Keep going.

The Arc'teryx Motus Crew has been proven to push runners past their limits; when your torso isn't dripping with perspiration or overheating, you are much more likely to performance better and make your competition look weaker. Quick-drying Phasic SL fabric wicks moisture away from your body to evaporate quickly while hydrophobic fibers next to the skin prevent you from feeling clammy when you're cooling down. It stretches, breathes, and keeps form after many uses; what it doesn't do is rub against your skin with nasty seams. You'll barely feel the flatlock seams at all, really. A tough of sun protection gives you the confidence to stay out just a little longer without worrying about skin damage from harmful UV rays. This layering piece is great for touring or cold-weather climbing when altering between high-output aerobic activity and sitting still, or for warmer-weather runs where you want the sun protection but don't want to overheat.

So good I bought 2 more.

I purchased this shirt because I was looking for a warm weather hiking and trail running shirt that offered protection from the sun. I've used it on several weekenders, trail runs, and twice for over 14 days straight as my one and only shirt. The verdict? Stink-free, suburn-free and comfortable the whole time - so comfortable I forget I'm wearing long sleeves. Besides some wear on the screen-printed logo, the shirt still looks brand new. I love it so much I recently purchased 2 more.

I bought this as part of the layering system and to wear as a stand alone in warmer temps (I live in the Pacific NW so I dont have to content with much heat but on those hawaii and desert trips this shirt may do the trick).
Very thin, comfortable slick feel. Seems to breathe well.
I sized up to have a looser feel.
On the pricey side but if you like performance gear that helps justify the cost.

fantastic running shirt

  • Familiarity: I've used it several times
  • Fit: True to size
  • Height: 5' 3"
    Weight: 135 lbs
    Size Purchased: Small

Fits perfectly - not too tight, not to snug. shirt is very light, I can hardly feel it. the fabric is smooth but feels nicer than cheaper synthetics. great color - does not show huge sweat marks.

Breathes, Sun Protection & doesn't stink

  • Familiarity: I've put it through the wringer
  • Fit: True to size

Even though this is design for runners. I has been super nice as a base layer for alpine climbing. It provides protection from the sun and breathes as the same time so I don't need sunscreen on my arms. It can get pretty hot on a glacier with the sun reflecting off the snow and this shirt does well to help me regulator my body temp. Then afterwards when I grab a bite at In-n-Out I don't smell like I have showered for 10 days. I really like how light it is too. It is just a great product all around.

Exceptional Breathability. Non-Stink

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

Comfortable, dries quickly, and doesn't stink. The arms are just the right length. I even like the colors.

Wore a couple of these on the equator for a few days and never noticed the heat--a real boon for those of us who need to cover up in the sun.

Worth the crazy price.

fashionable, active endeavors are great in this, fits athletically. 6'4 195 large is perfect fit. Can wear in 80-90 degree heat too.
Get one and fall in love.
