Omni-Shade
Columbia's in-house name for its UV-blocking fabric treatment and construction. A label, not a specific rating.
Omni-Shade covers a family of Columbia technologies, and garments carrying it range from UPF 15 up to UPF 50. The badge alone therefore tells you the shirt was built with sun protection in mind, not how much protection it gives.
Columbia layers other names on top of it: Omni-Wick for moisture movement, Omni-Freeze Zero for the cooling dots that activate with sweat. They are marketing names for real features.
Read the specific product listing for the UPF number rather than trusting the family badge.
Every large outdoor brand has an equivalent naming system, and they all work the same way: a family name covering a range of implementations at different price points. The name tells you the garment was designed for sun; the rating tells you how well.
Where these branded systems do add something real is testing. A rating from a large brand has generally been measured to a standard, which is not always true of an unbranded listing claiming UPF 50+.
Look past the Omni-Shade label to the UPF number on the individual garment. Anything under 50+ is a step down.
