Q: How should I care for my merino wool base layers?

A: Merino wool base layers are easy to care for. Wash them on a gentle cycle with cold water and lay them flat to dry. Avoid using bleach or fabric softeners, as these can damage the fibres. Proper care ensures your merino wool base layer stays durable, breathable, and naturally odour-resistant for longer.
Q: What should I wear over a Merino wool base layer?

A: What you wear over your merino wool base layer depends on the weather conditions. For a warm day, consider a lightweight, breathable mid layer such as an icebreaker merino wool sweater. For colder conditions, add a fleece layer for extra warmth and insulation. For outer protection, choose a weather-resistant jacket that guards against wind and rain while maintaining breathability.
