The Triple Heat Pack is Shin Bio’s largest heat pack, shaped to drape naturally across your neck and shoulders or wrap your upper back. At 420mm wide it covers the full upper back in one application.

Click the disc and within seconds the gel warms to a soothing, therapeutic heat that lasts and lasts. No microwave, no batteries, no cords.

Dimensions: 420mm × 130mm  ·  Heat: Long-lasting  ·  Weight: 180g

Inside the Triple Heat Pack is a sealed pouch of sodium acetate solution and a stainless steel disc. Flexing the disc triggers an exothermic crystallisation reaction — the gel warms to a soothing, therapeutic heat within seconds. The reaction is fully reversible: boil to reset and use it again and again.

  • Medical-grade PVC outer pouch
  • Food-grade sodium acetate solution
  • Stainless steel activation disc
  • TGA-compliant for therapeutic skin contact

Drop the pack into a saucepan of boiling water. Submerge fully and boil for 10–15 minutes (timed from when the water is boiling) until the gel turns completely clear. Remove with tongs, cool to room temperature, then it’s ready to click again. Never microwave — boiling water only.

Just water and food-grade sodium acetate, sealed inside medical-grade PVC. The metal disc is stainless steel. TGA-compliant for therapeutic use on skin.

Again and again. Once it cools, just boil it to reset and it’s ready to use all over again.

It warms up quickly to a soothing heat — up to around 54°C in the larger packs, though how warm it feels and how long it lasts depends on the size and the room around it. Plenty of comfort where you need it.

Bring a pot of water to the boil, then drop the pack in for 10–15 minutes (timed from when the water is boiling) until all the crystals dissolve back to clear liquid. Let it cool to room temperature and it’s ready to click again.
