  • Unconstructed is a term used to describe a soft, not fully lined tailored jacket. Because there is no lining, its open interior requires meticulous finishing with piped seams. Unconstructed jackets are more costly to make than fully lined jackets because it requires greater attention to detail. Advantages include greater breathability than a fully lined jacket and lighter weight.
  • Also called supination, underpronation is a type of foot pronation that results in insufficient inward roll during the gait cycle (walking and running). Underpronation is more prevalent in people with high arches. People who underpronate should choose running shoes with ample cushioning and avoid motion-control features. Insoles with additional arch support may also help.
  • UPF sun protection rating is a method of rating that indicates how effective a product is in protecting you from harmful UV rays. The system was developed by the Australian government, in part because Australia (with its high level of exposure to the sun) has the highest incident of skin cancer in the world. The UPF sun protection rating table is as follows: UPF 15–24 (“Good”) provides protection from 93.3% to 95.9% of UV rays, UPF 25–39 (“Very Good”) provides protection from 96.0% to 97.4% of UV rays and 40 and over (“Excellent”) provides protection from 97.5% or more of UV rays.
  • Invisible ultraviolet (UV) light rays from the sun that can cause serious skin and eye damage. Extensive exposure to UV rays can lead to skin cancer and cataracts. Different levels of ozone, as well as seasonal and weather variations, cause varying amounts of UV radiation to reach the Earth at any given time. Protection can be afforded by using effective sunscreen and wearing a hat and sunglasses with a “100% UV protection” rating.
