UnderFitUnderFit 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.

Comprei uma camisola na Internet online da Underfit pt e fui burlado, paguei no dia 4 de Setembro de 2026 e até agora não recebi nada. Enviei emails, e ninguém me respondeu até ao momento. Quero o meu reembolso de 19.99€. Como faço para me devolverem o meu dinheiro.

Efetuei o pagamento a mais de dois meses e até ao momento a minha encomenda não chegou, nem sequer consigo rastrear a mesma...

O Site desapareceu após uma compra. Aparentemente fraude a mais de uma semana e não recebi nada.

Fake company. They don't send any orders and simply keep your money. They provide you with a tracking link to follow the status of your order, and later you receive a notification saying that it has been delivered, when in fact you haven't received anything at all.

Been wearing UnderFit shirts for over a decade (I am wearing one now) and over 150 pounds of weight loss. The smalls are a little tight (I'm 5'9 140 lbs) but the length remains spot on. The undershirts hold up well over repeated washes in cheap apartment washing machines/driers. What else can I say?

I've purchased twice from UnderFit. These are high quality t-shirts that don't add the bulk of a typical cotton T-shirt. They truly do not show through dress shirts and fit great. The ordering and shipping process was smooth and quick. Highly recommend!

Fantastic undershirts. These have to be the softest and best fitting shirts thatI’ve ever found. The fit is perfect and they are extremely soft and comfortable. I will definitely be ordering again. A+. Thank you.

Easy to order, with great follow-up to ensure my satisfaction. The undershirts fit very well and are so comfortable that I barely notice I’m wearing one under my shirts. I’ve definitely found my go-to undershirt! I love doing business with small companies that go the extra mile to make sure their customers are completely satisfied. Highly recommend!
