Écrit par l'entreprise

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.

Fit advice by staff was amazing

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.

Questionable quality, even worse customer support

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.

Not a great fit , now what?

Not exactly what I was looking for
I received two undershirts and after trying one on the fit was not right for me. This is always a risk with online purchases. I reached out to the return department and they make the process of return and refund simple.

Love these shirts!!

Love these shirts! great fit, durable material, and as an undershirt help keep my other shirts in better shape. I have been wearing Underfit shirts for over 5 years now, and still a happy customer.

Change of Heart

In the beginning I didn't care for the first shirts I bought from Underfit . The more I wear them, the more I have grown to prefer them over cotton. Now they are pretty much all I wear as an under shirt. That drove my decision to purchase more in different styles and colors. I would recommend giving them a try if you are on the fence.

My Canadian order was shipped to…

My Canadian order was shipped to someone in California. I have sent an email to customer service & the owner Leigh McKenzie over 3 days ago and have yet to hear from anyone at Underfit.
Their customer service is non existent!

Réponse de UnderFit

Hi, thanks for calling this out. I should have responded faster, and that’s on me.

UPS had a tracking glitch that marked some packages “delivered” when they hit a transit facility in Torrance, CA, even though they were still in transit. Your order is either already delivered or still on the way. If it’s still en route, I can share the final-mile tracking link with the latest updates.

I’m here now and won’t leave you hanging.

No Customer Service

My order was delivered to an address when in the US when it was supposed to go to Canada. I have been trying to get a response from someone at Underfit but so far nothing not even an acknowledgment of receiving my messages.

Shirt didn’t fit well. Tried contacting customer service but no one replied after multiple attempts and can’t return.

Never shrink, stay tucked in!

These undershirts are above and beyond the best I've worn. They don't shrink or lose shape, they help wick away sweat more easily than cotton, and they always stay tucked in. The only thing you'd need to get used to is the slight see through material, which can be more noticeable with excessive chest hair. But it's an undershirt, so definitely not something to plan for!

With UnderFit, You Get a Lot for What You Pay For

UnderFit T-shirts are the best undershirts I've ever owned and will ever own. They're thin, they stay tucked in, they hold up great around the neck, and they last forever. I can't imagine wearing any other brand after going to UnderFit. Been wearing them for approximately 5 years.

Obsessed with these shirts

Obsessed with these shirts. Great fit, sweat resistant, comfortable and best of all, I can wear a white button up with two buttons opened and you won’t see it!

Excellent quality

Excellent quality. These were the first undershirts I have purchased in years, and they fit wonderfully. I like the way that they regulate temperature and moisture even on the hottest summer days. After over a year of wear, they're still reliable. I would highly recommend.
