Fortress Extreme Jacket Midlayer Aeris 500, Black
Built for extreme conditions, the Extreme Jacket delivers powerful warmth without the need for bulky layering. Designed to be worn under a shell, it replaces traditional multi-layer systems with a streamlined, high-performance solution.
Featuring a patented layer system, the outer shell repels wind and water while AERIS™ 500 insulation (½" / 13mm loft) traps heat and wicks moisture away from the body. The advanced synthetic insulation maintains its loft and warmth even when wet, ensuring reliable performance in harsh weather.
Constructed with a 100% polyester micro rip-stop taffeta shell with DWR finish and a 100% polyester mesh lining, this jacket offers durability, breathability, and long-lasting performance. It provides excellent moisture control, windproof and water-resistant protection, and dependable comfort in demanding environments.
Designed for mobility and fit, it features lower side slits for enhanced movement, an adjustable drawcord waist for a secure fit, and a full dual-head YKK center front zipper for versatility.
