Thorlo Hunting Extreme Cold

Sock specialist Thorlo (888-846-7567; www.thorlos.com) offers a full line of hunter-friendly socks (all come with a 30-day Money Back Guarantee) but its Hunting Extreme Cold sock ($23) is a stand-out when temps dip. In addition to simply being thicker (especially in ball and heel) than many boot socks, the Extreme Cold offers a 100-percent worsted wool toe area, combined with a wool/Thor-Lon (acrylic blend) elsewhere. These are seriously warm socks. To extend life the company recommends washing/drying inside-out and using fabric softener. — Mark Melotik

Thermacell Heated Insoles

The impressive new Heated Insoles ($130/pair) from Thermacell (866-753-3837; www.Thermacell.com) might just be the best thing to hit cold-weather bowhunting since the insulated boot. These wireless, rechargeable wonders work with help from a remote control you carry in a pocket. Choose from three settings: Medium (about 5 hours of 100 degrees F), High (111 degrees F) or “No Heat,” which puts the insoles in “sleep” mode when your feet are warm. The ultra-compact remote is powered by one replaceable Lithium battery (CR2032) designed to last for two years under normal use; the included charger can be used to charge lithium-ion batteries embedded in the soles “well over 500 times.” Charging takes three hours. — Mark Melotik
