You'll be hard-pressed to find a button-down as breathable as the Marmot Men's Notus Shirt. Its AirExchange performance fabric is air-permeable, which breathes the moment you put it on, compared to most breathable fabrics that only breathe when you start sweating. The fabric also wicks moisture, dries quickly, and packs easy for travel to hot destinations.

Lightest most versatile shirt I own

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

I wanted something for all-around use in Africa. It gets hot here, so I wanted extremely light and breathable, but it has to meet the dress code at the office as well! This one breathes really well, and doesn't cling with sweat like a lot of other shirts that claim to be breathable. As a bonus, it's so light and packable I don't even have to consider it when traveling (if I'm not wearing it, that is, which I usually am). Given that, it's had no durability issues with all the outdoor use I've put it through.

Love these shirts!

I first bought this in the vintage navy and couldn’t believe how lightweight and breathable it was. I don’t want to wear anything else in the heat, so I also bought the light khaki. They fit great, look great and breath like crazy. I can’t imagine going to any kind of event or even just walking around in the heat in anything else.

Not for me

Picked this up in the Vintage Navy. Wanted to love it with the mountain/tree design, but it's not what I was hoping for. It's definitely a nice light and breathable shirt, which would be great for active pursuits. However, I found the fabric to have almost a shimmer to it unlike the photo and it is definitely more of a "dad fit" (no offense dads!). I was hoping for something with a bit more of an athletic fit, so this one just wasn't for me personally.
