Yes absolutely! We recommend that you wear it under your clothes in everyday life, or during physical activity, to maximize your results.

We offer free delivery within 5 to 8 business days across the US, Canada, and France. Most orders arrive before the 8-business-day mark, but we prefer to give a safe estimate just in case.
Is Aethon machine washable?
Yes, it is possible, but we recommend that you wash it at a low temperature to avoid damaging the fabric and keep the compression effective.

Three guys. Three different Tuesday mornings. One undershirt that fixed all of it.

I wear suits 4 days a week. This is now part of my daily uniform. Smooth, comfortable, and I look sharp without doing anything extra.
J
Tried Spanx, a generic Amazon one, one from a men's magazine recommendation, and one from a fitness brand. This is the only one that doesn't roll up, show through, or lose shape after washing.
P
I expected it to feel tight and restrictive all day. It doesn't. The compression is there but it doesn't cut off circulation or feel uncomfortable after hour two. Big difference from other brands.
E
Always hated photos at events. Wore this to my cousin's wedding and for the first time I actually like how I look in the pictures. Ordered two more colors the next day.
R
Any time I have a big presentation or meeting I wear this. It just makes me feel more confident walking in. Part mental, part physical — either way it works.
A

They still ride up when walking
M
I didn't like it
A
My order never arrived. It was ordered July/26.
You are a total scam!!!!
D
Initially I thought my choice of Medium is too small but is based on your size guide. After a day of wear however, size is good. Very comfortable and feels like my posture is improved.
A
Not compressing at all
A
Very nice fit,, going to try a few times will have to buy another
M
TOTALLY MISLEADING I WANT MY MONEY BACK THX
j
Very mad i was suppose to get it today and i need it for saterday going on a trip and the shipping was suppose to be free and i got charge that fause publicity
C
Trash
M
it`s no good
A
I love it very comfortable
R
Shirt is great, but too short in lenght, tends to ride up.
Other similar products I purchased were not as good, but longer, which made the sadly better.
A
Awesome....
A
It was advertised to be longer but came short
J
Happy with these undershirts
M
Poor quality. Small sizing. Low quality shipping package.
A
Not hardly compressive enough!
D
I need to return and swap them out for a size 2x please. Nice shirts just to short.
C
I live in Texas and was worried about sweating in a compression shirt. Surprisingly breathable. Wore it through an outdoor event in summer and it held up better than expected.
M
I'm between sizes usually and always end up with something too tight or too loose. The sizing guide on the site was actually accurate. First try and it fit perfectly.
G
I was worried about visible seams under a fitted white shirt. Zero lines. Zero outline. Nobody would ever know. That was my biggest concern and it's completely handled.
S
I travel for work every week. This packs small, holds shape, and looks just as good on day 3 of a trip as day 1. It's now in my carry-on permanently.
A
I know it sounds like marketing copy but the confidence boost is genuinely real. I carry myself differently when I'm wearing this. Shoulders back, posture better. Hard to explain but it works.
D
I was on the fence for weeks. The 30-day money-back guarantee is what made me finally try it. Spoiler: I kept it. Didn't need the guarantee but it's good to know it's there.
P
My tailor asked if I'd lost weight at my last fitting. I hadn't. Just wearing this under everything now. Coming from a tailor that was a pretty good sign.
F
No gimmicks. No crazy claims. Just a well-made undershirt that does exactly what it says. Smooth silhouette, comfortable all day, holds up after washing. That's all I needed.
