Women's Woolverino Microweight Merino Wool Racerback Tank Top
Who says wool is just for cold weather? This ultralight racerback tank proves merino belongs in your summer rotation too. At just 113 grams, it's featherlight enough for beach days and peak-bagging, yet tough enough to handle your most rugged adventures thanks to Woolverino's core-spun construction. The wide racerback covers most sports bras while giving you full range of motion for yoga, running, or reaching for the next handhold. A drop hem adds extra coverage in back—because nobody wants to worry about their shirt riding up mid-workout.
Why You'll Love This Tank
At 84% Australian merino wool, this tank packs more wool than competitors like Duckworth (38%) while maintaining the durability of blends. The 17.5 micron fibers are finer than many premium brands, creating that soft, itch-free feel you can wear all day against your skin. The scoop neck flatters without plunging too deep, and flatlock seams prevent chafing during high-output activities. Whether you're layering under a flannel for cool mornings or wearing it solo on hot afternoon trails, this tank regulates your temperature naturally.
Why Core-Spun Merino?
Pure merino is soft but can wear thin with hard use. Woolverino's core-spun construction solves this: a nylon inner core provides strength, elasticity, and durability while the merino outer sheath delivers natural temperature regulation, moisture wicking, odor resistance, and UV protection. You get wool's benefits against your skin with synthetic durability where it counts. Triple certified OEKO-TEX, Woolmark, and Responsible Wool Standard for verified quality and ethical sourcing.
