Stanfield's Clothing: Merino Wool, Two-Layer Thermal, and Heritage Wool
Stanfield's was founded in 1856 and has manufactured wool clothing at its Truro, Nova Scotia factory since 1870. This Stanfield's lineup from Cleanflow spans four product families: heritage wool henleys, two-layer thermal underwear, 100% merino wool base layers, and cotton basics.
Stanfield's clothing fits construction, utility, oil and gas, forestry, and general outdoor work in Canadian winters. Each product below links to its product page.
