What Our Customers Are Saying
-
Finally, My Entire Shift is Bearable
"I'm on construction sites in Minnesota where it hits -10°F regularly. I used to layer up like crazy and still couldn't make it through without taking warm-up breaks. Core Warmth changed that. One vest, 10 hours of heat, and I'm actually comfortable working. My whole crew saw it and now half of them ordered one."
-
My Commute Went from Dreaded to Tolerable
"I walk 15 minutes to the train every morning in Chicago, and winters are brutal. I used to arrive at work frozen and miserable. This vest heats up in under a minute, fits perfectly under my coat, and I actually don't hate my commute anymore. Worth every penny."
-
Sat in My Stand for 6 Hours—Got My Buck
"Hunting in Pennsylvania in December means sitting still in freezing temps. I've tried everything, but nothing worked like this. The battery lasted my entire morning hunt (6+ hours), the vest was completely silent, and I stayed warm enough to wait for the shot I'd been after all season. Game changer."

Frequently Asked Questions
How long does the battery actually last?
How long does the battery actually last?
Our battery delivers 12+ hours on low heat, 8 hours on medium, and 5 hours on high—verified through rigorous testing. Unlike competitors who exaggerate runtime, we guarantee these numbers. The 10,000mAh capacity means you can work a full shift, hunt all morning, or commute all week on a single charge. We also offer spare batteries ($39) if you need extended use or back-to-back days in extreme cold.
Is it really machine washable?
Is it really machine washable?
Yes! Simply remove the battery from the interior pocket and toss the vest in your washing machine (cold water, gentle cycle recommended). The carbon fiber heating elements are fully sealed and waterproof. Hang dry or tumble dry low. This is real gear built for real life—you shouldn't have to baby it. Thousands of customers wash their vests regularly with zero issues.
Will this fit under my work jacket or coat?
Will this fit under my work jacket or coat?
Absolutely. Core Warmth is designed as a slim mid-layer—it fits comfortably under jackets, coats, safety vests, and even blazers without adding bulk. The lightweight design (under 1 lb without battery) and flexible fabric mean you can layer it seamlessly. Many customers wear it under their uniform jackets for work, then under a parka for weekend activities. Check our sizing guide to ensure your best fit.
Is the heating safe? Will it overheat or malfunction?
Is the heating safe? Will it overheat or malfunction?
Safety is our top priority. Core Warmth uses UL-certified lithium-ion batteries and carbon fiber heating elements that distribute warmth evenly without hot spots. The vest includes built-in overheat protection and auto-shutoff features. You control three heat levels (low, medium, high) so you're always comfortable, never too hot. Our batteries are the same safe technology used in millions of devices worldwide. Plus, every vest is backed by a 2-year warranty.
Is this only for extreme cold, or can I use it in milder weather?
Is this only for extreme cold, or can I use it in milder weather?
Core Warmth works in any cold condition. The three heat settings (low at 113°F, medium at 131°F, high at 149°F) let you dial in perfect comfort whether it's 50°F and breezy or -10°F and brutal. Many customers use low heat for fall mornings or spring evenings, then crank it up when winter hits hard. It's adaptable—use only what you need.
What if I don't like it?
What if I don't like it?
You have 30 days to test Core Warmth in real conditions—no risk, no pressure. If you're not satisfied for any reason, return it for a full refund. We cover return shipping, and there are no restocking fees or hidden charges.
