Looking for an "ordinary shirt" that can keep up with all of your adventures? The year-round Merino 150 Base Layer Short Sleeve is up to the challenge. With Core Spun technology, Smartwool wrapped Merino around a nylon core for added durability while still keeping the comfort of ultra-soft, responsibly sourced Merino next to skin. And select colorways feature a more responsible plant-based-dye technique. Built for consistent comfort, even when wearing a pack, this shirt is ready to explore the world on your back.
This breathable, soft, lightweight fabric offers next-to-skin comfort, moves sweat away from the body, and acts as a versatile performance layer for warmer conditions.
