Description

Light seamless compression that holds your middle in place, so your shirt falls straight from your chest instead of your gut.

It holds, it does not squeeze. Light, even pressure across your midsection: enough to hold the shape, not enough to fight you when you sit down after lunch.

Seamless, so it is the only layer anyone sees. No side seam, no bottom hem ridge, no shoulder line telegraphing through a white shirt. It goes on in about ten seconds and it does not roll back up.

Product details

Seamless knit with four-way stretch. Knitted in one piece, so there is no side seam and no bottom hem ridge.

Colors: Black and White.
Sizes: S to 5XL, cut long so it stays tucked.
Compression: light and even across the midsection. Built for a fourteen-hour day, not for the gym.

Ships flat in a plain bag. Nothing on the outside says what is inside.

Size and fit

Size by your chest, never by your weight. Measure around the fullest part of your chest, under your arms, with a shirt on. That number is your size.

Between two sizes, take the larger one. It still holds, and it stays comfortable after lunch.

The hem does not roll. The shoulder line does not telegraph through a white shirt.

Wrong size? We ship the right one free. You keep the first one until yours arrives.

How to wash it
  • Cold machine wash, gentle cycle, in a mesh bag.
  • Hang to dry. Never tumble dry: heat is what kills the stretch.
  • No fabric softener, no bleach, no ironing.

Washed this way it holds its shape for well over a year.

Shipping and delivery

Ships from our US warehouse. Most orders leave within 2 business days and land 3 to 5 business days after that.

You get a tracking number by email the moment it ships.

90-day fit guarantee and free exchanges

Ninety days. Nobody else in this category goes past sixty.

Wear it. Wash it. Wear it to work, to a wedding, to eighteen holes. If it is not doing what this page says, email us inside 90 days and we refund you. You do not ship anything back. Keep the tank.

Wrong size is not a return. Tell us and we send the right one free, and you keep the first one.

Find your size

Measure around the fullest part of your chest, under your arms, with a shirt on. That number is your size. Never size by your weight: two men at 220 lbs can be shaped completely differently.

Size Chest (in) Chest (cm)
S 36 - 39 92 - 100
M 39 - 41 100 - 105
L 41 - 44 105 - 111
XL 44 - 46 111 - 117
2XL 46 - 49 117 - 124
3XL 49 - 51 124 - 130
4XL 51 - 53 130 - 134
5XL 53 - 54 134 - 138

Between two sizes, take the larger one. This works by holding steadily, not by strangling. 4XL and 5XL are the same width: the 5XL is simply longer, for taller men. Wrong size? We ship the right one free, and you keep the first one until the second lands.

Real Stories, Real Results

What men told us after ten days in the tank.

5.0

“My shirt finally falls straight.”

Broad shoulders, all the weight up front. Every shirt either pulled across my stomach or hung on me like a tent. First day wearing this under a button-down, the shirt fell from my chest instead of my gut. That's the whole thing for me.

“I stopped tugging at my shirt all day.”

I used to pull my shirt down every time I stood up. Ten days in, I haven't done it once. It doesn't roll up at the bottom and it doesn't fight me when I sit down after lunch. I ordered two more.

“Nobody knows I am wearing it.”

I was worried about lines showing through a white shirt. There are none. No side seam, no hem ridge, nothing across the shoulder. My wife asked if I'd dropped weight. She still doesn't know about the tank.

Feel stronger and more confident again

A flatter middle, shoulders pulled back, and a shirt that falls straight down instead of over your gut. All of it under a tank nobody can see.

It is not a diet and it is not the gym. It is ten seconds in the morning, and you stop checking your reflection in every window you walk past.

Feel stronger and more confident again

Made for the body you have today.

You’re not here to be told to lose weight or change your habits. You’re looking for something that works with your body as it is today.

CLEMFIT TANK™ holds and smooths the chest, belly and love handles so your T-shirt can sit cleaner over them.

Same man. Same body. Same T-shirt. Only a CLEMFIT TANK™ was added underneath.

Made for the body you have today.

Standing still in front of a mirror proves nothing

These are the four moments that give a compression top away. Judge it on these.

Homme assis a un bureau, chemise ouverte pour montrer le debardeur : il est encore a plat et rentre. Meme homme et meme lumiere que les 3 autres cartes.

