Sitka Gear Grindstone Work Jacket hunting jacket
Model: 600507-CY-M
Description
Built for hard work, cold weather, and demanding days outdoors, the Grindstone Work Jacket combines exceptional durability, reliable insulation, and complete wind protection in a rugged layer designed to perform when conditions get tough.
The updated Grindstone Work Jacket retains proven PrimaLoft® Silver insulation, providing dependable warmth without excessive bulk. Whether you're working outside, preparing for hunting season, managing property, or tackling chores around camp, the insulation helps keep you comfortable when temperatures drop.
100% Windproof Protection
Cold wind can quickly turn a long day outdoors into an uncomfortable one. That's why the Grindstone Work Jacket features WINDSTOPPER® technology by GORE-TEX LABS, providing 100% windproof protection to help prevent biting winds from cutting through your outer layer.
The result is a warm, protective work jacket that's well suited for hunters, farmers, ranchers, land managers, tradesmen, and anyone who spends serious time working outdoors in cold and windy conditions.
Exceptional Gore + CORDURA® Durability
What sets the updated Grindstone apart is its exceptionally durable laminated fabric, developed through a collaboration between Gore and CORDURA®. This rugged construction represents a new level of durability, giving the jacket the toughness needed for demanding work environments and repeated outdoor use.
From cutting firewood and working around the farm to hanging treestands, scouting property, and completing preseason habitat work, the Grindstone Work Jacket is engineered for the kind of jobs where ordinary outerwear can come up short.
