Omni-Dry Technology
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 is achievable because the Omni-Dry membrane is highly air permeable (100cc/minute vs. 0cc/minute for Gore-Tex) and extremely thin and lightweight (7 grams per yard vs. 40 grams per yard in Gore-Tex.
