Here's what others have to say...


Great athletic shirt

  • Familiarity:I've used it several times
  • Fit:True to size
  • Height: 6'1"
    Weight: 180 lbs
    Size Purchased: Medium

Worn this shirt hiking and in the gym. It is a trim fit. As mentioned before the sleeves are a little longer than my other Arcteryx shirts but that's a plus on the trails. Plan on taking this one with me on the CT.
Very light weight but not a compression type. Excellent shirt from Arcteryx!


Versatile all around Tech Shirt

  • Familiarity:I've put it through the wringer
  • Fit:Runs small

Its the type of shirt that works great at the gym to running outdoors to indoor rock climbing and more.

I love the fit of the shirt. It is quite a trim fit made with a 4 way stretch fabric that is a bit more burly than most. The shoulder gussets hug your traps and the semi raglan sleeves move well with your arms.

It is cut long in the torso and the shirt trims down at the waist, the sleeves are slightly longer as well (I usually prefer the sleeves a little shorter).

Fabric breathes quite well and wicks away moisture (does leave the big sweat marks that you see in some thinner fabrics). It has also held up to many washes without any signs of wear.

Great shirt overall


Great t-shirt

  • Familiarity:I've used it several times
  • Fit:True to size

I bought this shirt for rock climbing and yoga, but wear it regularly just about anywhere. The shirt was long enough even for my 6'4" body.
