Why these rank the way they do

None of these match the $128 Define outright, but a couple come remarkably close on the things that actually define it — the buttery Luon-like hand-feel and that sculpting front-seamed cut.

CRZ Yoga Butterluxe Slim Fit Full Zip Running Jacket with Thumb Holes

It's the clear winner because it copies the parts that matter most: the same Butterluxe nylon-Lycra build mimics the Define's soft hand-feel, and the front panel seams plus slim cut recreate the sculpting silhouette. The softer collar and slightly longer length are minor deviations, not downgrades.

G Gradual Women's Zip Up Workout Jacket with Thumb Holes

Nails the slim zip-up look with thumbholes and pockets, but the thicker fabric doesn't replicate the smooth Luon-like feel — so it earns the budget crown rather than the top spot on fabric alone.

Locachy Women's Full Zip Slim Fit Yoga Running Workout Jacket

The viral BBL-jacket pick brings 4-way stretch and a flattering cut for the cheapest you'll spend here, but the noticeably lower fabric quality is exactly the trade-off you make at that price.

Spyder Women's Yoga Jacket

Lululemon naming it in their 2025 lawsuit tells you the silhouette is genuinely close and the fit is flattering — but it scores lower mostly on practicality: post-lawsuit stock is uncertain, so you may not be able to get it.

Jockey Ladies Full-Zip Yoga Jacket

Also lawsuit-cited and slimming, with the bonus of turning up at Marshalls/TJ Maxx, but it ranks at the bottom because the build visibly shows the price gap against the original.

Bottom line: Pay a little more for the CRZ if you want the genuine Butterluxe hand-feel and sculpting cut; grab the G Gradual or Locachy if you just want a cheap slim zip-up and can live with stiffer, lower-grade fabric.

About Lululemon Define Jacket & its dupes

The Lululemon Define Jacket is one of Lululemon's most recognizable pieces — known for its Luon fabric with a soft, slightly compressive handfeel, the curved front-panel seams that create a "snatched" hourglass shape, and a slim cropped fit with thumbholes. People want it for the sculpting silhouette as much as the comfort, which is exactly what makes it hard to dupe well: a good alternative needs to nail those panel seams and the four-way-stretch nylon-Lycra (or "Butterluxe") feel, not just the zip-up shape. The closest matches replicate the seaming and fabric; budget versions get the look but give up some of the buttery handfeel and finish.

How to choose a Lululemon Define Jacket dupe

If you care most about matching the Define's actual fabric and sculpting seams, the CRZ Yoga Butterluxe is the closest — same nylon-Lycra build and slim cut, just slightly longer with a softer collar. Shop on price and the viral fit if you don't mind lower fabric quality (Locachy's ~$27 "BBL jacket" and the lawsuit-named Costco Spyder/Jockey options around $22), or pick G Gradual / 90 Degree By Reflex if you want a sturdier, thicker workout jacket and don't need it to feel exactly Luon-soft. Remember pockets and thumbholes vary by model, so check the specific listing.

Lululemon Define Jacket dupe FAQ

Are Lululemon Define Jacket dupes actually worth it?

For the look and slim sculpting fit, yes — several alternatives genuinely capture the Define's curved front-panel seams and snatched silhouette for a fraction of the price. The honest trade-off is fabric and finish: the closest match (CRZ Yoga Butterluxe) gets very near the real handfeel, while sub-$30 options like Locachy feel noticeably thinner and the zippers and stitching show the price difference. If the buttery Luon feel and long-term durability matter most to you, the dupes won't fully replace the original.

What's the best Define Jacket dupe on Amazon?

CRZ Yoga's Butterluxe Slim Fit Full Zip is the most-cited Amazon match (~89%) because it uses the same nylon-Lycra Butterluxe build, has the front panel seams and a similarly slim cut, and includes thumb holes — it just runs slightly longer with a softer collar. If you want the viral budget pick instead, the Locachy full-zip (the ~$27 'BBL jacket') is popular for its shape, and G Gradual is a good middle option if you prefer thicker fabric.

Can I find a Define Jacket dupe at Costco?

Sometimes. Costco has carried Define-style yoga jackets from Spyder and Jockey for around $22 — both were actually named in Lululemon's July 2025 lawsuit. The catch is that Costco activewear (Spyder, Jockey, Danskin, Kirkland) is a seasonal in-store buy, not a permanent product, so availability varies by location and time of year, and the lawsuit may affect whether these specific jackets stay on shelves. The Jockey version also occasionally shows up at Marshalls and TJ Maxx.

Why was there a lawsuit over Define Jacket dupes?

In July 2025 Lululemon filed suit citing several lookalike products, including the Costco Spyder and Jockey yoga jackets, arguing they copied protected design elements. It's worth knowing as a shopper because it can affect availability — products named in a lawsuit may be pulled or restocked unpredictably, which is part of why the Costco finds in particular are hit-or-miss.
