A lot of people will say that that they stick their hand warmers in their gloves before they go outside or go to work but almost all hand warmers advise you not to apply them directly to the skin so we cannot advise doing this, even with the disposable ones. Since you are supposed to have a layer between your skin and the warmer, we do think it is a great idea to hold the warmer with gloved hands in order to provide the most protection and warmth to your hands. When not in immediate need we recommend keeping the warmer in a small bag or sack for your safety.
