ArcticShield® High-Efficiency Boot Insulators keep your feet toasty warm, even at the most extreme temperatures. Using patented Arctic Shield RE-tain™ technology, this incredibly efficient insulator has been proven effective at -109ºF, making it the only option for bitter cold weather. Lightweight, tough and naturally water resistant, these insulators simply slip over your boots for total warmth even in below-zero temps, without the use of chemicals or batteries. Weighs just 9 oz. Rolls up and stuffs easily into a pocket. One pair. Imported.
ArcticShield's exclusive RE-tain™ technology utilizes a multi-layered thermal barrier that captures and returns up to 97% of your body heat. By positioning an aluminized middle layer between advanced thermoplastic fabrics, this heat reflection and return method is more effective than thick traditional insulations that only slow body heat loss. Innovatively thin and unbelievably warm, this clothing provides great insulation and breathable wind- and waterproof protection as well.
