New York Times recommend Merino

I'm onto my fifth pair of these amazing track pants. I slouch around the house in the old ones that now have a few marks and holes. Newer ones I've used in around the world travels. Best garment on a long haul flight (remember those?). More comfy than leggings, warm and soft. Easy to care for, as with other ioMerino garments I put them in my front-loading washing machine on the wool cycle and use TriNature gentle washing liquid. I've used the same formula for years and I find they keep their shape and condition. I think I'm going to put the oldest pair in my compost heap where they can return to the Earth. Lovely. I unreservedly recommend these.

I LOVE!!!! these leggings and live in them. They feel great and make me feel strong and athletic. The only improvement I would like to see is for a side pocket so I can carry my mobile phone around as I like living in them and can't bare to be separated from my phone either!

LOVE THEM. FUZZY, WARM AND JUST PERFECT. GREAT CUSTOMER SERVICE. ALL FIVE STAR!!!

Universal really says it all for these T's. Worn as a single layer in warmer times and as part of my iO layering when the weather gets cold they really are my travelling all rounders.

Seamless stitching & pattern design make this t 'feel' good on, then there's the perspiration quickly dries off once movement stops, with no residue or that dried perspiration feel, & no whif of body odour whatsoever, just like i put it on. Good shirt.

So thin and light weight. Adds no weight at all to compulsory trail running gear. I usually have trouble getting these kind of beanies to stay put (they usually ride up with my long hair), but the size large seems to stay put and just covers the tops of my ears.

Very close fitting as described - Think body hugging! I am a size 16 and purchased an XL. If I wanted it as an outer layer, I would have gone for an XXL. Good quality and feel, and one of the few tops I can find with a Raglan Sleeve - Please give me more with Raglan sleeves - so much more comfortable on the move! Also, great customer service.

Purchased as a gift for my partner who was looking for a long sleeve light merino top with a collar for sun protection when cycling. The blue colour is great and the large size is a good relaxed fit, not too tight but not too baggy. He wore it on a 3 day bike tour without washing, I didn't notice any smell. It will be able to be used also for a number of activities like hiking and ski touring.

Top quality undies. They are thoughtfully designed for the male body which makes them very comfortable to wear. Nothing is too tight or too loose on these underpants.

Great fit! Great style! What’s not to love! It’s the shirt I reach for every day. Love the new colour! 😊

A comfortable polo that is a little dressier than other ioMerino shirts. I was expecting a more traditional polo texture, but the texture is the same as other ioMerino shirts. As a short person, I would prefer not to have the drop hem at the back, because I don't really need the extra length. A good travel polo. Would like to see in some additional, lighter colours.

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.
