One important thing: these sizes are already calibrated for compression. You do not need to size down to get the compression effect, we have already accounted for that. Your true size will give you a firm, effective compression fit from day one. If you want an even tighter feel, you can go one size down, but your true size is all you need.
If you are between two sizes, go one size up for a comfortable all-day fit, or stay at the smaller size if you prefer a firmer feel.
Our recommendation: if you are unsure, take advantage of our Buy 2 Get 1 Free offer and order two different sizes or colors at once. That way you can try both and keep the one that feels best, or keep all three in different colors for different outfits. With free returns and free exchanges, there is no risk. If anything is not right, just contact us and we will sort it out immediately.
How does it work?
How does it work?
outsidezi™ uses a triple-zone compression system that simultaneously targets your chest, love handles, and belly, all three problem areas at once, not just one.
The moment you put it on, three independent compression panels work together to flatten your belly, lock in your love handles, and reduce the appearance of your chest. The result is visible in under 30 seconds.
What makes it different for bigger men: most compression shirts apply uniform pressure across the whole torso with no targeting. They were also designed for slimmer frames, which means they are too short, too tight in the wrong places, and ride up constantly on a bigger body. AlphaCore is extra long to fully cover bigger torsos, uses 80% Ionic Nylon, a higher grade fabric that stretches properly with a larger frame instead of fighting it, and goes up to 5XL, engineered for bigger bodies from the start, not just scaled up from a medium.
The No-Roll waistband solves the number one complaint about every other compression shirt on the market. It is structurally engineered to stay exactly where you put it from the moment you leave the house until the moment you get home. No riding up. No readjusting. No thinking about it.
Put it on under your shirt and forget it's there. Nobody around you will know you're wearing it. They'll just notice something looks different.

Instant Difference
No gym. No diet. Just put it on.
Real Men. Real Results.
Look better the second you put it on.
Generic compression shirts squeeze everything the same way. Outsidezi uses three independent compression panels, each targeting a specific zone,chest, love handles, and belly,exactly where larger men need it most.
Never rides up. Fully covers your body.
The bigger the belly, the more pressure on the waistband, and the faster a standard shirt rides up and untucks. outsidezi's waistband is structurally reinforcedto hold against that pressure from morning to night. The shirt is alsocut longer than anything else in the category, so it stays fully tucked on bigger bodies.
Compression that doesn't quit after three washes.
Cheap polyester stretches out, overheats, and loses its shape fast, especially under the constant stress of a larger frame. outsidezi's 80% Ionic Nylonholds its compression,stays breathable, and performs the same on wash 50 as it did on day 1.
FAQ

This compression shirt really works. I ordered my usual XL shirt size, and it fits great. It not only fine tunes my appearance, it helps my upper body feel firm. Keeps me from feeling loose and jiggly. Even inspires me to want to workout more. I'm buying another. Five Stars.

This is really great material, well done on quality. It is nice and snug, I'm an L at 6' 203 lbs with a belly and it's perfectly snug. Not so much you can't breath but it is true to fit. I wear this with tuck in shirts and it does good.

I have tried other undershirt and this is the best fitting and most supportive. The tanks cut into the skin but this sleeveless feels very comfortable. I have 2, XXL, and xl, xl definitely more compression and smoothes out my body a bit. Will buy more, oh and they also stay down and don't roll or ride up!
Anthony J Valvano
Extremely comfortable, I feel more confident when I wear it, doesn’t ride up, and it really helped my back pain because it supports you, also fast delivery, I recommend.

I had tried 2 other compression shirts before, although quite expansive, this one is much better, I will probably buy more for the summer.
Ed katz
Excellent. I bought four different brand shirts prior to this purchase. This brand is the best. It fits perfectly. I went with an extra large tall and I'm a XL. This is definitely a tall shirt with plenty of material below the waist. It is easy to wash and it is easy to pull over my head to put on. Some of the other brands that I bought required me to step into it like a skirt. I recommend this product to everybody. Additionally I purchased a package of three more of these compression shirts. I look great and feel good in the shirts. You won't regret this shirt.

This compression shirt exceeded my expectations. The fit is snug but comfortable, and it does exactly what it’s designed to do– provides firm compression in the chest and midsection without feeling restrictive. It stays in place throughout the day and doesn’t roll up, which is a big plus. The material feels durable yet breathable, making it easy to wear under regular clothes without being noticeable. It gives a nice confident, slim look as an undershirt and for workouts. After washing it didn’t shrink, it seems to wash well, mind you I’ve only washed it once. I liked it so much I ended up ordering more. They are a bit on the pricey side, but the quality and results make them worth it. If you’re looking for a reliable compression shirt for chest and tummy control, this one is definitely worth it.

I've been using outsidezi for a month now the less self conscious alone makes it worth it, plus the material is super comfortable cant complain.
