What is seamless manufacturing?

Knit as one piece, with zero side seams.

Seamless activewear is knit in a single piece on circular knitting machines — no side seams, no chafing, a second-skin fit with high stretch and recovery. It's the manufacturing method of choice for leggings, sports bras and yoga sets.

As a seamless manufacturer based in Turkey, Overfit Seamless controls every step of this process — from yarn selection to knitting, dyeing and quality control — in our own İstanbul facility.
