Universal long sleeve

This was my first merino wool shirt, I'm about 5"9 and 75kg and size large fits me good, before I ramble on too much I'll just say it's awesome and has become my go-to shirt and would definitely recommend it, it's great at regulating body temp and keeping you warm. I wear it under an Arcteryx atom Lt when cold and just by itself when mild.
It was hard to know what to expect in regards to the feel of merino wool having not worn other shirts before and I suppose it would vary person to person considering everyone's skin is different. For me when first put on for the first minute or so there's a slight scratchy feel to it ( not itchy ) then it's as if my skin adjusts to the wool and it's just like wearing a normal shirt.
I have since bought two merino shirts on sale at Kathmandu I knew the quality wouldnt be as good but I was willing to gamble and see for myself.
The Kathmandu shirts to me are itchy and stay that way throughout the day, it's bearable but definitely not comfortable and aren't even in the same league as the Io merino shirt.
I'll round up by saying you usually get what you pay for and for my next shirt I'll definitely be buying another one from here.
Cheers.

Fabric Guide

While Merino is an amazing natural fibre, not all Merino fabrics are created equal. At ioMerino, we make our own fabrics, using only the best quality fibres, and to very specific specifications that make the most of the natural benefits of Merino. All of them are 'Merino rich’. No cheap blends passed off as Merino. No cheaper scratchy fibres or synthetic substitutes to save money. No unethical production. And each fabric is made for a specific purpose. So if you see something with a small amount of elastase or nylon added, you can be sure it absolutely needs to be there to enhance the natural stretch and durability. 

It took every bit of our 140 years of experience in the wool industry to perfect our fabrics, but we think you’ll agree the end result was more than worth the effort.

Ethically Made. Ethically Sourced. Perfectly Natural.
