Flex Four-Way Stretch Merino Wool

Merino with a Little More Give. Perfect for high-output activities.

Merino wool is super soft, warm and comfy. But a little bit of stretch can make it that much better.

We created Flex Four-Way Stretch with the goal of making our merino wool hoodies and activewear even much more functional. From underwear to outerwear, Flex helps your Woolly move with you.

But it's not just for exercise. We love Flex in everyday life, like our Ultralight Long-Drop Boxer Briefs, and in the women's Short Sleeve Henley, for example.

Flex Four-Way Stretch is made with 95% Australian merino wool, and 5% Elastane. Keep all the benefits of merino, with just enough stretch.
