Lightweight, temperature-regulating, and ridiculously comfortable, this is the base layer pant that makes synthetic long johns feel like a thing of the past.

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.
I initially bought 2 pairs for my son and I then went on to buy the 3 bundle as the price to too good to ignore. Such lovely socks to wear plus the colours are super cool and trendy that I actually look pretty good running to my mail box and back. great in the wash, no shrinking which is fab,
I have had my feet rebuilt after some crush injury’s
I have had my feet rebuilt after some crush injury’s, from a few years ago ,these socks keep them warm and make walking more comfortable, throughly recommend them
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.
Stretchy cuffs; shoulder "yoke correct" design; and sleeves handle being rouged up my arms
Beautifully stretchy cuffs; right fit to the shoulder "yoke correct" design; and sleeves handle being rouged up my arms.
During long marching on the flat; my arms get hot. I call it kangaroo heat.
I get my forearms (and shins) cool: and I'm good!
And: the colour is beautiful; shifts and changes in the light. I always feel ready for the next part of the march.
Just because you're two huts deep into the reserve: doesn't mean you can't look a proper gentleman.
