Prompt fulfillment and a high quality product. I have had these undershirts for over a year and they are as good fitting as when they were new.

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.

As I lost more than 50 pounds, I needed to get V-neck t-shirts that were much smaller. I tried UnderFut and was pleasantly surprised. The real test of a shirt is: What do you reach for first? And I’ve been reaching for UnderFit every time.

I have always purchased stretch fit undershirts from top name brands like Jockey and Alfani. I saw an ad for Underfit, and decided to try them. The fit was better and very light weight as well as cool. Have placed several order’s and will never change. I use them under a shirt, just with Jeans, as well as with my gym pants when I go to the gym. Worth the price.

Deixo aqui a minha sincera opinião e alerta sobre a Underfit PT. Comprei uma camisola por 29,90 € com a promessa de entrega em 2 dias úteis, uma vez que a marca é anunciada como sendo de Portugal. Para meu espanto, a encomenda demorou mais de 21 dias a chegar e veio diretamente da China. Se soubesse que viria da China, com esse valor teria comprado 4 artigos semelhantes por 20 € noutras plataformas. Quanto à qualidade do produto: Zero diferenças em relação a modelos consideravelmente mais baratos do mercado. Não noto qualquer tipo de benefício ou progresso no uso da camisola. A qualidade deixa tanto a desejar que levanta sérias dúvidas sobre a autenticidade do produto. Para agravar a situação, o apoio ao cliente é horrível. Enviei vários e-mails e ninguém respondeu. Considero uma publicidade enganosa e um serviço fraudulento para com o cliente. Até ser devidamente contactado pela empresa com uma resolução, a minha posição mantém-se: o produto não vale de todo o valor pago e a experiência foi lamentável.

Fit advice by staff was amazing. Suggested a small, bought small and it fit brilliantly. It is completely invisible under my dress shirt even with two buttons unbuttoned. Not odor-resistant at all. I didn't even sweat and the smell from the armpit area even after wearing for only an hour was extremely noticeable. I don't like how it feels on the skin, feels too synthetic to me. However, it doesn't ever come untucked when I wear these undershirts which is a bonus and customer service sounds like human beings rather than AI.

They make the best undershirt I've ever worn.

Great shirt. Good service.

I ordered 2 UnderFit shirts, which feel quite soft and are comfortable to wear. However, I experienced immediate quality issues with a seam under the arm on 1 of 2 shirts separating after my first use. I contacted UnderFit for customer support and I initially received a response indicating they would help me with my quality concern, but then the communications abruptly stopped. Despite 3 attempts on my side to get help, UnderFit never again responded to me. Never before have I experienced that kind of disrespectful treatment from a brand claiming to offer a “premium” product (at a very high price point, as well). Overall, a very disappointing experience.
