At GOKOZY, we don’t just make heated jackets—we build winter gear you can actually trust. Every product goes through rigorous testing before it reaches your hands. Why? Because when it’s freezing outside, you need gear that performs. No excuses.
1. Heat Distribution Testing
We use thermal imaging cameras to ensure that every heating panel in our heated jackets delivers consistent warmth across the chest, back, and collar. No cold spots. No uneven heat. We even test the heat-up time to guarantee you feel warmth in seconds—not minutes.
2. Real-World Wear Simulations
It’s one thing to look good in the studio. But we want to know how our heated jackets perform during a 5am commute, a snowstorm hike, or an afternoon at a windy job site. That’s why GOKOZY tests in real cold-weather environments—on real people, not mannequins.

3. Battery & Safety Protocol
All GOKOZY batteries used in our heated jackets are tested for overheat protection, short-circuit resistance, and consistent output in low temperatures. While our power banks are compact and removable for travel, we always recommend checking the latest TSA guidelines before flying. Each jacket is made with water-repellent (not waterproof) fabrics and built with multiple safety layers for stable, reliable heating.
4. Machine Wash Stress Tests
Heated jackets should be easy to care for. That’s why we test our gear through multiple wash cycles—battery removed—to ensure heating elements remain intact and functional. No peeling, cracking, or shorting out after washing.

5. Fabric Durability & Comfort Checks
It’s not just about the tech—it’s about how it feels. We inspect every heated jacket for stitching strength, fabric softness, and stretch flexibility to make sure it’s not only warm but wearable. You get performance gear that’s also comfortable for all-day use, no matter the conditions.
Why It Matters
We’re not interested in gimmicks. At GOKOZY, we design heated jackets to do one thing extremely well: keep you warm—safely and reliably. Every test we run brings us closer to that mission.

So the next time you zip up a GOKOZY heated jacket, know that it’s been through the cold, the rain, the wash, and every challenge winter can throw at it—before it ever touches your skin.
