Who sells activewear and gym wear
Built for how activewear and gym wear actually sell
Fitness brands and gyms sell activewear in short drops and small batches. A run club wants forty tees in its own pattern. A gym wants merch for the front counter.
The customizer does the pattern work that makes activewear look good: all-over prints, colour on mesh panels, a logo that catches headlights. Each order arrives with print files cut to the panels.

Questions
What buyers ask us
Do you support all-over sublimation prints?
Yes. The pattern covers every panel of the 3D model, and the order comes out as a print file per panel at full size, ready for the heat press.
Can a gym sell custom merch to its members?
Yes. Set up a design with the gym's logo and share the link. Members add their name and size and pay on your store.
How quickly can a gym tee customizer go live?
If the product is already in our catalogue of 4,000+, there's no modelling to wait for. You choose the options, connect your store, which takes about five minutes, and publish. A product we model from scratch takes longer, and we'll tell you how long before you commit.
We already use another customizer. Can we move?
Yes, and it costs nothing. Our team moves your products, options, fonts and artwork across, and your current setup keeps selling until the new one is live.
