The UV Protection Series include several different fabrics that all possess UPF ranging from 40 to 50+. The fabrics are either polyester-Spandex® blend or nylon-Spandex® blend. Polyester and nylon, due to their chemical composition and tighter weave, offer much higher UV protection than that of any cotton garment. Macro brand UV Protection Series offer excellent UV protection fabrics that are good for outdoor exercise and lifestyle under strong and long sunlight exposure. Most colors are with UPF 50+ ratings based on the AS/NZS 7399-1996 (Australian Standards) test.

UVA (Ultraviolet A) are long-wave rays that usually do not cause burns, but penetrate the skin more deeply. They are thought to be the main culprit behind the wrinkling and leathering of skin. UVA is NOT blocked by the ozone layer.

UVB (Ultraviolet B) are short-wave rays that cause burns. They strike your skin more forcefully, but don’t penetrate deep. UVB is partially blocked by the ozone layer. The thinning of this layer has caused more of these damaging rays to reach the surface.

UVC (Ultraviolet C) are even shorter (and thus more powerful) rays. They are lethal to plant life and small organisms. But they are completely blocked by the ozone layer. In the future, when the ozone layer gets even thinner, this could be a dangerous issue.

UPF (Ultraviolet Protection Factor) is a newer rating for clothing, especially clothing designed for sun protection. It measures how much ultraviolet light penetrates the fabric. A UPF of 50 only allows 1/50 the amount of light through.
