You know that feeling when you're halfway through a downward dog in a 95-degree hot yoga class, and suddenly your hands start sliding like you're on a slip-and-slide? It's the worst. It’s actually dangerous. I’ve spent way too much money over the last decade trying to find the "perfect" surface, and honestly, Lululemon The Mat 5mm is the only one that hasn't let me down when things get sweaty.
It’s heavy. It smells a bit weird at first. But it sticks.
Most people buy a yoga mat based on the color or how "squishy" it feels in the store. That’s a mistake. If you’re actually moving, flowing, and sweating, you need a technical tool, not a piece of foam. Lululemon basically changed the game when they dropped this specific design because they moved away from that cheap PVC stuff that most big-box retailers sell. They went for natural rubber and a polyurethane coating. It makes a massive difference.
The Sticky Truth About That Polyurethane Top Layer
Let’s talk about the grip. This is why people buy this mat. Most mats require a "break-in" period where you have to scrub them with sea salt or wait six months for the factory film to wear off. Not this one. Lululemon The Mat 5mm is grippy from the second you unroll it.
The top layer is made of polyurethane. It’s smooth to the touch, almost buttery, but it acts like a vacuum for your skin. When you get moisture on it—like, literal puddles of sweat—it actually gets grippier. It’s counterintuitive. You’d think wet plus smooth equals a disaster, but the material absorbs that moisture so you stay locked in place.
I’ve seen people at Wanderlust festivals or local CorePower studios trying to use those thick, pillowy mats. They look comfortable for about five minutes. Then, they start sliding. If you're doing a high-intensity vinyasa flow, you don't want "pillowy." You want stability. You want to know that when you jump back into a chaturanga, your hands aren't going to fly out from under you.
Why 5mm is the "Goldilocks" Thickness
Thickness matters more than you think.
You’ll see 3mm mats that are great for travel because they fold up into a tiny square. Then you have those massive 10mm foam "Pilates" mats that feel like a mattress. The Lululemon The Mat 5mm hits that perfect middle ground.

At five millimeters, you have enough cushion to protect your knees during a low lunge or a kneeling crescent moon. If you have sensitive joints, you know that sharp pain when you're on a hard hardwood floor with a thin mat. It sucks. But, you also don't want it too thick. If the mat is too soft, you lose your balance in standing poses like Tree or Warrior III. Your ankles have to work overtime just to stabilize because the "ground" is shifting under you.
Five millimeters gives you a solid base. You can still feel the floor, which is vital for proprioception—your body's ability to sense its position in space. It’s heavy, though. Don't let anyone tell you otherwise. Carrying this thing across town on the subway is basically a workout in itself. It weighs about 5.24 lbs (roughly 2.38 kg). If you’re walking three miles to the studio, you’re going to feel it in your shoulder.
The Natural Rubber Core and the "Smell" Issue
We have to be honest here: this mat stinks when you first get it.
Because the base is made from natural rubber (which is sustainably sourced, a nice plus), it has that distinct, "new tire" aroma. Some people hate it. I’ve heard friends say they had to leave theirs on a balcony for three days just to breathe. It does fade, though. Give it a week.
One thing most people get wrong is how they store it. Because it’s natural rubber, you should never, ever leave it in a hot car. The heat will bake the rubber, making it brittle and ruining that beautiful "rebound" feel. Also, keep it out of direct sunlight for long periods. UV rays are the enemy of natural rubber. If you treat it like a piece of high-end equipment rather than a rug, it’ll last you five years easily.
Real Talk: The Maintenance Struggle
If there is one "downside" to the Lululemon The Mat 5mm, it’s that it shows everything.
If you have lotion on your legs, you’ll see the streaks. If you have sweaty forehead marks from child’s pose, they’ll show up as dark spots. Because the polyurethane layer is porous (that’s how it sucks up the sweat), it also sucks up oils.

