Smartwool Women's Merino 150 Baselayer Long Sleeve

The Classic Thermal Merino Base Layer Crew is the ultimate in men's hiking apparel. This versatile base layer is designed for both spring skiing and summer camping, thanks to the temperature-regulating properties of the Merino fabric, enhanced with Core Spun technology for increased durability. With a slim fit that showcases a slimming silhouette while offering unrestricted movement, this classic all-season Merino piece is perfect for 4-season layering and everyday comfort. The ultra-lightweight performance fabric blends Core Spun Tech to maximize durability with the thermoregulation and moisture-wicking power of Merino wool.

Thoughtful functional features keep you trekking comfortably, including a raglan sleeve design that eliminates seams for maximum comfort, and stretch merrow stitching that elevates comfort, range of motion, and fit. From the Hike Classic Edition Light Cushion Crew Socks to the Women's Classic Thermal Merino Base Layer 1/4 Zip and Bottom, our commitment to quality outdoor apparel extends across men's, women's, and kids' collections, with a focus on environmental sustainability, racial equity, and inclusivity.

The Women's Classic Thermal Merino Base Layer offers the same exceptional performance and comfort as the men's version. This 1/4 zip top features the same temperature-regulating Merino fabric, enhanced with Core Spun technology for durability. The slim, athletic fit provides a flattering silhouette while allowing for unrestricted movement. Pair it with the Women's Classic Thermal Merino Base Layer Bottom for a complete base layer system that keeps you warm, dry, and comfortable in any season.
