Until now, insulation could only hold in the heat you produce. But our Insolator Vest contains revolutionary SOLARball® insulation that transforms the sun’s infrared energy into instantaneous warmth – no battery pack needed. Scientists have a name for this phenomenon: exothermic reaction. You’ll just call it not freezing your a$$ off on the job. Better yet, SOLARball insulation is light in weight, packable and machine washable. We’ve packaged this incredible insulator inside a windproof, abrasion-resistant and water-repellent nylon shell.  Added a 2-way zipper and hem cinch. And built in 9 total pockets. It’s outerwear you’ll really warm up to.

NOTE: Do not wear if you have a pacemaker.