Don't panic.
You don't need those expensive, fancy essential oil sprays they sell at the front desk. In fact, those oils can actually clog the pores of the mat and make it less grippy over time. Honestly, just use a mixture of water and a tiny bit of lemon juice or white vinegar. Wipe it down after every class. Don't soak it. If you soak it, it’ll take forever to dry because that 5mm of rubber holds onto water like a sponge.
Comparing the Competition: Manduka vs. Lululemon
In the yoga world, there’s this eternal debate: Lululemon or Manduka?
It's basically the Mac vs. PC of the fitness world. The Manduka PRO is legendary for lasting forever—like, "pass it down to your grandkids" forever. But here’s the thing: the Manduka PRO is a closed-cell mat. It doesn't absorb sweat. This means if you do hot yoga on a Manduka without a towel, you will slide.
The Lululemon The Mat 5mm is an open-cell construction on the top. It’s designed for the sweat to go into the mat. For most modern practitioners who are doing dynamic, sweaty flows, the Lululemon mat is just more functional. You don't have to carry a separate yoga towel, which is one less thing to wash.
However, if you’re doing very gentle Hatha or Restorative yoga where you aren't breaking a sweat, the "stickiness" of the Lululemon mat might actually be annoying. It can sometimes feel like it’s grabbing your skin a bit too much during slow transitions.
Sustainability and What’s Inside
Lululemon uses an antimicrobial additive in the mat. This is actually pretty important. Since the mat is absorbing sweat, it could easily become a petri dish for bacteria and mold. The additive helps prevent that "gym bag" smell from taking over.

The rubber used is also FSC-certified (Forest Stewardship Council). This means it comes from forests that are managed to provide environmental, social, and economic benefits. It’s not a 100% "green" product—nothing with polyurethane really is—but it’s a far cry better than the cheap PVC mats that off-gas chemicals for years.
The Cost Factor: Is It Actually Worth $100+?
Look, $124 (or whatever the current price is in your region) is a lot of money for a rectangle of rubber. You can go to a discount store and find a mat for $15.
But here is the math.
If you go to yoga twice a week, that’s roughly 100 classes a year. A cheap mat will be shredded, stretched out, and smelling like a locker room within four months. You’ll buy three of them in a year. Or, you buy the Lululemon The Mat 5mm once, and it stays in prime condition for 2-3 years of heavy use.
From a "cost per wear" perspective, it’s a no-brainer. Plus, there’s the injury prevention aspect. If your hand slips in a handstand or a deep triangle pose, you’re looking at a pulled muscle or a tweaked wrist. That costs a lot more than a premium mat.

How to Get the Most Out of Your Investment
If you just bought one, or you’re about to, do these three things to make sure it doesn't end up in a landfill in six months:
- The "Unroll" Rule: When you get home from a sweaty class, do not leave your mat rolled up in your bag. Unroll it. Let it air dry completely. If you keep it rolled up wet, you’re asking for mildew, antimicrobial additive or not.
- Avoid the "Spray" Trap: Avoid heavy detergents or bleach. They will break down the polyurethane layer and make it peel.
- Flip It: Sometimes, if you're doing a lot of floor work or restorative stuff, you can actually use the "rubber" side up. It's less grippy but provides a different texture that feels more grounded.
Actionable Next Steps for Better Yoga Sessions
If you are struggling with grip or joint pain, your current gear is likely holding you back.
- Audit your current mat: Check for "pitting" (tiny chunks of foam missing) or if the surface feels "slick" even when dry. If so, it's time to upgrade.
- Test the weight: Go to a store and actually pick up the Lululemon The Mat 5mm. Make sure you're comfortable with the 5lb carry. If it’s too heavy, look at the 3mm version, but be prepared for less knee cushioning.
- Preparation: If you decide to buy, plan to "air it out" in a well-ventilated room for at least 48 hours before your first class to dissipate the natural rubber scent.
- Cleaning Kit: Mix a solution of 1 part white vinegar to 20 parts water in a spray bottle. It's the cheapest and most effective way to keep the surface clean without ruining the grip.
Yoga is about focus. It’s about the breath. It’s about being present. You can’t do any of that if you’re worried about your feet sliding out from under you. This mat removes the distraction. It just works. That’s why it’s been a bestseller for over a decade. It’s not just the logo—it’s the engineering. Regardless of your skill level, having a stable foundation is the quickest way to see progress in your practice. Keep it clean, keep it out of the sun, and it’ll be your favorite training partner for a long time.
