B Mat Everyday 4mm vs Lululemon The (Big) Mat 5mm: Which One Should You Buy?

The B Mat Everyday is 4 mm of dense rubber in a normal 71″ × 26″ mat, at $118. What you are buying is one of the grippiest surfaces anyone makes.

The Big Mat is 84″ × 28″, which is more floor than almost anything else on sale, with an absorbent polyurethane face over FSC-certified natural rubber, at $128. Since the prices are within ten dollars, this comes down entirely to whether you want grip or square footage.

GearLab rated the 4 mm b, halfmoon rubber 9 out of 10 for grip and called it among the grippiest mats it had used in either wet or dry conditions, with traction surviving sweat pooled under a tester’s hand. There is no break-in and no coating to wear off, because the grip is the material itself.

The Lululemon absorbs instead of shedding, which is a reasonable approach, and it is good rather than exceptional at it: GearLab scored the standard-size version of the same mat 6.5 out of 10 dry and 4.5 wet. Plenty of people use one in hot classes with a towel. If grip is the only criterion, this is not a close comparison.

One caveat the other way: the B Mat’s surface can be too grippy for styles built on sliding transitions, and GearLab’s testers ended up stepping between poses rather than gliding.

The Big Mat needs roughly seven feet by two and a half of clear floor. That rules out plenty of apartment living rooms once the furniture is accounted for, and it will not fit in most studio cubbies. On a shoulder strap, 84 inches of roll hangs well past your hip.

What it gives you is genuine. Nobody runs out of length, hands stay on the mat in a wide plank, and you can travel across it in a flow without stepping onto the floor. If you are tall or broad and have been working around a mat that is too small, that is the best ten dollars on this page.

The B Mat Everyday is about 4.1 pounds, and GearLab described it as portable by the standards of mats it beats on grip, rolling to roughly 3.5 to 4 inches across. It is a comfortable carry to a studio and it stores anywhere.

The Big Mat is 7.1 pounds and much bulkier. It is designed as a home mat and that is where it belongs. If you want Lululemon’s surface in something you can commute with, the standard Mat at 71″ × 26″ is the version to look at.

The Lululemon is the slightly more comfortable mat, at 5 mm to the B Mat’s 4, with a rubber base and PU face that has a little more give. GearLab scored the standard-size version 10 out of 10 for comfort and support, the top result in its test, which measures steadiness as much as softness.

Neither is a plush mat, and on tile a long kneeling sequence will find you on both. If cushion is the issue, b, halfmoon’s 6 mm B Mat Strong keeps the same grip with more material at $144.

The Big Mat is properly reversible: the polyurethane face for sweaty yoga and a textured rubber underside for a drier practice or general training. The standard version took GearLab’s Top Pick award for mixed fitness routines on the strength of that.

The B Mat is also usable either way up, but both faces are the same tacky rubber, so it is a convenience rather than two different surfaces. It is a yoga mat and does not pretend to be a cross-training one.

The B Mat is made in Spain from mostly natural rubber with some synthetic content, carries OEKO-TEX Standard 100, and b, halfmoon backs it for one year. Dense rubber wears slowly and there is nothing on the surface to degrade.

The Lululemon uses FSC-certified natural rubber with a PU face, and the face is its wear point: absorbent tops go shiny under heavy use. Lululemon covers it under its Quality Promise, which has no set term and is handled case by case. Both contain natural rubber, so neither is safe with a latex allergy, and both are ruined by sun.

$118 against $128. Neither is sold on Amazon. b, halfmoon sells the Everyday on its own site and Lululemon sells the Big Mat through lululemon.com and in stores, both close to list most of the year.

With ten dollars between them, price should not decide this at all. Decide on whether the mat stays in one room, and how much you sweat.

Get the B Mat Everyday if grip is what you are shopping for, or if the mat has to travel to a studio and fit in a cubby. It is lighter, easier to store, certified, and better than the Lululemon at the thing most people are actually trying to fix.

Get the Big Mat if you practice at home and you want the floor. It handles sweat well enough for most classes, the reversible underside covers general training, and 84 by 28 inches is a size almost nobody else offers. Just do not plan on carrying it far.
