Merino Wool Thermals

Smitten makes the best merino base layers and thermal clothing

Skin-loving merino wool thermal base layers are your new best friend. Merino thermals are ideal for wearing beneath tops, pants, and jackets. 

Our machine-washable merino wool thermal leggings, underwear, pants, and more can be worn as sleepwear, exercise gear, underwear or outerwear. We make durable, smooth, comfortable pieces that can be layered for extra warmth. Choose from a range of weights and fabric blends for maximum comfort. Our heavyweight merino thermals are worn by many of the Tasmanian Police Search and Rescue Helicopter crew.

High-quality merino wool thermals will provide years of comfort and style

Smooth super-fine merino fabric has superb skin-feel and is completely breathable, helping you to regulate your temperature whether you're walking around town, jogging, hanging out at home or bushwalking. All of our hard-wearing clothes are made to a high standard and loved by active folk like mountain-bikers and hikers since they can be machine washed and worn again and again for years to come.

Quality merino wool thermals will save you money since they look amazing and last for years

Don't settle for boring thermals that only last a season. Colour your cold days with merino thermal base layers from the beautiful Smitten range – feel comfortable and look gorgeous at the same time.

Ethical wool, sourced from Tasmanian and other local producers – caring for animals and caring for you

All Smitten merino wool is sustainably grown using non-mulesed sheep from stunning Tasmania and other farms throughout Australia. The ultra-fine merino wool in our thermal clothing undergoes a thorough quality control process before it touches your body; cleaning and spinning, colouring, design, machining, construction and quality control. The end result is stunning sustainable, natural fibre garments that have been tested in all weather.

Smitten wool is a distinctive, super-soft fabric with incredible breathable, thermal properties, so you can wear the same garment in layers to keep you warm on cool days without bulk, and on its own in warm weather to give you breezy, comfortable style.

Merino wool is a beautiful, natural option for sensitive skins, with the convenience of being machine washable. Our products are sewn by talented women and sold by our proud family business.
