Omni-Shield Technology: This jacket features Columbia's Omni-Shield technology, which provides advanced water and stain repellency, keeping you dry and clean in various weather conditions by preventing liquids from absorbing into the fabric. Design and Features: It's a hooded jacket with a full-zip closure and a distinctive striped outer shell. The blue lining suggests it might be part of an "Interchange" system, allowing for the inner and outer layers to be worn together or separately, though this specific model is not explicitly identified as a 3-in-1. Purpose: Omni-Shield jackets are designed for outdoor activities and everyday wear, offering breathability and protection from the elements.
