The “Define Jacket” by Lululemon is made with their signature Nulu fabric, known for its buttery-soft texture, lightweight feel, and four-way stretch. The material is also sweat-wicking and breathable, ensuring all-day comfort.
This jacket is designed with a slim, body-hugging fit, so it tends to run slightly small. If you prefer a looser fit or plan to layer underneath, it’s recommended to size up.
