UnderFit undershirts are cut longer and lightly hug your hips and below, to stay tucked in all day. Our fabric is ideal for undershirts due to its exceptional softness, advanced moisture absorption, odor resistance and superb breathability. If you want to remain less comfortable in your run-of-the-mill undershirt, by all means, DON’T buy an UnderFit.

Great material and fit. My only negative is how deep the V is on the V-neck shirts.

Hey Chris, The V-Neck is deep, but its depth is so it hides beneath an oxford, even if two buttons are undone. A v-neck peaking out isn't fashionable and can ruin an outfit. Thanks
Great fit and don't notice I'm wearing it all day. Easy to wash and care for. Thank you for creating a great product!

Like most people I know,I have to keep my undershirt tucked in,OCD sucks. I have bought other brands,and manufacturers of undershirts than I care to count. So when I had all I could stand of continously returning my shirt in,I went shopping yet again. I browsed other pages and websites in search of another disappointment 🙄,when I was about to get completely irate, I found UNDERFIT. After reading the reviews,I was still sceptical, I'm 6'1 310 lbs,broad shoulders,56-58 chest,obviously these were not for me. I decided to order one,$25.00 each is pricey for something that may not hold up to my expectations.when I received my one shirt,I was impressed by the material and quality. I am a local truck driver,and I am constantly in and out,walking,bending,stooping,climbing and bouncing up, down in the seat.my UNDERFIT shirt never moved,shifted,or rose up,not even a little.i have washed it every day, so I can wear it the next. I have finally found my last undershirt ever,I placed an order for 5 more today,and seeing my birthday is around the corner, I will be asking for more. I am completely satisfied with these shirts,but what sold me on the initial purchase was they guaranteed satisfaction, or my money back,NO QUESTIONS ASKED. if you are in doubt, DON'T BE,buy from UNDERFIT, you will not regret it.

Smartest designed high quality incredibly comfortable no-ride undershirts. No others need apply.

Great company, excellent service, wonderful products! The crew and v-neck undershirts really are "simply perfect". The only undershirts my husband will wear!

I have been on the search for the best undershirt for years like Daniel Boone on a hunt for the great grizzly bear. Well, I've found my grizzly bear and they are the UnderFit undershirts! The quality is great. They stay tucked in and I love the snug fit of the soft material. Bravo Underfit!
