YOUR ANSWER TO FREEZING-STIFF COLD: You’re operating in freezing weather, but your task doesn’t necessarily involve intense physical effort. With the Delta OL 4.0 Tactical Winter Jacket you’ll not only defy the numbing cold but also stay fully protected from conditions that alternate between freezing and thawing, wet and snow. THERMAL INSULATION THAT ACTUALLY WORKS: The Delta OL 4.0 Tactical Winter Jacket is insulated with G-LOFT, a hollow polyester fiber filling that lines the torso and sleeves. Those fibers capture warm air from your body, meaning the jacket needs less bulk to provide superior inner warmth. 100% WINDPROOF & HIGHLY WATER-REPELLENT: You can depend on G-LOFT to keep you warm and dry even in the worst wet weather because it doesn’t absorb moisture. And owing to its high compressibility, the jacket springs right back to its ready-to-start-working shape the moment you pull it out of your backpack. Truly the best balance of volume, weight, and reliability. STAY IN CONTROL OF YOUR COMFORT: Put on the Delta OL 4.0 Tactical Winter Jacket and you’ll be warm but not overheated. If you do start to feel too warm, all you have to do is open the integrated, smooth-gliding VISLON YKK zippers in the armpits to expel excess heat. These top-quality zippers are designed to avoid getting snagged on the adjacent fabric and to let you fully open them with just one quick move. ENHANCED DURABILITY WHERE IT COUNTS: The parts of any winter jacket that usually wear out fastest are the elbows and lower back. Not on the Delta OL 4.0 Tactical Winter Jacket. We’ve reinforced those areas with abrasion-resistant CORDURA fabric, known the world over for its ability to withstand some of the most severe abuse imaginable.
