Summer: A Simple Guide To Men’s Undershirts

Summer is now in full swing and it’s getting freaking hot! I’ve seen photos of thermostats showing temperatures over 110 degrees!

As-is tradition for this time of year, there are lots of folks visiting UndershirtGuy.com looking for undershirts that will keep them cooler.  

While there are several new athletic t-shirt products leveraging fabric innovations that claim to keep the wearer a few degrees cooler or more, those products must be worn as the sole outer layer for them to perform.

Airflow is required to aid in the evaporation process, and in most cases, there is little to no airflow when wearing an undershirt [under] an outer shirt.

I’ve even found myself a little more sensitive to the hotter weather, and because of that I’ve been wearing my ribbed tank tops a little more frequently.

They do tend to keep me a little cooler than when I wear a full undershirt, but with less protection, this means my outer shirts have been getting soiled a lot quicker, especially in the underarm area.

See, even with using antiperspirant, my underarms are still sweating a bit and it transfers to the underarm of my outer shirt.

Hell, I’d love it if I didn’t have any underarm sweat, so I’m seriously considering trying a stronger longer lasting antiperspirant like Sweat Block, Klima, or CertainDri. I’ve even contemplated looking at sweat-blocking treatments like miraDry just as an experiment, but the cost makes it a little hard to justify.

Be sure to check out my Top 9 Sweat Management Solutions article. It contains information about sweat blocking undershirts, sweat proof underwear, various antiperspirant & sweat-reducing options, and much more.

Since you’ll likely be breaking out your undershirts more often due to the heat, I thought I’d share a great Guide To Men’s Undershirts article my friend Antonio Centeno from Real Men Real Style put together for the Art of Manliness.

In his article, Antonio cover the History/Origins of the Undershirt, as well as the various styles available, and makes some recommendations on which to wear and when.

There’s lots of great information available in the article, as well as in this video he created which recaps the article’s main points.

    Thanks for this. This was the most useful part of your site for me. I had researched synthetics vs cotton and this is the strongest argument staying with cotton. A second strong argument on your site for staying with cotton was that the undershirt’s function is to protect the dress shirt, so to simply wick the sweat from the skin right through to the expensive shirt defeats the purpose.

    • my pleasure klaus! that’s what i’m here for buddy!

      i definitely recommend a fabric that is absorbing or a blend of wicking/absorbing for a good and practical daily-wear undershirt. not that i fully oppose moisture wicking undershirts, because in certain circumstances they are totally fine. but generally speaking i prefer to recommend something that has some absorption properties to prevent sweat-through.

      now, if you don’t sweat very much, and are primarily wearing an undershirt to protect your outerwear from body oils or underarm stains, then you probably could get away with wearing a moisture wicking undershirt if that was your thing.

      those “cooling” shirt products are definitely designed to be worn as outershirts, not undershirts.

      though, there are some brands that are creating really lightweight undershirts, specifically designed to keep the wearer cooler. some that come to mind include: uniqlo airism undershirts, tommy john cool cotton, shirtless undershirts, underfit, ribbed tee retro fit or coolwear supima, mr. davis, etc.
