What does Helly tech protection mean for the company logoed Helly Hansen Men's Black Hood Jacket? It means the decorated workwear enjoys protection against high winds and heavy rain. One-hundred percent breathable polyester takes as much punishment as you can deliver on the job and when you get away from it all in the backcountry. Two ply fabric design produces the perfect jacket for active professionals. Adjust the bottom hem to ensure the right fit for all day wear. Add a custom logo on the large imprint area to get the word out about your company during business trips.
