Wow!

I read the reviews before I purchased these track pants and now that I have them, agree with the general view of most people who cant believe how great they feel to wear. SO comfy and easy to slip on with anything you like on top. Smart enough to wear out or for yoga, exercise of any type or just to relax in at home. Everybody’s covid go to!, Some other colours would be good- navy, tan?..

Lovely design

I really like the asymmetric design, something I haven't seen before in similar products. Would be nice to have an option to buy same top in bit thicker fabric as well, that's why only 4 stars, but otherwise it's perfect.

Perfect little, snuggly compact warm me up on a cold morning in home outerwear

I love the hood which covers most of my face comfortably and is a big boon or my bald head! It is so soft!
This piece is going traveling with me as the outerwear on planes. Also love the long sleeves and thumb hole for keeping hands warm.

Perfect for summer

So soft and comfortable for summer runs

Tracksuit pants

Wry happy with purchase

Smaller than size guide suggested

Hi there
I can't speak to the quality of the product as it came nowhere near to fitting (despite using the size guide)
I have regifted it to someone who hopefully will get some good use out if it (I chose not to return because I did find someone who it fitted)

Love the stripes!

A large is what I purchased because in all merino companies I've ordered from, the large is usually best for me. (5'8"-135#). Your large is a bit snugger and actually fits even better than the other companies large sizes. I'm 100% happy and hope to order more from you in the future.

So comfortable

I have been wearing IoMerino for probably 15 years now, even going way when it IO BIO. The quality is top notch, and softer and better then the other top competitors. Unfortunately there isn't a Canadian distributor anymore, but that didn't stop me from still purchasing online and shipping here to Vancouver, Sizing is true .with the duty and taxes its a little more, but well worth it my opinion. The Altitude Zip is my favorite, it hugs the body so well, and regulates the heat, and colors are vibrant. During my winter rides when its down to 5c I wear the altitude, pinnacle Zip, and altitude neck tub with a high Vis wind stopping and its perfect. Overall I love the product line, and have many different pieces! The customer support is fantastic as well!

super comfy

The best thing I own

It's warm but not too warm, never gets stinky even though I wash it maybe once a month. Fits great... nice and thin. Plus it has a hood when things get cold & windy at Mammoth Mountain and it fits under the helmet nicely. Can't say enough good things about the altitude hooded zip.

Best trackies ever.

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.

Compression leggings

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!

HIKING SOCKS

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

Mixed review in the NorCal

I primarily wear tights to help support a knee issue, plus the benefits of compression are real, most of my tights are spandex / lycra (shiny) or polyamide / elastane which is cloth-like.
I needed something warmer, but not "long-john's" because I don't wear baggies or shorts over them. I use an inner comp short. Finished Wool tights for guys are hard to find.. most are made like underwear.
Be very carefully putting these on, I tore mine in the calf area, however I was able to repair it.
Since we are having a mild winter, I have had these out for my morning 6 mile trail runs in 33 - 37 degrees and felt comfortable in them. They handle the sweat by pulling it away and evaporating, even better than my polyamide Ruhn tights and it doesn’t soak it up like spandex or lycra. I recently ran them 25 miles in the forest with a temp range of 35 - 50 and I hardly noticed they were there. Did not have to adjust or pull them up, they just become part of you. Compression is just right, not rubber band like 2XU, and not flat like UA. For hard climbs and steep descents and everything in between I was impressed with the fit and performance.
My issues are:
The waist band - Even though it wasn't a real problem, it just doesn't look finished, it should look like outer-wear.
No pockets- An outside patch pocket or inner key pocket would be great.
Overall:
My goal was warmth and compression and these IO hit the mark. Aside from minor details, they are great performance wear for a relatively light garment.
I am a lot rougher on my other tights and never had a tear or problem, so the durability is in question. Since there is little or no competition in this category: Mens Wool compression tights, Im inclined to give them 5 stars.

New for old

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.

Comfortable & odourless

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.

Go for large if you have long hair.

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.

Quality under-layer.

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.

Summer cycling

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.

Excellent undies

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.

Another great mongrel!

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

Lightweight tank

A good lightweight tank that is super soft. Slightly on the see-trough side when wearing dark colours underneath and under the arm is a little low for my liking. Overall, though this is a good summer tank to wear on hot and humid runs.

Comfortable casual polo

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.

So comfy and no smell

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!!

Celsius tank - Recommendable

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!

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.
