When performance meets comfort… this is the Lululemon Define Jacket.

Lululemon’s fan-favorite Define Jacket, powered by Luon™ fabric, is ready for any adventure or downtime. This versatile piece delivers a feel-good fit that truly does it all.

Crafted from Lululemon’s signature Luon™ fabric, this jacket is cottony-soft, breathable, and sweat-wicking. The four-way stretch and added Lycra® provide the perfect balance of support and flexibility, while maintaining shape retention for long-lasting wear.

Designed with a slim fit that skims your body and sits just below the waistband, it offers moderate everyday coverage, perfect for any activity or casual wear.

Details that work as hard as you do:
Thumbholes and Cuffins™ keep the sleeves in place and the cold out. A locker loop makes it easy to hang, while the elastic zipper pull doubles as an emergency hair tie—just in case. Plus, zippered pockets offer secure storage, and a zipper garage ensures no chafing.

Available in White or Black, with a 2.0” heat-applied raised silicone patch embellishment on the upper left arm, this jacket combines performance, style, and versatility.

Whether you’re heading out or winding down, the Define Jacket has you covered.
