It happened slowly, then all at once. You’re at the gym, or maybe just grabbing an overpriced oat milk latte, and there it is—that distinctive feline pattern wrapped around a sleek, athletic silhouette. We are talking about the leopard print define jacket. It’s everywhere. Honestly, if you’d told me five years ago that we’d be pairing high-performance technical gear with a print once reserved for 80s rockstars and Italian socialites, I might have rolled my eyes. But here we are.
It works.
The Define Jacket, specifically the one popularized by Lululemon, has been a staple for over a decade because of its "snatched" fit and Luon or Nulu fabric. But the leopard print version? That’s a different beast entirely. It sits at this weird, perfect intersection of "I just ran three miles" and "I’m meeting the girls for brunch and I actually tried today." It’s bold. It’s a bit loud. Yet, somehow, it functions as a neutral in a modern wardrobe.
The Psychology of the Print
Why are we so obsessed with putting spots on technical gear? Evolutionarily, leopard print was about camouflage, but in the concrete jungle of a Pilates studio, it’s about visibility. It signals confidence. When you wear a leopard print define jacket, you aren't trying to blend into the drywall.
Fashion historians often point out that leopard print cycles back into style every time the economy gets a bit chaotic or people feel a need for "power dressing." It’s primal. In the context of activewear, it breaks the monotony of the "sad beige" trend that dominated the early 2020s. People got bored. We spent years wearing matching sets in colors like "sand," "clay," and "dust." Boring. The sudden resurgence of animal prints in the Define silhouette is a direct rebellion against that minimalism.
It's also about the "Define" fit itself. The jacket is famous for its back venting and the way the seams curve inward to accentuate the waist. When you add a busy pattern like leopard, it actually creates an optical illusion. The spots break up the light, often masking sweat marks or those little bumps that thinner leggings might show. It’s functional vanity.
Spotting the Real Deal: Fabric Matters
Not all leopard prints are created equal. If you’re looking at a leopard print define jacket, you’re likely looking at one of three main fabrications, and choosing the wrong one is a mistake you’ll feel during your first workout.
Nulu vs. Luon vs. Everlux. If you want that buttery, "second skin" feel, you’re looking for Nulu. This is what the Align line is made of. It’s soft. Extremely soft. But—and this is a big "but"—it pilled like crazy in earlier iterations. Modern versions are better, but if you’re wearing a backpack over your leopard print Nulu jacket, the friction will eventually cause fuzz balls.
Then there’s Luon. This is the OG. It’s thicker, more "hugged," and feels more like a traditional jacket. It holds the leopard print well because the fabric is dense, so the white underside of the fabric doesn't "grin" through when the material stretches over your shoulders.
Finally, Everlux is the dark horse. It’s designed for high sweat. It’s cool to the touch. If you’re actually planning on doing a HIIT workout in your leopard print, this is the one. It dries fast. Like, really fast.

How to Style It Without Looking Like a Costume
This is where people get tripped up. There’s a fine line between "athleisure icon" and "Peg Bundy at the gym."
The trick is balance.
If you’re wearing the leopard print define jacket, keep everything else incredibly understated. Pair it with black high-waisted leggings. Simple. The black in the leggings pulls out the black spots in the jacket, creating a cohesive line. If you want to get risky, you can do a dark forest green or even a deep navy, but avoid pairing it with other prints. Don't do it. No floral leggings. No camo. Just... no.
Shoes matter too. A clean, white chunky trainer like the New Balance 530 or a sleek Hoka Bondi 8 keeps the look grounded in "sporty" territory. If you wear it with UGGs, you’re leaning into the 2010s "Cheetah Girl" aesthetic, which is fine if that’s your vibe, but it’s less "chic" and more "errands at Target."
The "Scandi-Girl" Approach
Lately, I've seen influencers in Copenhagen and Stockholm styling the define jacket under a heavy wool overcoat. It’s a genius move. The leopard collar peeks out from the lapels of a tan or charcoal coat, adding a pop of texture to a cold-weather outfit. It makes the technical gear look like a high-fashion mid-layer.

Common Misconceptions About the Define Fit
People often say the Define Jacket runs small.
Kinda.
It’s designed to be "skin tight." That’s the point. The "Define" name refers to the jacket defining your silhouette. If you buy your "true size," expect it to feel like a corset made of yoga pants. If you want to actually zip it up comfortably over a tank top without feeling like you’re being squeezed, almost everyone recommends sizing up by one.
Another myth: "The print will fade."
High-quality technical brands use sublimation printing for these patterns. The ink is essentially turned into a gas and bonded to the fibers. It’s not just sitting on top like a cheap screen print. Your leopard print define jacket should stay vibrant for years, provided you don't commit the ultimate sin: putting it in the dryer.
Heat is the enemy of Lycra. If you dry your jacket, the tiny elastic fibers snap. Over time, your jacket will lose its "snap-back" ability and start to look saggy. Hang dry only. Always.
Why Collectors Chase Specific Leopard Drops
There’s a weird secondary market for these jackets. Not all leopard prints are the same shade. You have "Formation Camo Deep Coal Multi" (which is basically a leopard/camo hybrid), "Leopard Camo Blue Nile," and the classic "Leopard Grain."
Collectors on sites like Poshmark and Depop will pay a premium for the "neutral" leopard—the ones that use tan, cream, and black. Why? Because the "snow leopard" versions (grey and white) or the colorful versions are harder to style. The classic tan leopard is the "Holy Grail." It’s the one that looks expensive.
If you find a vintage or "gently used" version, check the thumbholes. The Define jacket is famous for its "Cuffins"—little fold-over flaps that cover your hands when it’s cold. If those are frayed, the jacket has been through the ringer.
Real-World Performance: Is it actually for the gym?
Honestly, most people don't wear the leopard print define jacket for heavy lifting. It’s a "warm-up" jacket. You wear it to the gym, you take it off when the heart rate gets up, and you put it back on to leave.

The Nulu fabric isn't great for barbell work because the knurling on the bar will shredded the fabric. However, for walking, Pilates, or yoga, it’s perfect. The back vent actually works. If you’re a runner, the zip pockets are a lifesaver for keys, though a modern iPhone Pro Max is going to feel like a brick bouncing against your hip.
Actionable Steps for Your Next Purchase
Before you drop $120+ on a new jacket, do this:
- Check the Fabric Content: Look for at least 15-20% Lycra or elastane. Anything less and it won't hold its shape after three washes.
- The "Squat Test" for Arms: Put the jacket on, zip it up, and hug yourself. If it feels like the back seams are going to pop, go up a size. You need range of motion.
- Color Match: Hold the jacket against your most-worn leggings. If the "tan" in the leopard is too yellow and your leggings are a "cool" black, it might look slightly off. Aim for a neutral-toned leopard.
- Invert It: Turn the jacket inside out. High-quality leopard prints should have clean stitching on the interior. If you see loose threads near the zipper track, it’s a pass.
- Wash Cold: When you finally get it home, wash it on cold, inside out, with other synthetic materials. Avoid washing it with cotton towels, or you’ll end up with white lint stuck to your beautiful leopard spots.
The leopard print define jacket isn't just a trend; it's a statement of intent. It says you're serious about your movement but not so serious that you can't have a little bit of fun with your gear. It's a classic for a reason. Just don't put it in the dryer. Seriously.
