Sitka has developed a system of hunting gear, merging the latest technology together with a mountaineering philosophy. The best technology, fabrics, designs and construction create hunting gear that outperforms mere “clothing”. It’s not just something you wear. This is a performance-driven system specifically created to be hunter-friendly. The Kelvin Jacket is perfect for core-warming layering. It is lightweight, packable, and is insulated with a large dose of PrimaLoft® and has a layering-friendly polyester shell. Optifade™ camouflage from W.L.GORE is the first and only concealment system ever scientifically designed around the way a hunter’s prey views the world. It’s the only concealment system to combine a symmetry disrupting macro-pattern with the fractal-geometry-based micropattern designed to become nothing in the eyes of prey at engagement ranges of 20 meters and beyond. Imported. Sizes: M-2XL. Camo patterns:OptiFade™ Concealment Forest, OptiFade™ Concealment Open Country.
