23 Years of Thermal Engineering: Your Trusted Partner in Intelligent Warming Systems

SINCE 2003: PIONEERING THERMAL TECHNOLOGY

Since 2003, MEC ADDHEAT has dedicated itself to the R&D and advanced manufacturing of battery-powered wearable thermal systems. As a true pioneer in smart warming technology, we vertically integrate and manufacture all core components in-house—including precision NTC controllers, flexible heating modules, and high-safety battery packs. By maintaining 100% engineering authority over every process, we deliver uncompromised safety, constant innovation, and absolute supply chain reliability.

ETHICAL CRAFTSMANSHIP & SCALABLE CAPACITY

Powered by over 400 skilled professionals, our modern facilities deliver a monthly output exceeding 200,000 thermal modules. Unlike traditional piece-rate factories that sacrifice quality for speed, we operate on a fixed hourly wage system. This prioritizes worker well-being, workplace safety, and meticulous precision over rushed quotas. Driven by lean JIT scheduling and high-precision automation, every module is crafted with ultimate care and structural consistency.

GLOBAL COMPLIANCE & RIGOROUS QUALITY

Backed by rigorous lab validations—including automated testing that guarantees over 95% thermal efficiency retention even after 50 wash-and-dry cycles—our heating systems achieve industry-lowest defect and return rates (<0.1%). Fully certified under major global standards (UL, CE, FCC, RoHS), our user-centric designs elevate the end-consumer experience while serving as an unshakeable shield for your brand’s market reputation.

LONG-TERM PARTNERSHIPS & BRAND DEDICATION

Trusted by over 50 premier apparel, outdoor, and technical gear brands across North America, Europe, and Asia, we build long-term strategic alliances—never one-off transactions. While we operate behind the scenes, we view your consumers’ safety and satisfaction as our own. Serving as your reliable manufacturing backbone, we empower our B2B partners to win market share and build maximum customer loyalty.

I absolutely love my heated jacket! I get super excited when ever anyone asks me why my jacket is lighting up. I have both a jacket and the down coat. Over the few years of me raving about how much a love these products my husband said he wanted one. So for his birthday i got him the down jacket and he really likes it too! I recommend this brand to anyone who asks!

Bought this vest for my husband who works in freezing temperatures anywhere from 8 to 10 hrs a day during the winter. He says the vest has been a lifesaver and works great under his other layers of a thick, heavy sweater and jacket.

Love my vest!! I am a landscaper in the Pacific Northwest and winters are damp and chilly! Nothing is better than having this vest especially first thing in the morning before I start moving. I have bought seven of these. One for each of my family and a couple co workers. They all love their vests.

I bought the heated vest for a ski trip. It worked great!! I wore it under my shell jacket and was completely warm the entire trip..even the morning I skied and it was 5 below zero. Love the fact that I can adjust the temp via bluetooth on my phone! I am a duck hunter and most of those mornings are really cold. This vest will be my new go to item to wear underneath my hunting jacket!! It's a great product if you want to keep warm!!

Bought the vest, just in time too. 100% needed it on a cold morning bike ride as the first test go in the wild. It was interesting to notice that when your core is warm, your extremities stay warm. I noticed that even with just the vest it made my arms, hands, and legs warmer too. Might have to buy a second one for the perpetually cold office I work at.

Purchased for my 84 father who likes to be outdoors walking and on his bike. He has been wearing it now for 3 weeks and used 4 times and just loves it. He wears on low and lasts him his entire outing with a long sleeve underneath the vest and a light jacket over the vest.

I purchased the Venture Heat vest in December. I received the vest quickly and began using it immediately. I am a golfer and don't like much on my arms so a vest is perfect. I found that I can play golf in the coldest days in Virginia and with my new heated vest I am very comfortable. I walk the course for exercise and now I find golf a good source of exercise even in winter conditions. I would purchase this vest again and will likely give a couple as gifts to family members.
