Quality Analysis 70/100
This lululemon sports bra, crafted from a blend of nylon and LYCRA® for shape retention, is designed for light support and yoga, suggesting it's not intended for high-impact, high-abrasion activities. The "mid-weight" fabric and "machine wash" care indicate reasonable everyday durability for its intended use.
Comfort Assessment 100/100
This sports bra is designed for ultimate comfort, featuring "buttery" Nulu™ fabric with LYCRA® for shape retention and an "unrestricted" feel. Its sweat-wicking and stretchy properties, along with COOLMAX Polyester® in the lining, ensure you stay dry and comfortable during any activity.
Sustainability Impact 60/100
This sports bra is made from conventional fossil-fuel synthetics like nylon and polyester, with no mention of recycled content, which negatively impacts its sustainability score.
