Lululemon Define Jacket Vs. $39 Amazon Alternative

If you’re as chronically online as I am, you’ve likely seen videos of people showing off their Lululemon Define Jacket ($128). The jacket is a popular signifier of the “Range Rover Mom” aesthetic, but besides its trend factor, it’s also just a great lightweight layer for the transitional weather season. At one point, the Define jacket was so popular that the original TikTok craze caused sellouts and stock issues for months, but it’s now much more regularly available.

With a $128 price tag, I was sure there had to be a great alternative out there for less. So I was instantly sold when I saw a bunch of TikToks showing reviews of a $39 Amazon alternative.

I tried both of them out, side-by-side, to see where the differences lie. If you just want the short answer, it’s that the Lululemon jacket physically feels higher quality, but the look is basically identical. Read on for my in-depth comparison.

Lululemon Define Jacket vs. the Amazon lookalike

The two jackets look nearly identical, even down to the seam placement. The only real visual difference is the tiny logo on the zipper pull.

Admittedly, the Define Jacket fits like a glove.

When the jacket arrived, it looked tiny, but I was pleasantly surprised that the cottony soft fabric is super stretchy, and I had no problem fitting into my regular size 2. I styled the jacket with a tank top underneath, leggings, and trainers. Most of the time, it was just to wear casually for errands. I did wear it to the gym a handful of times, but got too hot to keep it on.

The jacket does have a real sculpting effect, which I was skeptical about after seeing so many people talk about it on TikTok. Thanks to the clever cut and curved front seams, it definitely makes my waist look more cinched.

When the jacket was due for a wash, I was a little frustrated to find that it could only be machine-washed cold, because I like to know that all my sweat and germs are cleaned off in a warmer wash. Luckily, it doesn’t need to be washed very often because of the sweat-wicking fabric.

After I got my Lululemon jacket, I saw multiple people come up on my FYP sharing that they’d found an affordable alternative on Amazon. I was immediately drawn in.

With over 76% of ratings at five stars on Amazon, I thought that the jacket was well worth a go for the price. I got mine for $39.99, which is less than half the price of the Lululemon jacket at $118. One thing I appreciated most was seeing how many colors and sizes the Amazon jacket came in — nearly twice as many as Lululemon — and the size range went up to XXL, whereas Lululemon only goes up to a numerical size 14.

The jacket arrived packed tightly in a vacuum-sealed bag. The bag itself was a little dusty, which wasn’t ideal, and it was hard to get the creases out of the jacket because it had been so tightly packed.

The quality difference is obvious in the way the jackets feel, but not how they look.

On first impressions, the jacket looked practically identical. The back vent was there, it had pockets on both the inside and outside, and it had the thumb holes that I found really useful on the Lululemon version.

I looked further at little details and noticed the Amazon jacket needs to be hand-washed, which is slightly inconvenient. And the jackets are both made of 87% nylon and 13% Lycra, but I instantly felt that the Amazon jacket didn’t hug me in the same way that the Lululemon one did. 

In terms of fit, the Lululemon Define Jacket is super figure-skimming, which also means it can hug parts of the body that you may prefer it didn’t. The jacket feels very solid, and the fabric feels luxe. In comparison, the Amazon jacket is soft but feels less sculpting and firm.

I prefer the quality of the Lululemon jacket, but the Amazon version is a great lookalike and has more color variety.

The Lululemon Define Jacket ranges in color from neutrals to pastel shades, all in the same texture and feel. Although there are a decent amount of color options, they are more frequently out of stock, especially in black and white. Every color is the same price.

The Amazon jacket has about two dozen different color options, including an animal print, cropped jackets, and fleece-lined versions. Their availability tends to vary based on size and flash sales.

The bottom line

The Amazon jacket is a great alternative to the Lululemon Define Jacket. It functions about the same and is a solid choice for those who don’t want to pay the brand-name price tag. The quality isn’t quite equal, but it’s a solid dupe nonetheless.
