A workwear collection so tough, Sitka's product team ran out of durability tests. The updated Sitka Grindstone Work Jacket 2025 retains its Primaloft® Silver insulation for plenty of warmth and still boasts 100% windproof protection thanks to WINDSTOPPER® by GORE-TEX LABS. But a new exceptionally durable laminated fabric – the result of a collaboration between Gore and Cordura® - marks our most durable layers to date.
