From relaxed silhouettes to detailed collar work, our custom oversized flannel shirts manufacturer network produces every style your brand needs - with your production team built in.

Oversized
Dropped shoulders and a roomy body for that effortlessly relaxed, streetwear-ready fit.

Crew neck
A collarless rounded neckline that gives flannel fabric a modern, pullover-style twist.

Collared

Puff sleeve

Your spec
Bring your own pattern or tech pack and we build to it.
A clean Cotton oversized flannel shirt with no branding is straightforward production. The stronger brief - and the more common one - layers in custom buttons, branded hardware, and construction detail that turns a basic silhouette into a private label piece. Our factory partners handle both ends, but the elaborate build is the norm for the brands we work with.
