The quality is outstanding. Very cute style. So glad I gave in & ordered it. The weight will be very useable here in the PNW.
The mongrel is my first Iomerino purchase. I wanted a top I could wear mountain biking on those cooler days as well as running. I set out for a bike ride on a cold morning and it kept my temperature just right. As it warmed up the top was breathable and I didn’t get hot at all! Running in it is also a dream. I picked the green sleeves style, which looks so good. Blend in with nature. Very happy with it. Size wise, I’m glad I went small as I’d heard you are best to go bigger and almost got a medium. I’m an 8-10 usually for tops and small is perfect.
Looking forward to building up a collection of Iomerino clothing. Definitely worth it for comfort out there.
Love the pattern and style. Fits perfectly. It’s so warm & comfortable too. I wear beanies most days in winter so I will be living in this when it comes around again!
Excellent experience, purchasing and product.
Great fit and quality. Good to wear on a run or hike, and also as an every day top
Look, when I saw that there was an altitude zip mongrel in PINK I think I broke a land speed record adding it to my cart.
The altitude zip tops are by far and away my favourites for winter trail running - the zip allows for temp regulation and the thumb holes keep my hands nice and warm - helpful because I never seem to remember my gloves.
Its no coincidence I've rescued a baby magpie wearing this. The black and white stripes definitely made it feel safe.
Cannot recommend these highly enough - and I'll tell anyone that listens!
Slipped the track pants on - heaven to wear. So I bought 2 more pairs. Love them thanks.
This is my second mongrel, love them both, first with a zip. Both have a great fit, so comfy and warm for those chilly Melbourne mornings
Thought I had my walking gear all sorted, then they brought out the mongrel zip and I had to have one of each😜 Super comfy, perfect weight for crisp Melbourne mornings and I love the quirky colour combos...they have been in constant rotation since arriving.
Very comfortable. Breathes well. Love the loose fit.
This is my first mongrel and third ioMerino top. Love the zip feature, perfect for running in. Fit is true to size. Top is perfect for South Australian frosty mornings.
So comfortable, so warm, and they look good too!
May need to buy another pair or two.
Very comfortable, easy care they are great for working from home.
Well made extremely comfortable and does all the things the great fibre of wool is known for, keeps you warm , cool depending on the conditions and always comfortable
I love this top - i want every colour. Its so soft, and the sleeve length is perfect. Love!
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.