Sitting down

Twenty minutes in a chair is where most tanks roll up into a band across the stomach. The long cut stays under the waistband instead.

Meme homme, les deux bras leves, chemise ouverte : le bas du debardeur n'a pas bouge.

Both arms overhead

Reaching is what drags a short tank up your back. Watch the bottom edge, not the chest.

Meme homme penche en avant, de trois quarts, chemise ouverte : le debardeur suit le corps sans se plier.

Bending over

Bending is where a shirt untucks and a tank folds. This one is cut to move with you and drop back flat.

Who this is not for

We would rather you did not order than order the wrong thing. Skip it if any of these is you.

You want to lose weight

It will not do that. It changes how a shirt hangs on the body you have today. Nothing more.

You want it for the gym

It is built for fourteen hours under clothes. A training top is a different garment. Buy that one.

You want maximum squeeze

This holds at light, even pressure. If you want to be strapped in, buy the tightest thing you can find. You will take it off by lunch.

You cannot wear one more layer

It is thin, but it is a layer. If one t shirt already cooks you in July, be honest with yourself.

What ninety days actually look like

No melting, no burning, no weight-loss claims. Here is the honest order things happen in, and where we stop.

Day 1
  • Your shirt falls straight: the line drops from your chest instead of draping over your stomach, the second you pull a shirt on over it.
  • Nothing rolls up: no ridge at the bottom hem, so your hand stops going to your waist.
  • Nobody can tell: knitted in one piece, so there is no side seam and no shoulder line under a white shirt.

This is the cut, not a result. It is the same on day one and on day ninety.

Week 1
  • You stop tugging: most men notice that before anything else. The reflex simply goes away.
  • You stand taller while you wear it: steady light pressure on the skin keeps telling your body where it is.
  • It stops being a decision: ten seconds to put on, fourteen hours of not thinking about it.

The posture effect lasts while you wear it, and only while you wear it. A shirt does not retrain your back.

Weeks 2 to 4
  • It stops being a decision: you are not choosing to put it on any more. It is on before you have thought about it.
  • The fit does not drift: no bagging at the waist, no stretched neck, no thin patch over the belly after a month of daily wear.
  • Nothing burns: no calories melt, nothing sweats out. This is a layer, not a treatment.

Nothing on this page depends on your weight changing. If it changes, that is your work, not the tank's.

Day 90
  • Still the same shape: washed cold and hung to dry, the knit keeps its recovery well past ninety washes.
  • Still invisible: no shine, no thinning, no seam printing through a white shirt.
  • Still your call: if it is not doing what this page says, email us and we refund you. You keep the tank.

That is the whole promise, and it is the only one we make.

Does the job. Took a while to get here

No issue with the tank itself, it does what they say and it hasn't rolled on me. But it took nine days and the tracking sat on the same line for four of them. I'd buy again, just don't order it for something you've got on Saturday.

Tall guys, read this before you order

I'm 6 foot 4. The 2XL fit fine around the chest but sat higher on my waist than I wanted. Emailed them, they said take the 5XL for the length, it's the same width as the 4XL. They sent it free and that one's right. Would have been five stars if I'd got it first time.

My shirt finally falls straight

I put a white oxford on over it and looked down and the shirt just went straight down from my chest. That was it. Ten seconds. I've spent four years buying bigger shirts to get that and it never once worked.

Fourteen hours, no rolling

Put it on at 6:30 for a shift and took it off after dinner. Didn't roll up once. My old compression shirt used to bunch under my belt by lunch and I'd be tugging at it in the parking lot.

Nobody's noticed and that's the point

I wear it under a polo at work five days a week. Nobody's said a word. No seam line, no ridge at the bottom. My wife only knew because I told her.

Size up if you're between two

I ordered L off my weight, 205 lbs, and it was too much squeeze. Measured my chest like the page says, 44 inches, so XL. They shipped the XL free and told me to keep the first one. XL is right. Read the size part before you order, seriously.

Golf shirt at 4 PM

This is the one I bought it for. Eighteen holes in a light grey polo, no jacket, nowhere to hide. Looked at the photos from the ninth tee after and I wasn't looking for my gut first for once.

I stopped doing the mirror check

Didn't expect this one. I used to stand in front of the mirror before leaving and turn sideways. Haven't done it in about three weeks. Didn't even notice I'd stopped until my daughter said something.

