While camping in the great outdoors, it’s necessary to learn how to do without certain comforts of the home. Seattle-based heritage outdoors brand STANLEY has recently introduced an update to its hallmark food system – so that a warm meal isn’t one of those lacking comforts. The Mountain Vacuum Food System incorporates its own internal spark to both heat and preserve a can’s worth of food for up to 13 hours. This vacuum-insulated jar is housed in a stainless steel shell that is both rust-proof and, naturally, BPA-free. Pick up this nifty solution on Amazon now.
