Love!!

This is my first purchase from ioMerino. I went with bust size since that’s the biggest part of me (!!) regardless of other measurements. Perfect fit.
Comfy. Warm. Fun.
Hit the trails in winter = worth every cent!

Thank you for the review! Enjoy the trails this winter in your new Mongrel! Their limited edition, so you're one of the few that has this design.

Soft and cute top

This is my first ioMerino purchase and I am quite happy with it. I am a size Small and ordered a size Medium because I like my running top a tad loose. It is pretty long at the body which I don't mind, but it does gape a bit at the neck. I think size Smal would have worked as well. I like how soft the fabric feels against my body and I like how unique and cute the pattern is. I wear it as a baselayer, as well as a running top. It works great for both. The thumbholes are fabulous. If I can be picky, I wish the ioMerino logo were printed on instead of sewed on. All in all, a great top and it makes me happy to wear it. I will get more Mongrel for sure when more cute ones are available. I would love to see some tops with yellow color.
Over the years, I have worn merino clothes from various companies, ioMerino is definitely one of the best in terms of softness and comfort.

Coolest hikingshirt ever

Hi ioMerino, I absolutely love the mongrel-shirt. Is fits perfectly, the wool is amazingly soft to wear. It’s my favorite shirt. Too bad it is so expensive to buy from the Netherlands, but if you should open a store in the EU I will be the first in line for more shirts.

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.
