Customer Reviews Arc'teryx Ionia Merino Wool SS

Fits to size comfortable across temperatures and durable

This is my everyday go to shirt (work, school, weekend, hike, climb, etc.) Great quality that almost makes it worth the cost. Great odor elimination, soft feel, good stitching, well cut.

Love the soft fabric and fit. The longer sleeves are great. Most other merino shirts have sleeves too short. My new favorite merino short sleeve shirt.

Great shirt, warm when needed and airy when needed

Incredibly soft and comfortable. Fit and construction are very good. Has worked great to work out, hike and do basically whatever in. Cost is a little steep but you in this case you're getting what you pay for.

I couldn't be happier with my purchase! The fabric is top-notch and the fit is spot-on. The design is true to the images, and the craftsmanship is superb. This item has quickly become a favorite in my wardrobe. I'll certainly be shopping here again!

Great fit, soft feel and quality materials, construction and design

6 foot 2 and 90kg and bought a medium and large but opted for the large. If you prefer a tighter fit go for the medium. Material is great and would purchase from Merino range again. T shirts are very long, not something that should put you but something that should be reviewed going forward.

90%+ of my wardrobe is merino wool and my first impression is this shirt is not at all what I was expecting. The fabric has a much more technical feel and in fact if it were not listed in the product materials, I would be hard pressed to guess this was almost 90% merino wool. That said this is an amazingly comfortable shirt both in the fabric and the fit. Some Arc'teryx shirts have a very odd high/tight neckline which makes them borderline unwearable but this blessedly does not suffer from the same design. Arc'teryx has (used to?) an edge/seamless trail running t-shirt that may just be the most comfortable t-shirt in the world (it is for me) and this runs a very close second.

I bought this shirt online a month ago, it is my new favourite workout shirt. This shirt is super comfortable and it fits perfectly.

I bought several of these shirts, when I found that the first shirt I bought kept me cool in the summer heat. Hope to get many summers of use out of theses shirts. The only thing that I would nit pic I have wide shoulders and the shirt fits great but IMO shirts are a little long in the body. But I can live with that.

Like always, top quality when it comes to the workmanship and materials. Especially the merino wool is great when you doing intense activities a longer period of time because it provide you functional temperature handling and block the smell production.Just be aware that merino wool is not the most durable material when it comes to rock and plant contact

Soft and fine texture. Well ventilated. Worry free of sweating odor! Very nice product!

Love the material, colors and fit. It is a good idea to review the washing instructions

I love how it hides sweat, wicks, and dries quickly. Can be worn casually, but still put in effort for mid-intensity effort

These are my best undershirts. The thermoregulating, anti odor, and wicking properties of this weight of merino wool make it perfect for the summer. I do prefer the midweight Leaf version of this shirt in the fall and winter, but that can get a bit steamy in the summer. These are a lot thinner than the Leaf and pill a bit easier, so I don't use these with heavy packs or other activities where abrasion can rip up a shirt like this. I will grab my sun hoody that can handle being put through the wringer. These shirts are for chilling. You do have to baby these more and follow the instructions on the tag. I've found that a top loader's churn can be too rough on these, so I hand wash them at the end of the week by soaking them in a bucket and hang drying. They're more of a casual, everyday shirt that feel silky, provide all day comfort, and still give you all the performance fabric benefits of merino wool. If that's the use case you're looking for, these are perfect for you.

Wow!! What an amazing surprise, love the texture and fit....

Very comfortable, doesn't smell after wearing it all day. I sized up being 6'2, 225lb with broad shoulders/chest. Could've done a XL but wanted more room since I'm mainly wearing it in the summer

I did some backpacking this weekend wearing this shirt. It has an amazing texture and regulates heat perfectly. Love the feel and the fitted style

I was looking for a clean design without big logo or print. This shirt delivered exactly what I want. The fabric is super comfortable. It keeps you dry and cool when it's hot and warm when it's chilly. A huge advantage over Polyester shirts is the fact that you can wear it several times without becoming smelly.

My favorite shirt I have ever owned is an Arc'teryx black athletic t shirt. I lost it and tried to re-order the same one. I must have ordered the wrong one because the shape, fit, and design are all the same but the material was not what I was looking for. Id like to order a new one soon and hopefully it will be the correct material. I also own the long sleeve version of my favorite shirt but was attempting to order the short sleeve, solid black, Arc'teryx shirt.

Trs bon produit, voir sur le long terme. Prix lgrement survalu pour un t-shirt mme en laine mrinos, d'o l'toile manquante.

I just bought this shirt to workout. Its very comfortable but idk why they would make the sleeves so long. It actually makes no sense. Its crazy how difficult it is to find a quality workout short nowadays tight on the arms loose on the chest. I am 26 6'1 190lbs been working out my whole life. the sleeves need to be about 4 inches shorter. Crazy how many brands i buy and return. Id pay a lot for just a good shirt man. I will be returning my large shirt

Tried it on. Ordered large which is my normal size. Fits well in torso and shoulders but the collar is high in front and cuts across my throat and is low on the back of my neck. Yes, I had it on right, logo in front, but feels backwards. Can't imagine others won't have similar issues. Uncomfortable in front, more bare uninsulated skin in back than there should be. I really respect Arc'teryx and have one of their older merino t shirts that is wonderful. But this is not, and it costs more than most similar products from competitors. I Expect better from them.
