Zippo Hand Warmer Instructional Video:Cheap, disposable hand warmers are readily available, inexpensive and work pretty well. I've used them skiing and have nothing bad to say about the performance of the product. Only that they add to our rapidly growing landfills. On the other hand, Zippo has always created products that will last a lifetime with proper care and maintenance. Living in a pretty cold environment, I have the opportunity to test the Zippo Hand Warmer daily. So far, it lives up to the Zippo standard providing a comfortable, reliable heat. Let's make a concerted effort to break the disposable mold and start using more reusable products like the Zippo Hand Warmer. Final thoughts: Durability, classic design and functionality are all attributes that come to mind when describing the Zippo Hand Warmer. However, this reusable design does include a few minor compromises. Once the measured fuel has been added and the catalyst started, there is no way to stop it other than let it run it's course. So make sure you plan ahead when measuring the fuel needed. Also, the addition of a flat bottom would be nice since keeping it upright for 2 minutes after filling is a requirement. All in all, a well built product but I'd consider a second hand warmer for each pocket. And if you're not already part of the Crate Club, get off your ass and sign up!
