Like its name implies, the Columbia Sportswear Men's Big Raintech Jacket is built to do one thing really well: keep the rain out. But that's not all. Columbia updated the Raintech with Omni-Heat(R) thermal reflective, giving it a serious boost in cold-fighting horsepower. With our Omni-Tech(R) advanced repellency, full seam sealing, and a clean, simple approach to performance, this shell will shine in a wide variety of situations and weather conditions. Key details like Interchange compatibility, an adjustable hood and venting zips allow you the freedom to customize your kit. Great packability means you can easily stash the Raintech in your pack-just in case.
