Hot days call for a cool, comfortable shirt, and the Arc'teryx Men's Actinium Sleeveless Shirt uses quick-wicking, ventilated material to keep you going when the temperature rises. Whether you're working out in a hot, sweaty gym or pushing through a 20-mile day with a backpack strapped to your back, this shirt will help you stay cool. 

  • Viente fabric is lightweight, air-permeable, and quick wicking so you stay cool when you're 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
