In the most frigid conditions, work must go on—through snow drifts, howling winds and plummeting temperatures. Enter the Terra® Stormbreaker with its eight-layer TERRASPHERE+™ liner engineered with PrimaLoft™ and Thermolite™ insulations, plus a Mylar heat-radiating film. Comfort rated and tested down to an astounding -60°C/-76°F, it’s built for comfort and warmth where few dare to tread. The high-traction rubber outsole stays flexible in extreme cold as the micro-diamond texturing and sawtooth lug profile dig into the frozen earth. A CSA Grade 1 composite toe, composite plate and electric shock resistance keep you safer on the job.
