PRODUCT DETAILS
Fabric: 80% nylon, 20% elastane
Available colours: Black, Grey, White
Type: Shaping tank with targeted compression
- Smooths your midsection the second you put it on

SIZE & FIT
Order the same size you buy in a t-shirt. Don't size down — the compression is in the knit, not in the size. Between two sizes, go up. Over 6'2", take one size up for length. Full measurements in inches in the size guide.
WASHING
Cold gentle cycle, hang dry. Never tumble dry — heat kills the elastane, and with it the compression.
90-DAY GUARANTEE
Wear it, wash it, wear it again. If it isn't for you within 90 days, one email and we refund it. No form, no phone call, no restocking fee.
FREE EXCHANGES
Wrong size? We ship the right one and you keep the first. No label, no post office, no waiting.
SAME MAN. BETTER FIT.
If you're tired of shirts that pull at the third button, and of layering a second t-shirt to hide it, TrueLine was built for you.
It's a seamless graduated knit: firmest across the midsection, lighter at the chest, with a bonded hem that doesn't roll. It smooths your silhouette the second you pull it on, holds you upright through the day, and disappears completely under a shirt.
No diets. No gym. Just a better fit.

BEFORE YOU BUY.
Will anyone be able to tell I'm wearing it?
No. It's grey with tonal knit panels and flat seams — there's no contrast colour to read through a shirt. The bright panels you've seen on other brands are exactly what shows.
Who is this actually for?
Men who want their shirts to sit better today, not after a twelve-week programme. If you've got a bit of a midsection and you're tired of baggy tops hiding it, this was built for you.
How does it work?
A seamless graduated knit — firmest across the midsection, lighter at the chest. It smooths your torso and holds you upright while you wear it. Put it on, put a shirt over it, look in the mirror. That's the whole mechanism.
How fast will I see a difference?
Immediately. There's no waiting period and nothing to stick to. If it doesn't do it in the mirror on day one, send it back.
What size should I get?
The same size you buy in a t-shirt. Don't size down — the compression is in the knit, not in the size. Between two sizes, go up. Over 6'2", take one size up for length.
What if I get the wrong size?
Email us and we ship the right one. You keep the first — nothing to send back, no label, no post office. And if it's still not for you, you have 90 days to get your money back.
Does it help me lose weight?
No, and we won't pretend otherwise. It changes how you look in your clothes while you're wearing it, and it keeps you upright. Anyone telling you a tank top burns fat is selling you something else.
How long does delivery take?
8 to 15 days. You get tracking the day it ships, plus an update at day 5 and day 10 whether or not anything has moved.
How do I wash it?
Cold gentle cycle, hang dry. Never tumble dry — heat kills the elastane, and with it the compression.
What's it made of?
80% nylon, 20% elastane. That's the figure here, on the label, and everywhere else on this site.
