I'm looking to stock some durable activewear, specifically non-toxic sports bras, leggings, racerback tanks, and bike shorts. It's important that these items can handle intense strength training and maintain their shape, so I prefer a mixed fiber composition with at least 8% spandex or more. Could you provide details on the fabric compositions you offer for durable activewear that can withstand stretching? I'm keen on ensuring the quality meets our performance standards while being mindful of sustainability. Thanks!
