The Knit
A seamless structural knit, not a tight sheet of fabric. Here is what each zone is doing, what the yarn is, and why the tank sits flat instead of rolling at the edges.
The short version
- The shaping comes from knit direction, not from squeezing harder. Three zones pull in three different directions.
- Milk-silk polyester, about 180 g a tank, four-way stretch. Thin enough to disappear under an oxford.
- Seamless construction means no side seam to print through a shirt and no edge to dig in at the hem.
Built with direction
Chest yoke
A V of tighter knit across the chest and over both shoulders. It gives the fabric its direction and holds its shape through the day.
// feel: held, not squeezedCore channel
A ribbed channel of dotted knit down the center torso. It guides the smoothing downward, not across the belt line, so a shirt sits flat over it.
// feel: sits flat under a shirtSide lines
Curved segments down each side keep the knit creating a line instead of squeezing everywhere at once. Full range of motion stays yours.
// feel: moves with you
Milk-silk polyester. Thin, breathable, quick to dry.

No mystery fabric, no invented numbers. This is what the garment is.
Why the knit is the product
Most compression tops are a tube of tight fabric. Tension is the same everywhere, so the garment squeezes uniformly and the tissue it displaces goes up toward the collar and out over the hem. That is what creates a ridge across the chest and a roll at the waist, and both show through a shirt worse than the shape you were smoothing.
A structural knit varies its tension across the garment instead. Some zones are knitted tight, some open, and the transitions are gradual. The smoothing then has a direction: down the torso rather than outward at the edges. Because it is knitted rather than assembled, there is no side seam to print through a fitted shirt and no bonded panel to peel off after a few washes.
What milk silk is
Milk silk is the trade name for a fine polyester knit with a soft, faintly slick hand. It is thin, it wicks sweat away from skin, and it dries fast. It is not silk and it has nothing to do with dairy. What matters practically is the weight: around 180 g for a tank is thin enough to disappear under an oxford and substantial enough to hold a line.
The three zones
The chest yoke runs as a V across the chest and over both shoulders, giving the fabric its direction and holding shape through the day. The core channel is a ribbed run of dotted knit down the centre of the torso, which is what guides the smoothing downward rather than across your belt line. The side lines are curved segments down each flank, which stop the knit from turning into a general squeeze and keep your full range of motion.
The interactive breakdown above walks through each one. If you want the numbers instead, the spec sheet under it lists fabric, weight, stretch, collar and sizes with nothing invented.
Two panel treatments
The same garment ships in two finishes. The 806 line knits the structural panel in blue, so you can see the structure. The 807 line knits it in the body colour for a tonal read, which sits flatter under thin or pale shirts. Cut, fabric and fit are identical between them. Both are on the colorways page.
Making it last
The knit structure is the fabric, so it cannot crack or peel. What ages compression is heat: it relaxes the elastic fibre permanently. Cold wash, no softener, hang dry, and the tank holds its shape for years. The full method is in how to wash a compression shirt.

About the knit
What is a structural knit?
It is a single piece of fabric knitted at different tensions and stitch patterns in different places. The tighter areas hold, the looser areas breathe and stretch. Because it is one piece there are no panels stitched together, so nothing prints through your shirt.
What is milk-silk fabric?
Milk silk is the trade name for a fine polyester knit with a soft, slightly slick hand. It is thin, it wicks sweat, and it dries fast. It is a polyester, not a dairy product and not real silk.
Is a seamless tank better than a stitched one?
For wearing under clothes, yes. Stitched compression tops put a seam down the side of your ribs, and under a fitted shirt that line shows. Seamless knitting moves the structure into the fabric itself.
Does the panel wear out?
The knit structure is the fabric, so it cannot peel or crack the way a bonded panel does. What wears out compression is heat. Wash cold and hang dry and the stretch holds far longer.
