Columbia's Omni-Dry is the most breathable waterproof technology, designed to keep you dry during highly aerobic activity, whatever the weather. This extremely air permeable waterproof fabric transfers the moisture vapors you generate out of the garment at an extremely high rate, while still shedding the elements in the worst conditions. Omni-Dry is the ultimate in waterproof technology for the outdoors. During physical activity, increased body temperature can cause perspiration. In garments with low breathability, this results in condensation causing the wearer to feel damp, clammy or even wet. This is often mistaken for leaky or faulty construction, and is always uncomfortable. With Omni-Dry, air is able to circulate through the fabric, helping to regulate the conditions in the garment and keep excess moisture from collecting inside, while still maintaining its wind blocking properties.
This sun protection technology helps block damaging UV rays from reaching your skin, allowing for more carefree hours in the sun. Omni-Shade blocks Ultraviolet A and Ultraviolet B rays (UVA and UVB), helping to prevent sun burn and long term skin damage through tight weave construction, UV reflectors, and UV absorbing technology.
