Seamless Activewear Manufacturer in Turkey
Overfit Seamless is a seamless manufacturer based in İstanbul, Turkey, producing premium tights, leggings, sets and sports bras from yarn to finished garment — A to Z, in-house. We are a private-label activewear manufacturer for brands across the USA and Europe.
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.
