Seamless vs Cut and Sew Activewear: Which Is Right for Your Brand?
Seamless and cut and sew are the two main ways activewear is made, and the choice affects fit, design options, sizes, MOQ and cost. We run both routes in our Guangzhou factory, so this guide compares them from the production side.
- Choose seamless for close-fitting, body-mapped styles with knitted-in rib, mesh or compression zones, in runs of 500+ pieces per color.
- Choose cut and sew for pockets, panels, prints, a wider fabric choice, plus sizes and smaller first orders from 200 pieces per color.
- Combine both in one collection when it suits your range.
How seamless activewear is made
Seamless garments are knitted in a tube on circular knitting machines. We knit on 30 Santoni machines in our own factory. Instead of sewing panels together, the machine follows a knitting program that builds the shape and texture directly into the garment: denser compression zones, rib textures, mesh for ventilation and contour lines.
After knitting, each piece follows its finishing route: dyeing or setting, then any assembly or finishing seams the design needs, such as a waistband or straps. Our seamless styles are mainly knitted from 90% nylon / 10% spandex.
How cut and sew activewear is made
Cut and sew starts with fabric. The fabric is spread, cut into pattern pieces and sewn together, usually with flatlock or coverstitch seams that stay flat and stretch with the body. Because each panel is cut separately, you can combine fabrics, add pockets, contrast panels and binding, and use printed fabrics.
We sew on hanging-system production lines and work with a wide range of knit fabrics, including 75/25, 78/22 and 70/30 nylon-spandex, 80/20 polyester-spandex and GRS-certified recycled fabrics.

Does seamless activewear have seams?
Usually a few. “Seamless” means the main body is knitted in one piece without side seams, which reduces chafing and gives a smooth look. Many seamless garments still have assembly or finishing seams, for example where a waistband is attached or straps are finished. We confirm the required sewing steps for each design during sampling.
When to choose seamless
- You want close-fitting seamless leggings, bras or tanks with knitted-in compression, rib or mesh zones.
- Your design relies on texture and body mapping rather than pockets or prints.
- Your quantity reaches 500 pieces per style and color.
- Your size range is XS–XL.
When to choose cut and sew
- You need pockets, contrast panels, zips or color blocking.
- You want a specific fabric, such as a soft 75/25 nylon-spandex or a recycled fabric, or custom prints.
- You offer plus sizes up to 3XL.
- Your first order is smaller, from 200 pieces per style and color. See Cut & Sew.
Cost and MOQ
Seamless styles need a knitting program, machine setup and test knitting before bulk production. Those setup costs are the same for small and large orders, which is why the MOQ is 500 pieces per style and color. Cut and sew needs less setup per style, so it starts from 200 pieces. Which route gives better value depends on your design and quantity. Our MOQ guide and leggings cost guide explain both in more detail.
Sampling works the same way for both routes: samples take 12–15 days and cost US$10–15 per style, refunded once your bulk order reaches the MOQ, and bulk production takes about 35 days after sample approval.
Can you combine both in one collection?
Yes, and many brands do. A common combination is seamless sports bras or tanks with cut and sew leggings that have pockets, or seamless leggings with a cut and sew jacket. Each style follows the MOQ of its own route. Because seamless yarn and cut and sew fabric are dyed differently, colors are checked side by side on the samples. See how we develop matching sets.
Frequently asked questions
What is the difference between seamless and cut and sew activewear?
Seamless activewear is knitted to shape on circular knitting machines, with rib, mesh and compression zones knitted into the fabric. Cut and sew activewear is cut from fabric and sewn together, which allows pockets, panels, prints and a wider choice of fabrics.
Does seamless activewear have seams?
It has few or no side seams, but it can still include assembly or finishing seams, for example at the waistband or straps. The required sewing steps are confirmed for each design.
Is seamless activewear better than cut and sew?
Neither is better in general. Seamless suits close-fitting, body-mapped styles in larger runs. Cut and sew suits detailed designs, prints, plus sizes and smaller first orders.
Why does seamless activewear have a higher MOQ?
Each seamless style needs a knitting program, machine setup and test knitting, and yarn is prepared for each color. These setup costs are the same for small and large orders, so seamless styles start from 500 pieces per style, per color, compared with 200 for cut and sew.
Can seamless activewear be made in plus sizes?
Our seamless styles are made in sizes XS–XL. Cut and sew styles can be made in plus sizes up to 3XL.
Can I combine seamless and cut and sew styles in one collection?
Yes. Many brands pair seamless bras or tops with cut and sew leggings, or the other way round. Each style follows the MOQ of its own route, and colors are checked across both on the samples.
