Knitted with 3D relief lines running the length of the arm, not printed on. A ribbed band at each end keeps them exactly where you put them.

Even hold

From just above the elbow to the shoulder, and never a pinch point.

Bands that stay

Ribbed top and bottom, so they hold their place and do not roll down.

Seamless knit

Thin, matte and breathable. Nothing shows through a sleeve.

90% polyamide, 10% elastane. Four-way stretch, one size, sold as a pair. There is no size to pick.

Position the top just below your shoulder seam and the bottom just above the elbow, so it does not fight the bend of your arm.

All day

Even pressure along the arm, so you can keep them on from morning to night.

Under anything

One smooth line under close-fitting sleeves, at work or out.

Easy care

Machine wash at 30 degrees. Reshape and air dry flat to keep the stretch.

How our 3D sleeves smooth the look of your arms

The effect shows the moment you put them on

The first look happens in the mirror, the day they arrive. This is the pace our customers report, and where the guarantee lands:

Arms held, instant lift

Sleeveless again

Smoother look, cleaner line

The cardigan stays home

Or your money back

The raised 3D knit runs from above the elbow to the shoulder and holds the skin flat instead of letting it move. A ribbed band at each end keeps the sleeve in place. The effect comes from wearing them, nothing to organize around it.

Nothing to book No appointment, no clinic, no waiting room.

Nothing to add to your day You put them on in the morning. That is it.

Nothing to lose 90 days to judge them on your own arms.

As long as you like. Most customers put them on in the morning and forget them until evening, under a blouse or on their own. There is no schedule to follow.

2h wearing them22h of your normal day

Upper arms soften for different reasons: weight changes, less muscle under the skin, age. The knit works on the surface, so what changes is the line under your clothes, not the skin itself. Here is how the usual options compare on what actually matters:

The honest part: on very loose skin after major weight loss, the sleeves smooth the line, they do not tighten it. That is why you get 90 days rather than a promise.

The compression is gentle rather than medical, which is why it suits skin that has softened with age or weight changes, and why any arm swelling deserves a professional opinion first.

Softener coats the fibers and flattens the 3D relief, the part doing the work. Machine wash at 86 F, dry flat, and the relief keeps its shape.

Machine wash at 30°C Turn them inside out Air dry flat or hanging

One size, the stretch does the adjusting, from a slim arm to a fuller one. If they do not sit right, returns are free for 30 days.
