## Overview

The Heat Wave Instant Reusable Heat Pack is a premium, large 8x12" medical-grade heat pack made in the USA. It heats up to 130°F within 60 seconds via a simple metal disc click activation, providing long-lasting therapeutic warmth for muscle aches, joint pain, and cold weather comfort. Designed for portability and eco-conscious reuse, it’s ideal for everyday pain relief and emergency preparedness.

## Description

Heat Wave instant reusable hot packs are designed to offer comfort and warmth to every part of your body. Whether you are suffering from arthritis; lower back, knee, shoulder, wrist, or ankle pain; or you need relief from achy muscles and symptoms related to PMS, Heat Wave can help. Our large rectangular packs measure 8" x 12" and heat up to 130°F in under 60 seconds. Simply flex the metal heat activator and watch as the inner fluid begins to crystallize. Once your pack has started heating, it is ready for hours of long-lasting therapeutic warmth. When you are finished, place your heat pack in a pan of rapidly boiling water. Place a rag between the bottom of the pan and the hot pack. Keep it in the pot until the crystals completely dissolve - about 20 - 25 minutes - then simmer for 10. Remove the heat pack and allow it to cool to room temperature before your next use. Whether you have an emergency during a wilderness survival camp or are warming your hands and feet while watching your kids' cold-weather sporting events, Heat Wave hot packs offer the warmth you need when you need it. Heat Wave also makes the perfect addition to your emergency supply kit or survival gear and is small enough to fit in your hiking, camping, or hunting pack. Made from medical-grade vinyl and a nontoxic inner solution, our warmers are eco-friendly and designed to be used many times. Bent Grass Concepts began in 2005 trying to improve products for the golf industry. As time continued, many customers complained of back, neck, and shoulder pain. That's when we introduced our Instant Reusable Heat Packs and developed other products to help relieve pain. Order your heating pack today and feel the difference it can make!

Review: Great product, does exactly what is says. It take a bit of dedication to heat it ahead of time for future use so it gets less use than my bean bag, but it delivers nice even heat to a large area at the same temperature for more than 20 minutes.
Review: This is the second time to purchase it and it isnt working this timeee !!!

### ⭐⭐⭐⭐⭐ Review
*by P***R on 3 January 2013*

This is a very useful and very neat product! It works exactly as described -- click the metal disc, and the clear liquid instantly starts turning into a crystal-like product and produces nice heat for a good hour. Boil it until it's clear again, and it's ready for another round. Ingenious! Since the outside of it is ordinary plastic, I would recommend you wrap it in a towel before boiling it, to avoid having the plastic touch the sides or bottom of the pot. Otherwise, the plastic could melt. I've also found that, after boiling it, the pack stays warm for a while, so you can actually use it again when it's fresh out of the boiling water, while it's still warm -- it stays warm for a good long while. Then, once it cools, if you're ready for more, it's ready to be re-activated. Pretty neat! I'm considering buying more of these in different sizes. Excellent product -- I will be using it a lot.
