With a white undershirt, you can see the v neck and sleeves under many light colored dress shirts.

The moment you put on an UnderFit undershirt, you’ll notice a huge difference compared to other undershirts you’re used to wearing. To design the best men’s undershirts, we analyzed everything we hated about traditional, poorly-made basics. That’s why we set out to make an undershirt that:
You don’t need a six-pack to rock an UnderFit undershirt. They say clothes make the man. At UnderFit, we know confidence starts underneath.
You’ll never want to take this undershirt off! Our undershirts are made from TENCEL™ fabric blend, a highly-sustainable textile sourced from wood chips. The trees are sustainably farmed and our manufacturing process is “closed-loop,” meaning there is little to no waste.

Gotta tell you, it’s a very nice product. Good fit, good feel, good price. Comparatively, the UnderFit fits and feels very close (or as nice as) to the more expensive micromodal/lycra undershirts.
No rising, No billowing. We managed to get through a whole day without a single untuck from under our made-to-measure shirts.

These are the most comfortable and best fitting undershirts I’ve ever purchased. They do what an undershirt is supposed to do without adding any bulk. The tailored, close fit actually feels good against your skin. I really don’t even know I’m wearing them.
I have worn UnderFit undershirts for several years (since 2019 I believe) and have been super satisfied. The fit (according to the chart on website) is spot on. It snugs up to the torso and arms like a second skin. I get a v-neck because I love wearing crisp long sleeve shirts for business and casual wear.
Respectful and honorable dealings.

This is the best undershirt in the market, nItried 5 different brands before finding underfit. simply the best.