It holds. It doesn't strangle you

I've got two of those sauna vest things in a drawer. Could barely get them on, sweated through everything, took them off at lunch. This one I forget about. That's the whole difference.

Tucked in for the first time in years

Tucked in used to put my stomach on display, untucked made me look like a slob. That was the choice. I tucked a shirt in at a wedding last weekend and it was fine. That's not a small thing to me.

Good. Warmer than nothing, as they say

They tell you on the page it's a layer so it's a bit warmer, and that's honest and true. In August in Georgia I feel it. Still lighter than the second t shirt I used to wear for the same job, so it stays.

Raised my arm on a ladder. Nothing came up

Every shirt I own rides up when I reach for something. This doesn't. Went up a ladder to change a bulb and nothing moved, nothing showed. Sounds small until it's the thing you think about all day.

Went back for the three-pack

Bought the two pack to see. Wore it four days straight because I didn't want to go back. Ordered the bigger pack the following week. Get the pack, otherwise you'll be washing one every night.

Works, but the black faded a little

No complaints about the fit, it does what they say and it hasn't rolled. But the black went a shade lighter after about six washes. I was using the mesh bag, cold water. Four stars for the fit, two for the color, so three.

My uniform sits right now

I'm on my feet twelve hours in a work polo. The shirt used to catch on my stomach and pull sideways. Hangs straight now and I'm not pulling it down between rooms.

Not a diet, and they don't pretend it is

What sold me was the part where they say what it won't do. Everyone else in this aisle promises you fifteen pounds. This is a layer that changes how a shirt hangs. That's what I wanted and that's what showed up.

Ten seconds, no wrestling

I was worried I'd be fighting to get into it every morning like those neoprene things. Goes on like a tank top. That's it.

Under a white shirt, genuinely invisible

White dress shirt is the hard test so I checked in daylight by a window. No side seam showing, no line at the bottom, nothing across the shoulder. Couldn't see it and I WAS looking for it.

Exchange was painless

Ordered 2XL, needed 3XL. Sent one email, they shipped it next day and told me to keep the other one for my brother. No form, no return label to print. Docked a star because I shouldn't have needed the swap, but honestly that's on me for not measuring.

Fifty two, gym three times a week, still had the gut

Cardio three times a week and pickleball, and the middle kept growing anyway. I wasn't going to out train it. This doesn't fix that, it just takes it out of the picture while I keep working on it. Fair deal.

90 DAY FIT GUARANTEE

Ninety days. And you never ship it back.

Wear it under a shirt for ninety days. To work, to a wedding, to eighteen holes. Wash it as many times as you like.

If it is not doing what this page says, send us one email inside ninety days and we refund you in full. You do not print a label. You do not pay return shipping. You keep the tank.

Wrong size is not a return either. Tell us your chest measurement and we send the right one free, and you keep the first one.

Questions men actually ask

Does it roll up?

No, and that is the whole design brief. It is seamless and cut long, so it stays tucked and stays down.

Rolling is what happens when a garment is too tight in one band and has a hem to catch on. Ours has neither.

Will anyone be able to tell I am wearing it?

No. No seams, no hem line, no ridge. The photos on this page are shot under a white shirt and a light polo on purpose, because those are the two that show everything.

How do I know what size to get?

By your chest, not your weight. Measure the fullest part of your chest with a shirt on. Between two sizes, take the larger one.

And if it is wrong we swap it free and you keep the first one.

Is it hot?

It is a light layer, so it is warmer than nothing. We are not going to tell you otherwise.

It is lighter than the second shirt a lot of men wear for the same reason, and that is usually the honest comparison.

Can I work out in it?

You can, but it is not a training top. It is built to be worn under clothes all day.

How long does shipping take?

It leaves our US warehouse within 2 business days and usually lands 3 to 5 business days after that.

Shipping is free from $50. Below that it is a flat $4.95.

How do I wash it?

Cold machine wash, hang to dry. It comes with a mesh bag from 4 tanks.

Do not tumble dry it. Heat is what kills the stretch.

What if it does not work for me?

90 days, full refund, and you do not ship it back. Keep the tank. Keep wearing it while you decide.

Anything else: hello@clemfit.com. We answer inside one business day.

You do not need a bigger shirt. You need your shirt back.

Ten seconds in the morning. Nobody knows it is there. 90-day fit guarantee, free size swaps, nothing to ship back.
