Tactical Vest /Semiconductor Tech | Fast Temp Control | Dual Fans | T-Ducts | Multi-Pockets | Ergonomic Design

Tired of summer’s suffocating grip? Done with flimsy cooling towels and clunky ice packs that sabotage your adventures?


This smart climate control vest integrates a dual-mode semiconductor module (cooling/heating) and an ergonomic T-shaped airflow channel, powered by a standard 12V mobile power bank.

Just like your phone needs thermal protection, your body also needs a sophisticated climate system.

Traditional cooling vests force you to choose between weak airflow and bulky ice packs. ColdSpark breaks that dilemma by integrating both cooling methods into one system.

The semiconductor plates cool your skin directly, while a high-powered fan drives airflow through a precision-engineered T-duct. This dual cooling approach delivers faster cooling with reduced energy consumption—no trade-offs, just lasting comfort.

Put it on and it will instantly cool you down by 7℃(44°F)


Where ordinary cooling vests neglect aesthetics, ColdSpark redefines cooling vests with tactical elegance.Crafted from abrasion-resistant nylon and engineered breathability, its rugged silhouette conceals numerous quick-access pockets for tools, phones, and survival gear. The utilitarian tactical finish makes it essential outdoor armor.

Watch roofers securely clip drills into high-capacity pockets while outdoor warriors organize survival kits on the chest-mounted MOLLE system. This isn’t just a climate-control hub – it’s your battle-tested ally against the elements.

Our 127 P-N semiconductor array targets your scapula’s pulse points – not just cooling skin, but regulating core thermal stress, Achieve 18°C(64°F) drop in 60 seconds


Don’t settle for noisy ‘high-speed’ fans that drain batteries. ColdSpark’s 50CFM turbo airflow (6,000 RPM) works smarter

Dual Vortex Channels push 22% more air to critical sweat zones

Pair with any 20,000mAh power bank for:
✓ 4-6 hours ice-cool endurance (Cooling Mode)
✓ 6-8 hours toasty runtime (Heating Mode)

From sunrise hikes to night shifts – your climate armor never quits.

Removable design for easy cleaning and maintenance

3 levels of temperature adjustment
