Take Back Control of Your Silhouette
You know the reflex: tugging at your shirt, crossing your arms in photos, holding your stomach in through a meeting. ShapeBoost™ was built so you stop thinking about it.
At its core, CompressionFit™ technology works across three distinct zones: it smooths your chest, pulls in your waist, and draws your shoulders back — the second you put it on, under any shirt. Seamless, breathable, completely invisible underneath. You stand taller without trying, your shirts finally fit the way they should, and nobody knows why.
How ShapeBoost™ Works
Four zones. One technology: CompressionFit.
Chest Zone — Targeted Hold
High-density knit flattens the chest and stops anything from showing through a thin shirt.
Core Zone — Midsection Control
The reinforced band pulls in your waist and smooths love handles — and it won't ride up during the day.
Back Zone — Posture Support
Tension panels draw your shoulders back and make you stand taller, without thinking about it.
Hem Zone — No-Roll Hold
The silicone-lined hem stays put from morning to night — it won't roll up over your belly, and it's long enough to tuck in.

Frequently Asked Questions
Who is ShapeBoost for?
Men who want a cleaner silhouette right away, not in six months. It flattens the chest, pulls in the waist, and straightens the shoulders — whether you train or not.
How does it actually work?
CompressionFit technology spreads compression across four separately calibrated zones: chest, core, back, and hem. The high-density knit holds tissue in place instead of just squeezing, which is why the chest stays flat where an ordinary tight tank does nothing.
How fast will I see results?
Immediately. Put it on in front of a mirror and the difference shows in seconds, under any shirt. Nothing to wait for, nothing to change in your routine.
Will it show under my clothes?
No. The edges are flat and there are no raised seams, so no lines show through a thin t-shirt. The neckline stays below an open collar.
Will I get too hot?
The fabric is lightweight and moisture-wicking. You'll sweat like you would in a regular t-shirt, without the smothering feel of thick compression gear, and the odor-resistant finish keeps the end of the day comfortable.
Does it roll up over the belly?
No — and it's the flaw that took us longest to fix. The extended hem stays put all day and is long enough to tuck in.
How do I pick my size?
Use our chart based on weight and waist, from S to 5XL. No need to size down. If you're between sizes, take the larger one — the compression is already built in.
What if the size is wrong?
Free exchange, no questions. Click the link in your confirmation email, we ship the right size with a return label.
How long does shipping take?
We ship your order within 24 hours. Delivery takes about 7 days, and you get a tracking number the moment it leaves our warehouse.
How do I wash it?
Machine wash cold on a gentle cycle. Hang dry — no dryer, that's what breaks down the compression.
What's it made of?
80% nylon, 20% spandex — same as most compression tanks. The difference isn't the material, it's the knit: four zones of varying density instead of one uniform fabric.
