"What Our Gearhead® Experts Are Saying: ""This shirt’s a go-to when I don’t know where the day’s headed—morning jog, trail miles, travel. The merino blend breathes, moves, and never stinks, even when I wear it way too long."" The Roark Millcreek Merino Long-Sleeve Shirt is built for those of us who live in motion. Whether we're chasing singletrack, pounding pavement, or loading up for a cross-country loop, the Millcreek keeps us cool, dry, and ready for more. The blended knit of polyester, merino wool, and elastane gives us that perfect balance of next-to-skin softness, breathable warmth, and dynamic stretch. With articulated sleeves for fluid movement, a droptail hem for added coverage, and reflective branding to keep us seen when the light dips, the Millcreek is ready for whatever path we take—no matter how fast we’re moving."
