I have had a "love/hate" relationship with undershirts for most of my life. I am extremely fit and muscular with broad shoulders, defined chest and, although I long ago gave up on reclaiming my six-pack, I don't have much of a paunch. No matter how much I work out, however, my neck is disproportionately small (okay, maybe not enough to qualify for a freak show). That makes finding the right size Tee shirt extremely difficult. Most Tees fit my body but leave my neck rattling around in a loose collar. (Okay, a slight exaggeration to make a point). So, back to UnderFit. I usually order mediums in Tee shirts, but the size guide recommended large for my height and weight, so, although concerned about circumference of the neck hole in a large Tee, I followed the advice. I received my first order of crew necks tees yesterday. Each shirt is packaged in its own zip lock bag. They appear very light and skimpy at first, but as soon as I slipped into one, those concerns vanished. My first impression was how soft and supple it felt. My second sensation was how cool it felt against my skin. It didn't feel like I was adding a layer of clothing. It felt like part of my skin. Seriously! And the neck hole was made fit like it was custom-made for me. The large side conformed to my body, so "large" was the right choice. I wouldn't characterize the material as diaphanous, but I probably would not wear the UnderFit Tees by themselves--hence the title "UnderFit." Finally, since I am meticulous in the care and laundering of my clothes, each shirt came with a tag that stated, "Wash and dry however you want." One less hassle. I sat down to practice my guitar this morning, but took time away from that beloved pursuit to share my experience with UnderFit. I honestly can attest that these are the best Tee shirts I have EVER owned.

Response time was great with guidance. I pulled the trigger on a three pack. First day first shirt. Fitted. Well constructed-no weird seams. Plenty of length for my long torso. Threw one on under a cashmere shawl sweater. No sweat. Smooth as silk. Never knew I had it on. Not once. No small thing. Email follow up upon order is awesome-every single step of your order placement through delivery is email notified. If customer service matters, read the way they handle complaints here-professionally and with care. Now, I did discover I had tiny man nipples :-) wearing my new UnderFit. My wife said it was cool. First impressions matter :-)!

Wonderful fit. They do just what they are designed to do. I wouldn’t be without them.

Having found these well made, light, breathable and invisible undershirts, I'm beyond happy. Often sellers charge a premium for tencel material undershirts, and do not bundle but Underfit has created a great package solution at a reasonable price and with fast delivery (in the UK and received in less than 7 days after order!). With some more colors in the range to support other skin tones, and some more designs, I can see myself buying more in the future. 10/10

It’s a great a solution for an undershirt and it’s also versatile in the different ways it allows you to wear your clothes without concern of the undershirt showing. Leigh helped me through the purchase and was also fantastic.

It snugs up to the torso and arms like a second skin. I get a v-neck because I love wearing crisp long sleeve shirts for business and casual wear.

Experience The UnderFit Difference

  • Icon

    Super-soft fabric

    The secret to UnderFit’s superior comfort starts with the fabric. We use a TENCEL™ fabric blend that feels great against your skin, provides all-day comfort all day and is built to last.
  • Icon

    Lasting durability

    What good is an undershirt if it tears or has holes after only a few uses? That’s why we use durable TENCEL™ fabric in our shirts. Unlike cotton, it has an exceptionally high tensile strength, making it harder to rip and tear. It also means your undershirt will continue to keep its great shape after repeated wear and washings.
  • Icon

    Greater breathability

    In addition to the softness, UnderFit’s TENCEL™ fabric also offers superior breathability. This means that your undershirt will help you stay cool when things start heating up.
  • Icon

    Superb temperature regulation

    Whether you’re at work or out on the town, you want to minimize heat as much as possible to avoid excessive sweating. Our TENCEL™ fabric blend helps to regulate temperature to let your body breathe when the heat goes up.
  • Icon

    Advanced moisture absorption

    Just because you’re perspiring doesn’t mean others need to know about it. UnderFit offers the best undershirts for men who sweat, thanks to advanced moisture absorption that stops sweat in its tracks, so the rest of your clothes stay dry and fresh.
  • Icon

    Odor resistance

    TENCEL™ fabric has moisture-wicking technology to limit moisture, keep you dry and prevent odor-causing bacteria. It’s just like the moisture wicking you expect from high-performance workout apparel, but designed for your day-to-day lifestyle instead.
  • Icon

    Eco-friendly & sustainable

    We care about the environment just as much as we care about making the best mens undershirt! That’s why we only source our raw material from sustainably grown forest plantations.
