JMNZ Merino

Climate control for your body

Merino wool has the natural ability to insulate air - warm and cold.

Yes, cooling too! Wool is an active fiber, even after any processing wool is still able to react to the body’s temperature.

During warmer seasons, although our woolly friends need to be sheared, before this time comes, their ‘wool transfer of moisture’ ability performs at its peak, transferring moisture from the skin to the surface of the wool, which evaporates naturally allowing the body to breathe. Cool aye?

 In cooler months, layering merino will trap air between garments increasing insulation and retaining warmth. It also has additional warming properties as it can absorb up to 30% of its own weight in moisture, drawing it away from the skin, retaining its own natural warmth and your body’s too, even while wet! That’s hot! All the while it provides breathable, comfortable wear.

Sourced from

The majority of our Merino is sourced from Levin, in the Manawatu region of New Zealand, where it is knitted and every roll of fabric highly scrutinised before it even reaches us! (By the way the scrutiny doesn’t stop there - we pride ourselves in our quality control!)

 Occasionally our merino is mixed with wool from Australia before it is spun. Although merely supplementing what is naturally ours!


Merino is in a ‘weight of its own’! – meaning there are so many choices and weights available. 

GSM = the grams per square metre. It’s the metric measurement of the weight of a fabric. Fabric weight is commonly a definition of the thickness of the garment, but sometimes they can be bulky to wear!

‘What’s a good weight to buy you ask?’ – Well a lot of winter hoodies, sweatshirts can be 300-400gsm, don’t forget, but bulky too.

Merino offers the same benefits, for all year round wear at just 220gsm! That’s what we use on our garments, and even lighter at just 170gsm for our merino accessories. Now we think that’s warming to know!

How soft

Common wool can itch but not Merino with its ultra-fine fiber and elasticity it maneuvers easily with your body’s movements allowing for a softer feel against the skin.

Fact There is a measurement for Merino softness which is called Micron. This is used to class the wool by measuring the diameter of the wool fiber, starting from 18 microns being the finest, to common wool ranging from 25-40 microns. Our Merino varies but generally no more than 20.5 micron – now that’s soft!

Easy care odour free wear

With Merino’s natural allowance for body climate control it supports days of odor free wear, it also has its own natural protective outer making it stain resistant – that means less washing!

Fact – One company was asked to develop a merino garment for the army that would need to be used unwashed for 138 days! We recommend if you want to keep your friends you wash your merino a little more frequently!

The flow of air through the wool fibers allows for moisture to be released preventing build-up of bacteria that causes odour.

In - Fact – Merino fibers have several natural anti-bacterial properties!

Supporting all of this Merino has its own anti-static properties that help to repel dust and lint…how fantastic is that?

Merino can be machine washed with other garments but tumble drying is definitely not recommended but do you know what, Merino’s natural insulating and breathable qualities allow it to air dry quicker than other garments too.

With its smaller flexible fiber giving it natural elasticity it has amazing anti-wrinkle qualities, the fibers elasticity immediately bounces back into place. Yay no ironing!
