An all-season favorite, the Merino 150 Long Sleeve can be sported as a base layer in the fall or summer when it's time to go backpacking. This base layer features Core Spun technology—which features Merino wrapped around a nylon core for added durability while still keeping the comfort of ultra-soft, responsibly sourced Merino next to skin. Our Raglan sleeves eliminate shoulder seams for perfect comfort under a pack, and smooth merrow stitching wraps from side to front to keep you looking as good as you feel.
The Smartwool story started with the belief that feet should be comfortable, no matter the adventure. One simple pair of Merino socks challenged the conventional wisdom and the way outdoor enthusiasts looked at their feet. It's not just about the Merino, though. It's what Smartwool does with it that makes them different. For over 20 years, they've been pushing the boundaries of Merino to create smarter, more capable products from head to toe.
