Description
The Merino 365 Men's Base Pant is the quiet MVP of your layering system. Designed to sit comfortably next to skin, it’s cut from 190gsm of superfine New Zealand merino for soft, breathable performance that adapts to whatever you throw at it—whether that’s alpine starts, long-haul flights, or everyday winter wear.
Merino wool naturally wicks away sweat, keeps you warm without overheating, and won’t hold odour—making these pants a solid repeat-wearer between washes.
Lightweight, temperature-regulating, and ridiculously comfortable, this is the base layer pant that makes synthetic long johns feel like a thing of the past.
Merino 365 gear is designed and tested by real outdoor people in Aotearoa, for real-world adventure. Layer up and wear it every single day of the year.
Fabric & Care
Fabric: 100% Merino Wool, 190gsm
Care: Machine wash cold on gentle or wool cycle with wool detergent. Lay flat or air dry.
Origin: Made in China or Fiji using NZ-grown merino
Why Merino 365?
Merino 365 was born in New Zealand and built for the outdoors. We use only premium, ethically sourced merino to create high-performance garments you can wear year-round—for sport, travel, or just staying warm every day.
We brought some of these to test out and have been so incredibly happy with our purchase.
These are the first socks to wear in gumboots that don't slip down and keep your feet lovely and warm.
I would recommend to everyone if you are on the fence just do it you won't regret it.
Excellent, cosy socks,
Excellent Service
Excellent price!!

The long-sleeved Merino shirt
The long-sleeved Merino base-layer (Iron Marle) is a great product for its ability to provide instant warmth & coziness when the weather is cool.It’s softness & roominess makes it ideal to wear alone or as a base layer under a sweater or coat when things get cold. I particularly appreciate its versatility in being able to be worn for sleep, lounging, or outdoor activities.It’s extremely comfortable & easy to wash.

I love these socks
I love these socks. My first set of three were purchased some years ago and I've worn them almost continuously every winter and they're as good as ever. I just bought my husband some so he can enjoy them too.
