The Columbia Boom Runner II Jacket is a fully featured and classically designed weatherproof shell that uses Columbia's own exceptional fabric technology to deliver all-mountain performance and protection.
| Omni-Tech™: | Omni-Tech's first layer of defence is Omni-Shield™, which prevents most water from ever making contact with the inner layers. Next, a microporous membrane provides the primary impervious layer of defence by completely blocking the passage of water molecules into the fabric. Omni-Tech membranes are 100% air permeable, which allows moisture vapours to escape. This superior breathability keeps you dry from the inside out. Lastly, lining materials protect the Omni-Tech membrane from underneath, while adding additional wicking properties. |
| Omni-Shield™: | This water and stain barrier resists light rain and stains, keeping you clean and protected. |
| Omni-Heat™ | Columbia’s thermal reflective lining technology helps regulate your temperature by reflecting and retaining the warmth your body generates. Little silver dots reflect your body heat back to you to make Omni-Heat 20% warmer than an ordinary lining, while space between the dots allows heat and moisture vapour to escape for maximum breathability. Silver dots + breathability = thermal regulation. |
| Wicking: | The act of transferring moisture from the skin to the outer layer of a garment quickly and efficiently, where it evaporates. Provides a drier more comfortable environment inside a piece of clothing/equipment. |
| Fully Seam Sealed: | Every single seam is taped with a high quality waterproof band. |
