Best Undershirts to Wear Under T-Shirts

If you’re looking for an undershirt to wear under a t-shirt so the collar of the undershirt doesn’t show, this reader’s email may be right up your alley.

Hi Tug,

I’ve recently discovered your site. I’ve been trying to find the perfect undershirt for years, and I hope you can help.

I wear a dress shirt only a handful of times a year, but I wear T-shirts frequently. Therefore, 99% of undershirt recommendations are useless to me.

My undershirt needs are purely for pit stain management. That said, the undershirt I’ve been searching for needs to have the following characteristics:

1. Wide/deep crew neck so that it’s not seen beneath t-shirts with crew collars.

2. Short sleeves so that they’re invisible beneath t-shirts with shorter sleeves.

3. Desirable qualities, such as good feel, proper fit, and quality fabric with breathability. 

But honestly, if I can find something that meets criteria 1 and 2, I’ll be ecstatic. So can you provide a recommendation or two for me from all your undershirt testing?

Thanks,

Michael

Hey Michael,

Good to hear from you, buddy, and thanks for your question!

Since you’re looking for pit stain management, I wouldn’t recommend tanks since they won’t provide underarm protection. One thing to consider about scoop neck, deep crew neck or wide neck undershirts is that their lines can be visible under t-shirts and dress shirts

Based on the requirements you’ve stated, here are some excellent options to start with:

  1. Thompson Tee
  2. Ribbed Tee
  3. Ejis
  4. Neat
  5. Tommy John
  6. JT Invisible Undershirts
  7. Mika Jaymes

1. Thompson Tee

Stop sweat marks and pit stains for good with a Thompson Tee. Made with ultra-soft premium cotton, their men’s deep V-neck undershirt features patented sweat proof technology to block sweat stains and odor.

  • Available in four colors
  • 30-day risk-free guarantee
  • $32.99

2. Ribbed Tee

Ribbed Tee’s EVO TENCEL deep v-neck shirt is “Cool like linen. Soft like silk.” Its longer-cut back keeps it tucked in, while the deep v-neckline keeps the shirt hidden under your clothes.

  • Available in three colors
  • 94% Tencel, 6% spandex
  • $34.00

3. Ejis

Ejis combines cotton with micro modal fabric to enhance sweat-absorbing and sweat-blocking properties, keeping shirts dry and clean.

  • Available in three colors
  • Extra-long to stay tucked
  • $32.99

4. Neat

Neat’s technical v-neck undershirt features Neat™ fabric that keeps sweat hidden. However, the shirt may look wet even when dry, so it’s best not to wear this shirt as a stand-alone tee. 

  • Available in white

  • $29.99

5. Tommy John

Tommy John’s deep v-neck undershirt has 30% more stretch than its original undershirt and never comes untucked. In addition, its tapered design stays fitted under clothing, keeping you looking slim.

  1. I recently purchased the JT original invisible undershirt. I found the sleeves too long. It wasn’t possible to wear it under a t-shirt without the sleeve peeking out from underneath.
