We choose our materials intentionally.

We strongly believe in natural fibers, and we seek out the best possible materials and fabric technologies. Sustainability is a key part of our promise to you. We use as much Merino wool as possible, and we use all natural, renewable, biodegradable fabric and materials whenever possible.

We use synthetic materials sparingly and thoughtfully to boost the performance of some of our products and help them last longer. Creating longer-lasting products is one way we tread more lightly on the planet. Everything we make is free of harmful chemicals, meaning it's good for you and for the environment.

Merino Wool

Most of our products are made mostly or entirely of Merino wool: a natural, renewable and biodegradable fiber produced from the Merino breed of sheep. The sheep eat grass, drink water and take in the sunshine—all essential ingredients to creating soft, comfortable Merino wool fibers. We only use wool from non-mulesed sheep, and 100% of our wool is sustainably sourced from certified humane sheep farmers in Australia and New Zealand.

Merino wool is naturally odor resistant, moisture wicking, breathable, temperature regulating, sun protective and quick drying. Merino wool fibers are super soft next to skin.

Corespun (m)Force Technology

Our (m)Force™ Nylon Core Technology enables us to make lightweight yet durable fabric with a high Merino wool content. Super soft Merino wool is wrapped around a continuous recycled nylon filament to create a fabric that is stronger, better able to hold its shape, faster to dry and more long-lasting than 100% Merino wool at similar weights. Plus we love that this technology puts Merino wool next to skin.

Axio

Axio™ is one of our newest fabric innovations. This patented Japanese yarn spinning technique allows us to create our thinnest high-Merino content fabric yet: 135 GSM with 84% Merino wool. It's ultralight yet still durable, stretchy, and resistant to pilling, shrinking and wearing out after many washes. This technique spins a polyester filament in a spiral with soft Merino wool to make the wool stronger and lighter.

Grid Fleece

Grid fleece has long been trusted for warmth without bulk, and our new high-Merino content grid fleece takes it even further. Our innovative wool grid fleece fabrics have Merino wool on the interior next to skin with a more durable Merino-blend exterior for the Wool Grid Fleece and a quick drying recycled polyester exterior for the LT Grid Fleece. This fabric has the best of both worlds—synthetics and natural fibers—strategically knit so you get all the benefits of having natural fibers against your skin.

Tencel

Keeping in line with our commitment to natural, sustainable fibers and practices, TENCEL™ Lyocell is a great addition to our product line. It's made from renewable wood pulp in an ecological closed loop process, meaning there's very little byproduct from production, and less land and water are used.

The smooth, silky fibers of Tencel are softer than silk and cooler than linen, so it's a great complement to Merino wool's natural temperature regulation and technical performance. Both Merino and Tencel are more absorbent than cotton and boast antibacterial properties that reduce odor retention.
