To fight the cold and make our range trips more comfortable there are products on the market to keep our hands, body and feet warm whether it’s just plain frigid or we’re trudging around in the snow. There is one company that Steve and I both like and have written about several times over the last few years and that’s the heated insoles and now hand warmers and pocket warmers from Therma Cell.

Hand warmers

Hand warmers

The product lineup this year consist of the Pro Flex heated insoles, Heat Pack pocket warmers and the smaller Heat Pack hand warmer. All of the products operate on rechargeable batteries via a USB connection of any type. Standard run time on the medium setting is a stated 4 hours. It’s been my experience that the 4 hour time is underestimated. I’ve had them set on high for 5 hours and they were still putting out heat. The units can be recharged in approximately 4 hours but again my times have been closer to 3 hours for a full charge. The hand warmers run for an advertised 6 hours but they do run a bit longer than that.

The hand warmers are slim, lightweight and fit easily into a set of gloves no matter if they have a pocket for such devices or you just slip them into the back of the glove. The hand warmers have three settings low, medium and high. They are controlled by a push button on the unit. One push and a single green light flashes. Two presses and you have medium heat with two flashes while three presses places the unit on hight heat with three flashes. I usually start out on high until my hands are warm then knock the setting back to medium. As slim and lightweight as they are they don’t interfere with your gun handling whether it’s a handgun, rifle or shotgun. Each box comes with two hand warmers with individual chargers.The MSRP is $79.99. The larger pocket warmers have an MSRP of $69.99.

The heated insoles come in various sizes for men and women. Each insole can be trimmed to fit each shoe. The Pro Flex insoles each have a rechargeable battery which fits into a recess in the heel of the insole. Again charging is by USB connection. Each insole has it’s own charger.MSRP: $184.99.

A very nice feature of the insoles is a small remoter control that can be carried in a pocket or on a key chain for instance. With the remote there is no need to remove your shoes to adjust the heat setting. The insoles also have settings of standby, medium and high.

    What happens to those shoe insoles when your feet get wet from melting snow? And the battery packs, are they the hoverboard gonna catch fire lithium-ion type?

      They’re probably the carry-a-cellphone-in-your-pocket-every-day lithium-ion type.
