Columbia Men's Baselayer Midweight Long Sleeve Top AM6944 F11

The best way to bundle up for the backcountry is to pile everything on like a layer cake and then peel it off piece by piece once the sun starts to thaw your frozen world. The perfect cozy baselayer, this midweight thermal long sleeve is this super-soft and Omni-Heat® armed. Its Omni-Heat thermal reflective lining uses space blanket technology to trap your body heat without adding bulk, yet still retaining supreme breathability for times when your heart rate hits the red zone. The Midweight Long Sleeve is also durable, and anti pilling, and it fits close to the body for easy layer-ability.
