The insulated work vest made of Tin Cloth fabric combines our legendary waxed cotton and innovative PrimaLoft® insulation for a multi-purpose layer with the characteristics of Filson vests from the last three decades. - The shell is made of oil-finish Tin Cloth fabric, with roots dating back to the rainy forests of the Pacific Northwest in the 1920s and a proven ability to withstand the harsh conditions encountered by foresters, hunters, and artisans. - The tightly woven duck canvas forms an almost impenetrable barrier to thorns, brambles and abrasion and, thanks to its robust waxed finish, shakes off water and mud without any problems. - 60g PrimaLoft® Gold insulation provides lightweight warmth that mimics goose down, but unlike goose down, it retains warmth even if it gets wet. - This durable vest is lined with signature Cover Cloth fabric with a dry finish for natural comfort, and its teardrop hem keeps you covered when bending or climbing. - The sliding front hinge is made of metal for guaranteed reliability. The ribbed collar is a special blend of wool, for a warm feeling that only wool can offer. - Pockets are flannel lined, concealed chest pockets and multi-purpose slit pockets. - The work vest in insulating Tin Cloth fabric: made with the best materials, designed for work and just as functional in the field as on the construction site.
