seconds each) and stow them. The vest itself will dry quickly.
Q: How much cooling does it actually provide?
A: The Halo Draft reduces perceived skin temperature by approximately 4–7°C in 35°C ambient conditions, measured via thermal imaging at the back and neck contact points. It is not air conditioning — it is forced convection that accelerates your body's natural evaporative cooling. In still air, the effect is dramatic. In windy conditions, the fans supplement natural airflow through clothing layers.
Q: Can I use it with a 12V USB adapter in my car?
A: Yes. Any 12V-to-USB adapter with 5V/2A output works. This is ideal for drivers and passengers on long summer road trips, particularly in vehicles without air-conditioned seats.
Q: How do I clean the vest?
A: Remove both fan units from their mesh pockets. Hand-wash the vest in cold water with mild detergent. Hang to air-dry — do not machine-dry, as heat can damage the DWR coating and mesh. The fans can be wiped with a dry cloth. Store with fans removed to prevent compression damage to fan blades.
