What Our Gearhead(R) Experts Are Saying:"The Columbia Switchback IV Jacket has lived in the bottom of my daypack for the better part of two seasons now, and it has bailed me out more times than I can count. It packs into its own hand pocket so it takes up almost no space, and the Omni-Shield treatment does a solid job turning away light rain until the sky clears back up."The forecast said partly cloudy, but the sky had other plans. That's exactly the scenario the Columbia Switchback IV Jacket was made for, the kind of day where the weather shifts faster than your itinerary does. Columbia built this shell to live in your bag without you noticing it until the moment you actually need it, at which point you'll be very glad it's there. The 100% nylon shell carries Omni-Shield moisture and stain repellency, turning away light rain and trail splatter before it soaks through. The attached adjustable hood cinches down when things get serious and stows away cleanly when they don't. Adjustable cuffs and a drawcord hem let you seal out the wind and dial in coverage on the fly, while the zippered hand pockets keep your essentials dry and accessible. When the clouds break, the whole jacket stuffs back into its own hand pocket, compact enough to forget about until the next time the sky gets moody.
