Lifesystems Reusable Heating Gel Hand Warmers Twin Pack
Lifesystems Reusable Heating Gel Hand Warmers are manufactured from non-toxic sodium acetate and water. When you click the metal disc inside the gel, it sparks the crystallisation process that turns the gel form a liquid state to a solid state. This phase change releases energy as heat, with a maximum heat output of 54°c. Depending on the weather conditions, the heat output from the gel will last for up to 90 minutes.
To 'recharge' the gel pads, you just need to place them in boiling water for a few minutes until the crystals have dissolved and the gel runs clear. The process can then start allover again, but remember to let the gel pads cool down first before handling.
Lifesystems reusable heating gel hand warmers are ideal for instantaneous heat in cold weather and are suited for warming cold hands when walking and hiking. In emergencies they can provide a quick source of heat for people with injuries, but the gel pads should not be applied directly to their skin.
