Stretch & activewear: small-run US factories

Factories and studios whose own descriptions mention activewear, athleisure, leggings, swim or performance stretch work. Stretch fabrics need machines like flatlock and coverstitch, so this is a narrower group than general cut-and-sew.

Tags come from the words each factory uses about itself, so a missing tag doesn't mean a factory can't do the work. 14 listings. 10 state a minimum, and 1 says no minimum. The smallest stated number is 12 pieces.
