I/O Bio Merino

I/O Bio Merino is the absolute softest merino available. One touch and you understand the difference.

Yarn is the most critical element in building functional fabrics with next-to-skin comfort, long lasting wear, and superior washability. Our attention to yarn is what sets I/O Bio Merino apart from every other merino brand. We spin our own custom crafted yarns, giving our garments the best quality and consistency possible.

Since 1870, our parent company, Michell, has been sourcing the finest merino fibers from around the globe. They pioneered the cleaning and processing techniques that result in the softest merino fibers while continuously supporting sustainable practices at all levels of the supply chain.

I/O Bio Merino is the only merino brand to quality control the entire process from raw fiber to finished garment. Our superior yarn is the most critical element in building functional fabrics with next-to-skin comfort, long lasting wear and superior washability. Our in house expertise is what sets I/O apart from every other merino brand. We spin our own “low-torque” yarn, which gives our garments a better handle, quality and consistency that stock yarns cannot match. This is why I/O Bio Merino is the absolute softest merino available.

The particular function of each I/O garment is closely linked to the type of fabric used. We have created a range of fabrics never before seen in merino, each of which is suited for specialized use. From lightweight ribs to heavy fleece each fabric gives our pieces a unique function and style. From sourcing the world’s finest natural fibers, to the engineering of new fabric constructions, I/O offers the softest merino available from start to finish.
