Zip up the storm flap sewn into the decorated Helly Hansen Men's High Visibility Orange/Charcoal Alta Insulated Jacket with CSA to enjoy full body protection against cold temperatures. One-hundred percent nylon lining traps body heat to create an additional layer. Polyurethane coating prevents unexpected deluges from drenching your skin. The extended back improves mobility to help you access tight spots on work sites. Wear the multi-purpose jacket in the field and keep it on after work when you decide to ride your bicycle at night. Attach your company logo on the large imprint area to introduce your brand to potential customers at business seminars and conferences.
