We Design Leggings That Empower Your Brand
Leggings Manufacturing for Activewear Brands
Seam Apparel is a custom leggings manufacturer in the USA. We work with fitness brands, startups, yoga studios, and private labels to produce high-quality leggings for workouts, training, and everyday wear.
Our leggings are made using stretch fabrics like nylon-spandex and polyester blends. They are designed to move the body, stay comfortable, and last overtime. Most fabrics fall between 180–300 GSM, depending on whether you want something lightweight or more supportive.
We manage both small and large orders and work with brands across the USA and internationally.
Options for Compression
We offer the following based on your product:
- Light compression for everyday use
- Medium compression for working out
- High compression for working out at the gym
Simple to Scale
You can start with a small amount and make more as your brand grows.
Squat-Proof Quality
We check that the fabric isn’t see-through, even when you stretch or squat.
Easy to breathe and comfortable
Our fabrics are made to keep the person wearing them dry and comfortable.
Choices of fabric
The fabric you choose will change how the leggings feel and work.

Polyester-Spandex
Durable and holds color well. Best for printed or sublimated designs.
Seamless Fabrics
Fewer seams, more comfort, and a body-hugging fit.
