Men's Merino Thermals & Underwear
Merino warmth for the everyday Kiwi man. Our men’s merino thermals and underwear are all about comfort, quality and warmth. Made from 100% merino wool sourced right here in New Zealand, these pieces from trusted local brands like Brass Monkeys and MKM Originals are warm, breathable, and built to last - whether you're up early on the farm, out in the elements, tackling the work day or just keeping cosy at home.
Merino Thermal and Underwear
NZ-Made Merino Thermals & Base Layers
Long days. Cold mornings. New Zealand’s changeable weather. That’s what merino wool was made for.
Our men’s thermal range is packed with year-round essentials: long sleeve tops, short sleeve tees, singlets, and thermal long johns – all made from superfine, breathable merino that traps warmth without feeling bulky.
They’re built to be layered - under your work shirt, under your jacket, or just under whatever you’re wearing that day - thanks to the natural temperature regulation of merino fibres. Whether you’re heading out early, clocking a full day outdoors, or taking it easy on the weekend, these thermals are designed to move with you and keep you warm without overheating.
What sets them apart? It’s the feel. That soft, itch-free comfort of merino against your skin. The lightweight construction that doesn’t bunch or cling. And the reliability of NZ-made brands that know what Kiwis actually need from a base layer.
We only stock what we’d wear ourselves. That means quality New Zealand brands like Brass Monkeys and MKM Originals - no cheap blends, no nonsense. Just reliable layers made from 100% merino wool grown right here on local farms.
Everyday Comfort Starts With Good Underwear
Underneath it all, our merino boxer shorts and briefs from Brass Monkeys deliver breathable, next-to-skin comfort with all the same benefits you’d expect from merino - moisture-wicking, odour-resistant, and soft enough to wear day in, day out.
