Spiewak offers the selection and flexibility to mee the variety of needs that exist throughout the Uniform and Industrial market. We make it easier for you to find the right jacket to fit your needs. Since everyone is unique, and reacts to cold weather differently, your comfort range in real conditions may vary from the temperature ranges we list. The specific climate or geography for which a jacket was designed is only one aspect you must consider when choosing the right outerwear.
So, what other factors should be considered?

	Temperature alone is a very poor way to rate outerwear. Wind, humidity, precipitation, exposure time, and dramatic shifts in conditions are all factors which affect comfort.
	Some positions require nearly all time to be spent outdoors. Whereas others are going back and forth between a warm building and harsh outdoor conditions several times during a work shift. Additionally, the level of physical activity greatly affects body temperature. Therefore, the need for versatility and variances caused by working conditions is another important factor to consider.
	Wearing other apparel such as hats, gloves, sweatshirts, or insulated undergarments can have a great impact on the level of thermal protection a jacket will provide. Proper headwear, in particular, can cut heat loss by over 30%.
	There are tremendous differences in personal metablolism that affect how much protection is needed. Some people are comfortable in greater heat, while others prefer colder conditions.
	Proper layering of undergarments, chosen and sized to promote moisture transmission and freedom of movement will also have an impact on your comfort level.
