the magic of merino
Merino pulls moisture away from the skin, keeping you dry and warm on every adventure.
Your skin deserves the softest touch, and merino delivers without any itch.
Not too hot, not too cold - merino intuitively adapts, ensuring you stay comfy, cozy and cool.
Cause life. Our merino is machine washable and can be laid flat or tumbled to dry.
better adventures
The next-to-skin layer is the most important! Our merino will keep you dry, warm and comfortable making for better, longer adventures outdoors.
better for the planet
Merino comes from our wooly friends, the merino sheep. Unlike polyester/synthetic fabrics that end up in our landfills for hundreds of years (yikes), the adult long sleeve can be composted in six months.
