If you’re looking to add a little extra fun to your next adventure, the Women’s Altitude ‘Mongrel’ is for you! Don’t let the name fool you, this is one seriously good Merino Wool Thermal Base Layer. 

Behind its colourful exterior, the Limited Edition Mongrel delivers the soft-touch comfort you’ve come to expect from our other Altitude Base Layers, as well as natural breathability, temperature regulation, moisture wicking and odour-resistance.

This Base Layer has flatlock stitching, raglan sleeves and is tag free to help eliminate chafe and maximize comfort. The drop back hem is designed for tucking into your outer layers, or sitting over bottom layers, with no exposed cold spots when you're on the go. The thumb loops keep your hands warm and stop your sleeves riding and bunching under your arms when layering. This Base Layer Thermal top is the perfect combination of performance, warmth and comfort with a little bit of fun thrown in for good measure.

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.

Perfect!

I have been drooling over the Mongrel tops for some time and finally bought myself one. It was everything I had hoped for! Not only is it really warm, it has a long body and sleeves which is perfect for tall, lanky me, AND it is so good looking!!! I am pretty sure I will end up buying more of them just so I can have one in every colour :)

I Keep getting more

Maybe I have 4 now.. but I know I love these the most. The fit is great the sleeves are long, the colours are just fab and you can wear it with jeans to the pub or under your snow jacket. And for that they Save room in your case when travelling for sure.

These are the coolest thermals I've ever brought

These are the coolest thermals I've ever brought. I've been living in Prague and for the last year in Glasgow and haven't found thermals anywhere near as trendy as this range to keep me warm through their snowy winters.

Oh so warm and fashionable

i wore the mongrel in the desert in Israel and felt comfortable wearing them around the campfire and they kept me nice at warm at night ...normally I feel the cold and knew they had done there job of keeping me warm when lots of others mentioned how cold they were at night!

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.
