When the mercury jumps and your afternoon hike promises to turn into a sweat-pouring mess, throw on your Arc'teryx Men's Actinium Short-Sleeve Shirt and keep your cool. Quick-wicking fabric pulls sweat away from your skin so it can evaporate faster and speed up your body's cooling process. When you're cool and comfortable, you can cover more ground and see more country.

  • Viente fabric is lightweight, air-permeable, and quick wicking so you stay cool when your working hard
  • Aegis treatment inhibits the growth of odor-causing bacteria so this shirt doesn't get funky between washing
  • Mesh underarm and shoulder-strap panels ditch excess heat and bring in fresh air to cool you down
  • Flatlock seams reduce friction and help prevent chafing

What a great shirt. It is so amazingly comfortable and cool, I bought all the colors. The bright colors are sweet but the gray is really nice looking.


Another Arc'teryx Hit

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

I bought this to augment my Motus Crew collection, and I'm not disappointed. It is very light and breathable, not to mention nice looking. I love the way it feels, as well.



  • Familiarity:I've used it once or twice and have initial impressions
  • Fit:Runs large

This was my second Arcteryx shirt. And perhaps i didnt know exactly what i was getting, but for the money, i will just stick with Marmot. This shirt does stay cool, very well ventilated, and it dries fast. Also takes some scrapes that would have snagged a lesser shirt. But I just dont care for the fit. It seems a bit loose, especially around the neckline. I guess i was hoping for something with a snugger fit. Maybe my mistake in sizing, i always get medium, but should have got a small?? But it says Athletic fit. Now it mostly stays in the drawer.


My favorite running top

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

Expensive but great when it gets hot. 4/5 given the price but if you are just looking at the quality then I'd give it a 5.


What did you expect...

    It's simple. For the price and the quality, you can't beat this. It does everything as advertised. I have a few nike running shirts and the difference in wicking and breathability is clear on those warm days.

    You get the Arc'teryx quality that you've come to expect at a cheaper price.
