Wool Designed for Athletes.

Woolverino’s core spun technology allows for merino wool garments which are durable, high performing, and suitable for your high-intensity activities. Our blend of merino, nylon, and spandex creates a well-fitted garment that moves with you, cooling you down when it’s hot, and warming you up when it cools down. Woolverino is ideal for athletes, runners, cyclists, and hikers alike.

Woolverino Core Spun Merino Blend Yarn

Core Spun Technology.

Nylon inner core provides extra strength and resiliency, as well as extra elasticity which help achieve a tighter, athletic fit to the body. Merino wool outer sheath keeps insulation, moisture wicking, and UV protective properties next to the skin so you can still reap all the benefits of merino wool.
