Merino Undergarments
Shop men's merino thermals and undergarments made in New Zealand. Our range features Brass Monkey Merino thermal tops, long johns and boxers, Supreme Merino singlets, V neck vests, crew neck tops and long johns, and Tussock Ridge merino tees.
Merino base layers are the foundation of staying warm. Worn next to the skin, merino wicks moisture away from the body, holds warmth even when damp and breathes when you are working hard. It also resists odour, so a merino thermal top can be worn for multiple days on a hunting trip, ski holiday or long shift outdoors. Compared with synthetic thermals, merino is softer, less likely to hold smells and more comfortable across a wider range of temperatures.
Build your layers to suit your day. A merino singlet or short sleeve V neck vest sits discreetly under a work shirt. Long sleeve crew neck thermal tops and long johns are essential for cold mornings, farm work, fishing and the snow. Merino boxers offer breathable everyday comfort. Base layers should fit close to the body without restricting movement, so check chest and waist measurements in the size guide. Machine wash on a gentle wool cycle, skip the fabric softener and dryer, and your men's merino thermals will last for many seasons.
