Shiftup Half-Zip Fleece Hooded Jacket - Men's

You wonder if the tendons in your knee look similar to a mountain bike's chain shifting up gears anytime you're trail running up steep terrain. One thing's for sure, your knees would certainly be shaking in the frigid cold if you weren't sprinting, and the Outdoor Research Men's Shiftup Half-Zip Fleece Hooded Jacket is keeping your core plenty warm, so you're set for miles of shifting those tendons up, down, and all around your knee. Its Hexagonal Fleece is remarkably excellent at wicking moisture, drying quickly, and breathing for running-specific comfort.
