Stuffy sweaters? Leave ’em on the launch pad and go for something with smarter construction. Rocket Science sweaters are powered by Outlast® technology – originally developed for NASA to defend astronauts from the extreme temperature swings of space. The phase-change material in the fibers absorbs and releases heat slowly, leveling off temperature fluctuations as you go from heated cab to the frigid jobsite. We blended it into a midweight 55% cotton/45% Outlast acrylic fabric that feels great from early fall all the way through spring. It’s a moonshot in sweater innovation!
