Sitka Kelvin Aerolite Jacket

The Sitka Kelvin Aerolite Jacket delivers high-performance warmth with minimal bulk, making it ideal for backcountry hunts, scouting, and everyday cold-weather wear. Built with synthetic PrimaLoft® Gold insulation with Cross Core™ technology, this jacket replicates the compressibility and warmth of down while maintaining reliable warm-when-wet performance — a major advantage in unpredictable conditions. The lightweight insulation is infused with silica aerogel, a nearly weightless thermal material composed of over 95% air, maximizing warmth without added weight. Designed with a durable, 20-denier polyester shell and DWR finish, the Kelvin Aerolite Jacket resists light precipitation and enhances layering flexibility. Additional features include a fitted hood for low-profile warmth and concealment, gusseted stretch cuffs for smooth layering, and a deep, zippered chest pocket to securely store essentials. This versatile jacket seamlessly transitions from outdoor excursions to everyday comfort.
