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.

The problem with most undershirts is that they’re just T-shirts. UnderFit’s shirts are made from lightweight yet durable fabrics with a touch of stretch and are designed to be worn under your shirts.

Great Fit and Invisible Under Work Shirts

My husband loves these undershirts and already mentioned he will likely be purchasing more. The fit is perfect and true to size based on the chart. He ordered a medium and it fits just right. They are long enough to stay tucked in and completely invisible under his work shirts. He also likes that he can leave the top two buttons unbuttoned for a more casual look without anything showing. Overall, a fantastic product and a great addition to his wardrobe.

Exactly what I was looking for

I ordered 3 of these shirts and they exceeded my expectations. They are soft, comfortable, stretchy in the right places and are great for button up shirts. All of the claims they make on their website about these shirts are 100% accurate. I’ve only washed them once so I can’t speak to their durability, but assuming they hold up, I will absolutely order more. I’m glad to have found these and I anticipate my dresser will be full of these as I phase out my old undershirts.

V-neck undershirts

The V - neck shirts were extremely soft and comfortable. A perfect fit. Definitely could see getting more in the future

Fantastic!

This is the 3rd type of these type of undershorts that I have purchased and it is my favorite. The first was comfortable but white. The second was too tight and I didn’t love the armpit pads. Yours fit great and is the perfect color. I will buy another send or third one if you should send me a discount code! Thanks so much, Nick Vassel

Excellent undershirt

Excellent undershirt. Go for it guys. You will never regret. Now became my favorite undershirt. Select the smaller one if you are in between the sizes since it stretches a lot
