Updated review: I did not love the undershirts. They fit and they are as advertised, but too thin for my taste. Also I’m used to cotton and this feels very differently. It’s not for everyone. I... See more

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.

My son loves the v-neck undershirt. This is my 3rd purchase. I buy 5 each time and they last and last. The shirts are so very soft and keep their shape wash after wash. I would recommend the product.
I've had for several days. I'm headed to the boundary waters soon and I decided to test this shirt out for temperature and stink control. After 3 days of heavy sweating , no showering, the shirt still did not smell bad. I'm genuinely impressed. It fit well and never came untucked. So far so good! Only things is, find a Us manufacturer or post more about manufacturing ethically.
Love these T-shirts. Aside from being super comfortable, The fit and fabric are amazing. Love how they hug your body but are not tight. Makes trucking in with your shirt so much easier and less extra fabric bunching around the pant waist. Perfect for folks that still wear suits and dress clothes for work!!
I tried several t-shirts for wear to work and this is the best I've found. It's a fitted shirt that stays tucked in throughout the day and is extremely comfortable. I purchased 5 without trying it first and have zero regrets and will also purchase more in the future. I'm 5'9" and 180 with an athletic build and the large fits me perfectly.
The fabric is spectacular, the fit is perfect, I would have liked it a little shorter in length, but it's nothing I can't handle. I have been using UndrerFit for more than 5 years...
I have been looking for new undershirts, more comfortable, less baggy, etc....After a good amount of research, I decided to try UnderFit. I am so impressed, they are comfortable, soft, cool, basically everything I was hoping. I cannot speak to how long they last but, so far, I love them!!!
The length for my tall size was not wrong. It was long enough for a tall person AND it was long enough to stay tucked in forever. The Vneck is low and wide enough not to show which is what the primary functional purpose of an undershirt is. The material is thin, but that is a plus because it is light and doesn't interfere with your clothing. Also, the stretch material is not constricting. Fantastic.
I found this website on a whim while searching for an undershirt, and I decided to try one, and it worked out quite well. I will continue to use it as an undershirt for dress shirts. Shirt fit well, was invisible, and prevented me from sweating through my shirt on a hot summer day.
I'm always leery about ordering clothes online, but these shirts have passed my strict requirements and are extremely good in every way. I bought 3 beige, and I will likely follow up with another 3 white. So far, they are living up to their claims.
I buy for boyfriend and his response after getting the first one was "this is the best undershirt I've ever worn". I bought 3 more :)
I love the beige underfit shirt! Best part is how invisible they are underneath white shirts. Also, the length on them is perfect to stay tucked in if needed. I got 7 and wear them every day now.
My boyfriend won’t wear any other t-shirts. These are soft, and fit so well. He likes how they also stay tucked in.
Not much else needs to be said. These items fit great and make a person feel confident wearing them. I am 5'8" and 160ibs; I normally wear a small, sometimes a medium. In this brand, the medium is the right fit.
The return policy is fraudulent, they simply don't respond to your request. And the shirts kinda suck any way. Don't waste your time or money.

Material feels nice on skin. Product works as advertised, really helps to deal with heat when wearing a full suit and is very thin so does not interfere with other layers. V neck can't be seen with a regular t shirt but prevents armpit sweat being visible which is good.
UPDATE: Leigh contacted me and made my order right by shipping my shirts as promised per his comments below. The shirts are breathable, great and don't smell like polyester tends to. Changing my review to 4/5 stars. 5 for the product but I can't ignore the 8 month wait entirely.
ORIGINAL REVIEW:
I ordered 12/15/23. My card was charged and I got an order number in a confirmation email. It’s 2/17/24 and no progress. I’ve tried emailing support several times and using their web form also. No response. I think this place is going out of business.

I placed an order in mid November of 2023. I followed up after a couple of weeks as I never received shipping info. Leigh responded and said that the order didn’t process because the website let me place an order for an out of stock item. No problem I responded and said I would modify my order to something in stock. Since that I have reached out multiple times via email and through the website. It’s been radio silent since November 27th. At this point I just want my money back.

Two of three undershirts are coming apart at the seems and still no response from customer service. Hello? Is anyone there? Leigh?
I ordered a shirt on Sept. 5, 2023, received a confirmation email from Underfit and my credit card was charged. It's now been exactly one month and my shirt has not arrived and when I check my order status on their website it say, "on hold". I've emailed them twice via their customer service contact and have yet to receive a response.

I placed an order 8/28. Still shows "being processed" when I paid for 2-4 day shipping. Now at day 10. I've sent multiple emails to customer service and no response. I reached out via their social media. No response. I guess I got scammed???
