WHAT WE BUILD
From baggy to straight leg, our gym sweatpants manufacturers produce custom silhouettes matched to your brand's vision and tech pack specs.

Baggy
Relaxed, roomy fit through the hip and leg for maximum comfort during training and lounging.

Camo
Military-inspired camouflage patterns built into the fabric for a bold, streetwear-ready gym look.

Wide leg
Flared silhouette from thigh to hem offering unrestricted movement and a retro athletic aesthetic.

Oversized
Intentionally scaled-up proportions for a trend-forward, ultra-comfortable fit on and off the gym floor.

Straight leg
Clean, uniform width from knee to ankle delivering a classic, tailored activewear silhouette.

Your spec
Bring your own pattern or tech pack and we build to it.
A clean pair of gym sweatpants in polyester with no branding is straightforward factory work. A fully custom construction featuring sublimation for all-over dye print across every panel is where our production team delivers the most value. For most brands we work with, the elaborate end is the standard brief, not the exception.


START YOUR BRIEF
You don't need a finished design to begin. Bring a sketch, a reference gym sweatpants, a tech pack, or an AI-generated spec, and we develop it into a production-ready gym sweatpants.

A rough concept is enough to start a gym sweatpants brief.
