The fabric was suitable for activewear, but it felt a bit on the cheaper side. Considering the price point, it might be acceptable, but there is definitely room for improvement in quality.
Also, the stitching was not up to activewear standards. It seemed more like regular trouser stitching, whereas activewear usually requires more flexible and stretch-friendly stitching to ensure comfort and avoid irritation during movement.
I hope this feedback helps you improve.
