Improve your outdoor experience with the reusable haago hand warmers. Each warmer delivers up to 8 hours of heat and can be used multiple times within 10 days. Simply open the packaging, activate the warmer and enjoy the warmth. Re-close the warmer in the airtight packaging to preserve residual heat for later use. For example, do you use the warmer for 1 hour and turn it off again? Then there will be 7 hours of heat left.
