What Our Gearhead(R) Experts Are Saying: "I like having three jackets in one when I'm hiking in unpredictable weather. The Omni-Tech(TM) shell keeps rain out on wet days, and the sherpa liner is surprisingly warm on its own. Zipped together, it's a solid cold-weather setup. The adjustable hood and cuffs help dial in the fit when conditions change fast." When forecasts shift from drizzle to clear skies in a matter of hours, we rely on the Hikebound II Interchange Jacket from Columbia to keep pace. Built for hiking in variable conditions, this versatile system lets us adapt on the fly-wearing the shell alone in the rain, the liner on cool dry days, or both together when temperatures dip. The Omni-Tech(TM) waterproof-breathable shell with critical seam sealing keeps moisture out while allowing heat to escape. A drawcord-adjustable hood, adjustable cuffs, and droptail hem provide extra protection from wind and rain, while zippered hand pockets secure essentials. Inside, the soft sherpa liner adds cozy warmth and can be worn solo for everyday comfort. With its zip-in Interchange System, this jacket delivers flexible protection for changing trails and seasons.
