Merino 24 Hour Long Sleeve Low Crew – Women's

Built for athletes who need one shirt to carry them from a multi-day trail push to the drive home, the 24 Hour Long Sleeve Low Crew is our top pick for active women who hate packing extra layers. Nineteen-and-a-half-micron Australian merino wool regulates temperature naturally and resists odor, so you stay fresh across back-to-back days without a wash. The curved hem and low crew neck work equally well as a standalone piece or a base layer.

• 100% 19.5-micron Australian merino wool — soft enough for next-to-skin wear, tough enough for multi-day use
• Natural temperature regulation keeps you comfortable from cool morning climbs to midday heat without synthetic help
• Inherent odor resistance lets you wear it day after day without that synthetic-shirt funk
• Curved hemline stays put during high-output movement and adds coverage when you layer over it
• Low crew neckline sits cleanly under a pack harness or jacket — no bunching, no bulk
