Staying Warm/Thermal Comfort
Thermal comfort is achieved by balancing three factors:
1. Rate of heat production by your body
2. Insulation value of your clothing
3. Environmental temperature
With these three factors in mind, the simplest control over personal body temperature is altering the insulation value of your clothing. Insulations work by first trapping air; the more air trapped, the more efficient the insulation, and second by reflecting back the body.
Down Filled Coats
Our down filled coats are made with a densely woven nylon yarn that entraps fine white goose down feathers with up to 700 fill power. The outer nylon fabric makes the garment wind resistant and water repellent, and acts as a secondary cold weather shield to the down feathers it encases. Goose down feathers are extremely warm, and are known to insulate heat very effectively. Jackets filled with down feathers store warm air that has been created by the body within the insulation of the garment. A person's body radiates heat, and the down feathers in the jacket will store the heat creating an oven-like effect inside the jacket. The belts, high collars, zippers, thick plackets, and shaped design on many of our down coats further help to prevent heat from escaping, and the jacket will continue to get warmer the longer you wear it.
Parkas & Coated Cotton
Our parkas are crafted from a resin-coated Egyptian cotton and lined with 3M™ Thinsulate™ Insulation, which ensures warmth without the unnecessary weight or bulk. Additionally, this padding enables more freedom of movement and comfort to our garments. The polyurethane coating on the outer fabric makes the shell wind resistant, water repellent, and easy to care for. Some coated cotton styles feature a removable liner of 100% natural fur to guarantee extra warmth in addition to the Thinsulate insulation.
The original warmth-without-bulk insulation, 3M™ Thinsulate™ Insulation, is the brand trusted for warmth and used throughout the SAM collection. This padding throughout the bodies and arms of our coated cotton jackets and parkas traps and holds body heat while also allowing moisture to escape. The unique microfibers (or fine fibers) that make up thinsulate insulation work by trapping air molecules between you and the outside. The more air a material traps in a given space‚ the better it insulates you from the cold outside air. Because the fibers in thinsulate insulation are finer than the fibers used in most other synthetic or natural insulation‚ more fibers can be packed into a space, trapping more air, and reflecting back more of the body’s radiant heat.
