Define Jacket

The streamline fit means you'd fit in on the ski team. It's not so tight that you'd be mistaken for a bobsledder.

why we made this

We wanted to design a jacket that would protect us from refrigerator-chills without trapping the heat in like an oven. The mesh venting in the back and the moisture wicking fabric mean that we're not simmering in our own sweat by the time we've finished our run.

key features

  • fold your fingers into cozy cuffins
  • thumbholes keep distracting sleeves under the thumb
  • park that zip in the zipper garage before it scratches your chin
  • mesh venting in the back lets off steam
  • secure zippered pockets
  • dropped hem for more coverage in the rear
  • emergency hair ties to the rescue to keep your hair out of your face
  • chafe-resistant flat seams so you don't get rubbed the wrong way

tech specs

  • designed for: yoga, run
  • fabric(s): luon®
  • properties: four-way stretch, moisture wicking, preshrunk, chafe resistant, breathable
  • fit: fitted
  • length: mid-hip

Define Jacket 4.6 5 607 610
THE BEST! This jacket is one of my favorite clothes/jackets from lulu. It looks great on skinny and curvy person. It's very comfortable and hugs you in all the right places. Person who design this jacket thought about every detail that's why so many people love this! Therefore, I really don't understand why product like this, I would even say staple of your company is no longer available where jackets which even don't come close to this one are up for sale. That's very, very frustrating! Dear Lulu, please make a comeback for lovely Define Jacket. Everyone will appreciate very much. Thank you! April 18, 2013
Excellent One of my favorite quick jackets to throw on from Lulu! April 7, 2013
LOVE THIS JACKET!!!!! I've had this jacket for 2 months. Have worn and washed many times and it still looks great. Keep making this and I will buy it in every color. April 5, 2013
Easy to wear jacket Hi! I bought this jacket 6 months ago and it still is in PERFECT condition. I have never had a jacket that I wear this often stay in great shape for this long. I would definetely recomend this because it keeps you warm without over heating you, its soft, and it is cute as well! Hope this helps! March 31, 2013
One of my favorite articles of clothing I have this in the heathered grey material. It's one of my very favorite articles of clothing. I run in it, do errands in it.... Great fit and I love how the "cuffins" folds down. I tried on the Forme jacket, which is very similar and the cuff is not nearly as functional or comfortable. It looks like Lulu is discontinuing or limiting colors of this jacket and replacing it with the Forme. So disappointing, I was ready to by a 2nd Define jacket. March 27, 2013
Best jacket ever Great fit, attractive on, great functionality. Can't believe this is being discontinued! Do not like Forme jacket- quality and fit not as good, don't like the sleeves and material is thinner. Bring back the define!!!! March 25, 2013
I finally understand what the fuss is all about This jacket really is THAT great! I purchased apparently one of the last ones. According to some suggestions, I went a size up from my usually size 10 and bought the size 12 in black. I couldn't be happier with my purchase. I literally have worn this jacket every single day since I bought it. I wore it biking, I wore it walking the dog, and lounging around the house. It's comfy, the fit is amazing, and I love the long sleeves. If it's still available in your size - GET IT! NOW!! March 19, 2013
Best jacket out there!! I really love this Jacket I'm a figure skater and this jacket keeps me warm when I'm warming up and it fits your body really amazing :D I recommend this jacket for any one involve in sports!! :D March 12, 2013
Great style and comfort So far I've only gotten yoga tops and a pair of lulu crops, and I've been looking for a jacket for awhile. I chose this jacket after reading all the great reviews and seeing it on sale, even people selling it on ebay weren't this cheap! I'm usually a size 8 but after reading the reviews I decided to get a chance with the size 12 on sale. Love the style, perfect fit, wonderful flexible luon fabric. I haven't run outside with it yet, but just wearing it to yoga and the gym I'm very happy with it so far! March 4, 2013
Love this jacket, but... So, I love this jacket. You know you've found a winner when you feel über attractive in it! However, the FIRST time I washed this jacket (on gentle cycle, thank you), the zipper on one of the pockets came off!!! I'm still wearing the jacket because I like it so much, but, really, for what I paid, this jacket should NOT be falling apart already!!! March 2, 2013
