Synonymous with the global wellness and athleisure phenomenon, lululemon delivers its legendary design ethos in this Chicago Cubs collaboration. The celebrated Define Jacket silhouette is engineered from the brand's proprietary Luon™ fabric — a cottony-soft material that is both sweat-wicking and exceptionally breathable. Integrated Lycra® fibre ensures phenomenal four-way stretch and shape retention, creating a sculpted profile that contours your form perfectly.
From a downtown coffee run to cheering in the stands, this versatile piece is an absolute grand slam for any high-style rotation.
