Need a tee that does it all and still looks good? The Womens Merino 150 Baselayer Short Sleeve from Smartwool works undercover as a baselayer on cool mornings or as a stand-alone piece during warmer temps. Featuring Core Spun technology, we’ve wrapped Merino around a nylon core for added durability while still keeping the temperature regulation and moisture management benefits of ultra-soft Merino next to skin. Raglan sleeves remove shoulder seams for comfort under a pack and smooth merrow stitching wraps from side to front for a flattering look.
