The longer you stay outside, the more fun you have. Next time, take a Zippo Hand Warmer along to the campsite, stadium, ski slope or deer stand. It provides up to 12 hours of gentle, consistent, odorless heat - more than disposable warmers - and they’re refillable with Zippo Premium Lighter Fluid, so they don’t end up in landfills. Each Hand Warmer features all metal construction and comes with a fleece warming bag, so the heat is always gentle on your skin. The Zippo Hand Warmer was awarded the Seal of Approval by the North American Hunting Club.
