I have been wearing my ioMerino t-shirt everyday for over 70 days on the Appalachian Trail thru-hike. It still looks and feels like new. I absolutely love it. It’s great fit, washes very well, doesn’t hold the hiker smell 😊, holds its shape even when wet, fast drying and most importantly super comfortable for any type of weather. Highly recommend. I might get the sleeveless shirt for the summer period as a second shirt.
I love my universal long sleeve tee. I have worn it on numerous long hikes and have found it to be fast drying if caught in light drizzle or when sweaty. On a cool day it is fine on its own, or under other clothes if cold. Perfect for when the weather is warmer too, plus protects arms from the sun. I love the dazzling blue colour too.
I’ve been wearing ioMerino since their launch and used to work in the wool apparel industry. Fantastic company and product- I still have base layers from 2008 that have worn incredibly… great ti see them evolving and improving. The performance aspect is excellent.
I am between sizes so went with the larger size and the fit is perfect. Very comfortable!
Have just ordered another pair in a different colour. These have fast become my favourite trackpants. I've worn these walking my dogs and they're warm but the fabric is so soft, light and breathable! Well done IOMerino! Awesome. I seriously don't want to take them off and they're stylish enough to wear out. Keen to try them on my next hike that's how much I love them!
This is fantastic for cold weather running. The zip is so handy for adjusting the warmth as I warm up. The neckline is cosy when starting out. I team this with an IO tank top and it works perfectly on a 1 degree morning!
The fabric in this singlet is incredibly soft. I like the cut too - good coverage (neckline, chest and length) if it’s cold but not too much. Highly recommend.
I have found the Ultra Trunks to be very soft, supportive and comfy. The sizing is accurate. Perfect for my bushwalks. I just about live in merino.
Very light & comfy for a curvy body. Soft & not itchy. Don’t ride up when walking.
I purchased my grey beanie to take to Mt Gambier for Generations in Jazz. It is going to be perfect for the chilly weather. Thanks friends at IO.
I've had a few ultra shirts, and loved them. These are less fitted, and are better every day shirts. I don't really see any reason to buy a different shirt ever again.
I usually buy another brand but thought I would give IoNerino a go. I certainly don't regret my decision. Perfect fit, perfect feel and quality. Will be buying another soon.
Works so well and keeps my old neck very warm
Love, love it
True to size. Comfortable, soft merino fabric. Holds size after gentle wash.
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.
