Tin Cloth has been a staple Filson fabric for durable weather protection in the forests of the Pacific Northwest for more than a century. This Tin Cloth PrimaLoft® Vest combines that traditional ruggedness with PrimaLoft®’s class-leading lightweight insulation. The Tin Cloth shell fabric is a tightly woven 100% cotton waxed canvas that’s been treated with liquefied wax under high heat and pressure. This forces the wax into the core of each cotton fiber, for lasting water resistance. The fabric’s tight weave makes it exceptionally abrasion-resistant. It also makes it difficult for any punctures to develop into tears. Our oil finish Tin Cloth can be rewaxed as often as needed to maintain water-resistance for decades of reliable service. PrimaLoft® is a lightweight synthetic insulation engine
