What would an Australian company know about cold weather?

I bought this shirt for a week camping adventure in the bush with no washing facilities. I put the no smell claim to the test and it didn’t disappoint. Wore this for 5 days in a row and no smell whatsoever. The fabric was lovely and comfy and not hot even in Australian summer. Loved this shirt!!

This is my first Celsius Tank, but I have bought a few other IO merino products. What I like: the soft feel, the fit, the quick delivery. It really has a remarkably soft feel, and I enjoy putting it one each time I wear it. I use it primarily for personal training, and I like the fit for this purpose. I found it 'true to size', ie the 'Large' size fitted me as I expected - close to my body, but not tight. On the website, the model chose a smaller size for a tighter fit. I chose not to, and it works for me. I received the item a day or two after I placed the order (and the website was well organised). I would appreciate more colour options, similar to the Altitude Zip I also bought. A classy product, and recommendable!

This is my second Altitude Zip. What I like: the soft feel, the fit, the high neck, a choice of colours, the quick delivery. It really has a remarkably soft feel, and I enjoy putting it one each time I wear it. I use it in combination with a roll neck jumper in cooler weather, and really appreciate the way the higher-than-average neck keeps me warm, and keeps the coarser wool of the jumper off my neck. I found it 'true to size', ie the 'Large' size fitted me as I expected. It was good to get some colour options, rather than black-or-nothing. I received the item a day or two after I placed the order (and the website was well organised). I can live without the thumb holes, but others will appreciate them, and they don't get in my way. A classy product, and recommendable!

If you want something soft and natural next to your skin that breathes, keeps you warm and is cool, then grab ioMerino's 'Mongrel'. I'm happy i did.

This is my 2nd top and I love it in summer and winter. It is so soft , fits well and good support for cycling. It has become my go-to crop even wear it around the house

Put these gloves thru some serious trailrunning. Absolutely love them. Keep your hands warm but don't sweat. A must have. I'll be buying more of these for sure.

This top is my new favourite! It does have all these benefits like being breathable and non-smelling etc. But what I love most is that is it just so darn comfy! Love it and would wear it every day if I could :)

I love this singlet! It is so lightweight and super soft. Hardly feels like you are wearing anything! And it is great for hot, sweaty hikes and runs. It really breathes. And as a bonus, doesn't smell!

I was able to purchase the Glacier Tracksuit Pants on sale. I half expected them to be similar to polar fleece pants in terms of warmth and softness. To my great surprise they are nothing like polar fleece. They are much more comfortable and soft without the bulk or static. And they keep me warm without overheating, which I often get with polar fleece. They are not inexpensive but they are so worth it.

I purchased two pair of the hiking socks because they were on sale. They are the most comfortable socks I now have. I have subsequently purchased five more pair. They are soft and keep my feet warm in the cold and do not overheat my feet at room temperatures. When, or if, these wear out I will be purchasing them again.

Great fit, super fine construction of the inner leg seam and hip/waistline. Comfortable and thermal. Aesthetic detailing on the lower leg is a nice touch. I love these leggings.

My fifth glacier tracksuit pant over the years. They’re simply perfect. Cozy, warm, stylish, gorgeous! I‘d never buy any other pant as long as they exist!

Bought as a gift. It's a lovely piece--tailored perfectly, great fabr8c feel, well-fitting. Need to get my own now.

Great length, fit, warm yet soft and light. The rose is a beautiful colour!

Super comfortable, easy to get on and off. Perfect for a small breasted woman. The blue is beautiful - I wear it showing under an low buttoned shirt, and it looks great. I'll definitely be buying more as the need arises.
