What our CUSTOMERS say


Leeline Sourcing is my favorite activewear manufacturer. I run a female sportswear store and order a bunch of sports bras and yoga pants monthly. And I can say that there is no brand that rivals these guys’ quality and professionalism. Their customer service team is super friendly too. They are the best manufacturer of sportswear, hands down!!

And that’s been my best business decision EVER! Their product quality is just on another level. I finally found a reliable sports apparel maker I can trust.
