Active Cooling. Everywhere.
Some days the heat isn't a weather problem — it's a Tuesday problem.
The office runs the AC, but the conference room hits 90°F. The August commute swings twenty degrees between the parking garage and the lobby.
And passive cooling? It's just staying hot slower — an ice pack that melts, a wet towel that dries, shade you have to go find.
EarthBae Cool is the active alternative: thermal regulation vests that do real work to pull heat off your body — for hours, on demand.
Two mechanisms, one 7.4V battery.
EarthBae Air uses fan convection.
EarthBae Chill uses liquid conduction.
Wear them like any summer vest — through the overcooled office and the hot street alike — then switch them on when the heat turns real. Meet EarthBae Air and EarthBae Chill.
EARTHBAE COOLING
Active Cooling Vests
An active cooling vest uses a battery-powered mechanism to remove heat from the body — either fans that accelerate evaporative cooling, or circulated liquid that draws heat away through direct contact. EarthBae makes both, on one 7.4V battery, in a Sportif aesthetic built to look right wherever the day takes you.
What is an active cooling vest?
Active means it does work.
Passive means it just sits there.
An active cooling vest is wearable apparel that uses a battery-powered mechanism — fans or circulated liquid — to actively remove heat from the body. Active vests continue working for as long as the battery has charge.
The "active" half of the name is the part that matters. Passive cooling products — ice packs, cooling towels, phase-change inserts, evaporative-only vests — start cold and warm toward ambient temperature. They hold a fixed amount of cold. They fade.
Active cooling adds energy — a battery, a fan, a pump — and does continuous thermal work on the body. In a sustained heat exposure, the difference is not subtle. A wet bandana fades in twenty minutes. An ice pack fades in an hour. An active vest holds performance until the battery runs down.
Two mechanisms, one outcome.
EarthBae makes two active cooling vests because two different physical principles are needed for two different situations.
Fan convection (EarthBae Air) accelerates the body's natural evaporative cooling and shines in motion.
Liquid conduction (EarthBae Chill) pulls heat directly from the body through contact, and shines in sustained static heat. Most buyers need one — not both — and the choice depends on the day, not the price.
Heat moved indoors. Cooling apparel has to follow.
The buyers who need this are not always the ones who know the category exists yet. Six everyday situations where an active cooling vest earns its place — and which EarthBae product fits each.
Commuter
the august commute
Twenty-degree swing between the parking garage, the August sidewalk, and the air-conditioned building. A vest that turns on with the door and off at the desk.

Athlete & Active
The gym class with no AC
Hot studios, summer training sessions, athletic warm-down where the body is generating its own heat through movement. Convection earns its name here.
Pick: EarthBae Air
Outdoor & Trades — Active
The outdoor job site, active phase
Movement, sun, sweat. Fan-driven airflow accelerates evaporation across the back and shoulders where heat builds first. Lightweight enough to wear all day.
Pick: EarthBae Air
Industrial & Trades — Static
Welding, foundry, hot industrial
Sustained high heat. Limited movement. PPE that doesn't breathe. Liquid conduction continues to pull heat from the body regardless of humidity, sweat rate, or air circulation.
Pick: EarthBae Chill
Heat-Exposure Professionals
Operators in sustained high temperatures
The hour-after-hour static heat exposures where fan-based cooling reaches its limit. Conduction is the most thermodynamically efficient personal cooling mechanism available.
Pick: EarthBae Chill
Convection vs. Conduction
Two different ways heat moves out of the body. Two different products. One cooling problem each is built to solve.
Fan Convection Cooling
Convection moves heat away from the body by increasing the speed of air across the skin. Faster air carries away sweat vapor more quickly, which accelerates the evaporative cooling the body already does on its own.
- Mechanism — high-RPM fans circulate air across back and shoulders
- Best when — body is moving or active
- Lightweight, low-profile, high-mobility
- Humidity — most effective in low-to-moderate humidity
- Build — lightweight, low-profile, full mobility
Liquid Conduction Cooling
Conduction moves heat through direct contact between two surfaces of different temperature. Circulated cool liquid passes against the skin and carries heat away from the core continuously — without depending on air movement or evaporation.
- Mechanism — circulated liquid in tubes against the body
- Best when — sustained, static, high-heat exposure
- Humidity — performance is independent of humidity and airflow
- Build — technical fit for prolonged use
- Efficiency — the most thermodynamically efficient personal cooling mechanism available
Earthbae cooling PRODUCTS
Two cooling vests. One 7.4V ecosystem.
EarthBae makes two active cooling vests, each using a different mechanism to pull heat off your body. EarthBae Air uses fan convection. EarthBae Chill uses liquid conduction. Both run on the same 7.4V battery as EarthBae Core and EarthBae Heat — so one battery standard carries you from a January commute to an August jobsite.
EarthBae Air

