The compression layer
that has your back.

Graded 200gsm compression supports your back and core through the workday, holds your middle in smoother, and stands you taller — better posture and a cleaner shape, the second it's on. Nothing to strap, charge, or remember — it's a shirt.

Graded compression zones across the upper back
GradedCore™

The compression does the work.

Three things happen at once, and none of them ask anything of you.

01
Graded compression where it counts
Firmest across the upper back where the support matters, softer at the edges so it never digs in — and your shoulders settle back on their own.
02
A core band steadies your torso
Sits at the waist and gives your middle something to hold against, so the top half is not doing the work alone — and it gently compresses your midsection, so your shape looks cleaner under any shirt.
03
Mesh zones keep it wearable all day
Breathable panels where you actually sweat. This is the difference between a shirt you wear at 4pm and one you take off at 11am.
How it works in detail
Why buy from us

Three things we do differently.

Real fabric, not tissue

200gsm graded technical knit. The single loudest complaint in this category is shirts you can see your hand through — ours has weight you can feel in the box.

An honest guarantee

45 nights for a full refund. No store credit, no restocking fee, no photos of the tag.

Straightforward exchanges

Compression is unforgiving about size. Order the wrong one and we swap it for the right size.

Shirt
Actually thick enough

I have bought two of these off Amazon before and both were see through and stretched out in a month. This has real weight to it. Ordered a third after the first week so I have one for every day.

Tank
The one for dress shirts

I tried the shirt first and the sleeve seam showed slightly under a slim oxford. The tank is completely flat. This is the one if you wear a collar to work.

Long-Sleeve
Solved the winter gap

I stopped wearing the short sleeve version once it got cold because I was layering a hoodie over it and losing the effect. This is the same compression with sleeves so the layer under my jumper is doing the work.

Shirt
Good, snug the first few days

First two days it felt tight enough that I took it off after a few hours. By day four I stopped noticing. Would tell people to expect a break in period rather than judging it on day one.

Size guide

Stand like you mean it.

Put it on at 9am. Forget it's there. That's the whole system.
