The original high-performance fabric Ventile® that saved many an Arctic Ocean downed RAF pilot's life in WWII is back in a versatile men's field jacket that will weatherproof your adventures. The soul of this durable jacket is its Ventile cotton shell. The long-staple fiber is woven so densely that wind can't penetrate it and water runs right off it. When conditions get soaking wet, the fibers swell to keep water from penetrating. Because its remarkable weatherproofing ability is achieved without coatings, just pure cotton, the jacket breathes wonderfully. You've no fear of feeling clammy when the rain stops. Seam sealing ensures extra protection. The interior is quilted and lightly insulated. Ventile in action, unlike synthetics, is nearly soundless, making it truly the finest field fabric. UK.
