Bring Back Define Luon In More Colors!!!!!
This is hands-down, the best jacket that has ever existed. Don’t get me wrong. I appreciate and do purchase the Nulu Define jacket, but I wish Lululemon design team would bring back the Luon Define as well! This jacket offers more structure and helps hide imperfections in the body and offers a little more thickness. I miss the days when Lulu offered Define in a variety of different materials. It’s high time to bring it back!

We hear you on missing that thicker, more structured feel and having more fabric options to choose from. Consider your very enthusiastic vote for a Luon comeback officially cast.

White Luon Define Jacket
I ordered this jacket in white since i already have one other Luon define jacket in sunny coral. I do prefer this over the Nulu one but it’s just preference. I’ve had my other Luon define jacket for over 3 years and it’s in perfect condition. Looking forward for more colors in the Luon define jacket!
