KNOW YOUR TECH breaks down the scientific technology used in your favorite sneakers and activewear. Let’s demystify your next purchase: today’s technology is Columbia Omni-Wind Block. Part of the brand's all-encompassing Omni tech, Omni-Wind Block is designed to protect against one of the environment's most unpredictable forces. Fall and winter temperatures can be cold enough, but with added windchill, the cold can become nearly unbearable. Columbia Omni-Wind Block technology helps to ensure that wind doesn't enter your garment while remaining lightweight and breathable.

What is it? Columbia Omni-Wind Block is designed to protect against nature's harsh, invisible wind. Compared to standard fleece and other wind blocking styles, Omni-Wind Block prevents any wind from entering the jacket whatsoever. Many Columbia Omni-Wind Block styles are enhanced with a breathable membrane that allows perspiration to escape while maintaining a strong barrier against the wind.

How does it work? Columbia Omni-Wind Block is built with a durable waterproof fabric that shields against harsh winds. It also features a breathable membrane so any moisture accumulation can easily escape while remaining protected from outer wind and water. The result is a warm, dry, and comfortable feel.
