Seamless garment manufacturer · İstanbul

Knitted in one piece.
Built to disappear under clothes.

We knit seamless underwear, thermal base layers, activewear and shapewear on Santoni circular machines in İstanbul — so there are no side seams to rub, ride up, or show through. We make them for our own labels, and under yours.

The difference

What “seamless” actually changes

Seamless knitting builds a garment as a single tube on a circular machine, so the body has no stitched side seams. As the machine knits, the yarn and stitch density shift — tighter where the piece needs to hold, looser where it needs to breathe.

That is why a good seamless piece supports without squeezing and stays put without elastic digging in. Fewer seams means fewer pressure points against the skin, less chafing through a day or a workout, and a cleaner line under fitted clothing.

  • 01

    No side seams

    Nothing to rub, twist, or leave a mark on the skin.

  • 02

    Zoned knit

    Support and breathability placed exactly where the body needs them.

  • 03

    Clean under clothing

    No bulky seam lines showing through a fitted top or leggings.

  • 04

    Less waste

    Knit close to shape, so far less fabric is cut away and thrown out.

Who you are working with

A knitting family, narrowed to one focus

Seamless Tekstil grows out of a family that has been knitting in Kağıthane, İstanbul since 1924. Our founder is an industrial engineer who joined the business in 2018 and shipped his first export the same year.

Over the next four years he built a B2B export operation that reached buyers across Europe — written and earned through the work itself, not bought with ads. Seamless is where we put that experience into one tight line: circular-knit garments that fit better because there is simply less in the way.

You deal with the people who run the machines, not a layer of agents between you and the floor. That keeps fittings honest, lead times realistic, and problems short.

Before you ask

Common questions

What products do you manufacture?

Seamless underwear for men and women, thermal base layers, activewear like leggings and sports tops, and shapewear — all knitted on Santoni seamless circular machines in İstanbul.

What is your minimum order quantity?

Production runs start from 500 pieces per style and colour. We can sample first, and discuss smaller first trials for new partners.

Do you offer private label and OEM?

Yes. We produce under your brand and can also develop new styles with you from a tech pack or a reference sample (ODM).

What does “seamless” actually mean?

The garment body is knitted as a single tube with no stitched side seams. Stitch density changes across the piece, so it supports without squeezing and sits cleaner against the skin and under clothing.

Which fabrics do you work with?

Polyamide and elastane, modal and micro-modal, cotton blends, recycled yarns, and merino wool for thermal pieces. Tell us the feel and performance you want and we will match the yarn.

Where do you ship?

We export from İstanbul across Europe and beyond. Share your destination and we will quote freight together with the order.
