Going to buy 4-5 more of these … love these!

Lightweight, great for spring running

2 years ago
Really love the long sleeve shirt for long runs. Literally so lightweight it feels like nothing but still protects me from the wind, and light rain and insulates me just enough in the colder spring temps. I run hot when exercising so this is perfect for my body type. I have the Atomos Heather colour and it also is great for visibility in low light for safety. Only con was the looseness in the sleeves around the wrist. Not really sure why this is in the design but I would prefer the sleeves not to have as much movement when I am running.
Q: Pros:
A: Lightweight, bright, breathable
Q: Cons:
A: Loose sleves
Q: Activity
A: Running, hiking

Yes, I recommend this product.

Comfortable and effective light layer that I wear under a short sleeved technical running shirt. I do agree with other reviewers that the neck hangs slightly too low in the back.

Best Base Layer I've Found

2 years ago
I sweat a lot and am always looking for a highly breathable base layer. This is the best I've found. breathes well, drys fast and stands up to rough treatment. I use these for climbing and backcountry skiing.

Yes, I recommend this product.

Great fabric, but fit needs work

2 years ago
Incredible fabric in hot conditions, great colors, and top notch construction details. However, the pattern makers must have been asleep at the switch on this design. As Steve noted, the collar stands proud of the back of my neck as if the shirt was put on backwards. This is a major design flaw for a premium garment to be used in hot and sunny conditions (read: sunburned neck), and sadly means I'll probably end up donating this piece. The short sleeve version I have has the same issue, although it's less noticeable, probably due to the way the sleeves drape. Arcteryx: make these fit like your A2B tees but with this fabric and you'll have a winner. I'm 5'11" 145lb with lanky arms and the small fits fine in terms of length and chest, if not a touch baggy.
Q: Pros:
A: fabric, colors
Q: Cons:
A: fit
Q: Activity
A: hiking, trail running, mountain biking

No, I do not recommend this product.

Gorilla arms

I just received this shirt. I normally wear a a Medium in everything but the sizing info suggested a Small. The Small fits fine in the body but the sleeves come down to the end of my thumbs. I have never had a shirt with sleeves that long. Everything else about the shirt is great but I bought it to wear in the Summer, so nowhere to hide all that sleeve.
Q: Pros:
A: Body fit, material
Q: Cons:
A: Very long sleeves
Q: Activity
A: Runnung & hiking

Yes, I recommend this product.

The best LS you can buy

3 years ago
I’ve been waiting for this. A LS version of the incredible short sleeve cormac without any giant logo or text. I wear a technical LS every day, all year. Patagonia, lululemon, and plenty of others are up there high on my list. But this shirt is the new king. Just like the short sleeve version, it’s just perfect for every day use and high output activities. Pair it with a proton vest and it’s unstoppable across a huge temp range. The neck issue referenced in another review must be a one off issue as I’ve not had that issue. Phenomenal piece per usual with arc. I’ll be buying as many colors as they offer. I’m 6’2, 165lbs and bought a medium. Perfect fit.
Q: Pros:
A: Fabric, fit, sleeve length
Q: Cons:
A: Not enough colors!
Q: Activity
A: Daily wear, hiking, running

Yes, I recommend this product.

I had the same neck issue and returned the two shirts I bought. The neck collar is boxy. It looks funny if you're paying attention. you might not otherwise notice. The shirt is terrific otherwise.

Disappointing

3 years ago
Not sure the neck patterning is correct on this item as the back of the collar on me is very baggy, so much so that it hangs back away from my neck which spoils the overall look and comfort. I'm also not liking the strong smell that this shirt gives off due to being washed in a biocide, I'm sure this will dissipate over time, but that collar I just can't live with.
Q: Pros:
A: Arcteryx quality
Q: Cons:
A: Baggy collar, and strong smell.
Q: Activity
A: Summer pursuits.

No, I do not recommend this product.
