Meet your new favorite base layer—the one you'll reach for when temperatures drop and comfort matters most. We're calling it the Base Layer of the Season, and for good reason. This midweight essential pairs classic thermal functionality with sustainably sourced knit fabric that feels absolutely buttery-soft against your skin. Crafted from a stretchy organic cotton and modal blend, it delivers breathability when you need it and warmth when things get chilly. The four-way stretch means this high-performance crew moves with you, keeping you at just the right temperature whether you're layering up for a mountain hike or settling in for a cozy evening. Ribbed details at the neck and cuffs lock in heat while maintaining that impossibly soft feel.
