Grabber Warmers air-activated heat pack

Grabber Warmers is a pioneer in the air-activated heating industry, originally bringing Japanese heat-cell technology to North America. These single-use packets contain a mix of iron powder, water, salt, activated charcoal, and vermiculite that generates heat when exposed to oxygen. They are widely used by outdoor enthusiasts, athletes, and workers in cold environments.

While the brand has its roots in the United States, it became part of a larger corporate portfolio through acquisitions. It was previously owned by the Grabber Construction Products group before being acquired by Kobayashi Healthcare, LLC. As a result, the brand now benefits from the research and development capabilities of its Japanese parent company, which is a global leader in heat-activated wellness products. Manufacturing of these packs typically occurs in the United States or Japan, depending on the specific product line and regional distribution needs.