Same Battery.
Every Season.
EarthBae Air and EarthBae Chill run on the same 7.4V battery as EarthBae Core (graphene heated hoodie) and EarthBae Heat (graphene heated vest). Same connector. Same charging protocol. Same battery.
This is not a product line — it is thermal regulation infrastructure. One purchase, one battery standard: graphene heating for the cold, active cooling for the heat, and every overcooled office, AC terminal, and temperature swing in between. No separate charger. No second battery. No proprietary lock-in.
EarthBae is among the first brands in Active Thermal Regulation to put graphene heating and active cooling on a single declared battery standard. It's a structural decision — an engineering choice, not a marketing claim.
On the cooling side, that standard powers two vests that do real work. EarthBae Air uses fan convection to accelerate evaporative cooling for a body in motion. EarthBae Chill uses liquid conduction to draw heat straight from your core in sustained, static heat. This is active cooling — not an ice pack that melts or a towel that dries. It pulls heat off the body, for hours, on demand, on the same battery that heats you in January.
And when any of those batteries reaches end of life, it doesn't become landfill. EcoDispose — EarthBae's free mail-in recycling program — takes back any 7.4V battery from any heated or cooling apparel brand, not just EarthBae's, at no cost. One battery to buy. One program to retire it responsibly.

Everything a buyer asks before they choose
What is an active cooling vest?
An active cooling vest is a wearable garment that uses a battery-powered mechanism to remove heat from the body. Active vests use either fans, which accelerate evaporative cooling at the skin, or circulated liquid, which draws heat through direct contact. They continue working as long as the battery has charge, unlike passive solutions such as ice packs, cooling towels, or evaporative-only vests, which lose effectiveness as they warm to ambient temperature.
EarthBae makes two: EarthBae Air uses fan convection, EarthBae Chill uses liquid conduction.
How is active cooling different from passive cooling like ice packs or cooling towels?
Passive cooling holds a fixed amount of cold. An ice pack starts at freezing temperature and warms toward body temperature; a wet towel cools through evaporation and stops working as it dries. Active cooling adds energy— a battery-powered fan or pump — that continues to do thermal work for hours. In sustained heat, passive solutions fade in the first 20 to 60 minutes; an active vest holds performance for the full battery runtime.
Should I choose fan convection or liquid conduction cooling?
Choose fan convection (EarthBae Air) if you are moving or active during heat exposure — outdoor work, athletics, commuting, summer events. Convection works by accelerating the body's evaporative cooling, which is most effective in low-to-moderate humidity when motion is part of the day. Choose liquid conduction (EarthBae Chill) if you are stationary in sustained, high heat — welding, foundry work, industrial trades, hot-environment professional roles. Conduction works through direct contact and is unaffected by ambient humidity or air movement.
Which cooling vest should I choose — EarthBae Air or EarthBae Chill?
Choose EarthBae Air if you are active and moving during heat exposure — outdoor work, athletics, commuting, summer events.
Choose EarthBae Chill if you are in a sustained high-temperature environment with limited mobility — industrial settings, welding, foundry work, outdoor positions with restricted movement, or environments where extreme heat is constant rather than variable.
Do the cooling vests use the same battery as EarthBae's heated products?
Yes. Both EarthBae Air and EarthBae Chill run on the same 7.4V battery standard as EarthBae Core (graphene heated hoodie) and EarthBae Heat (graphene heated vest). Same connector, same charging protocol, same battery. One battery investment covers the entire EarthBae ecosystem across all four seasons.
Does an active cooling vest work indoors?
Yes — indoor use is one of the most common scenarios. Offices that overcool then reheat through afternoon sun, warehouses without HVAC, server rooms, commercial kitchens, and indoor industrial settings all present thermal challenges an active cooling vest is built for. Both EarthBae Air and EarthBae Chill work indoors, outdoors, and across the transitions between them.
