Cold weather protection for your shipment. This air-activated heat pack generates steady warmth for up to 40 hours, helping protect temperature-sensitive livestock and supplies in transit during cool or cold conditions.
Add it to your order whenever overnight lows are a concern. Once exposed to air the pack begins warming on its own, and it travels inside your insulated packaging to help hold that warmth in during shipping.
