Manduka eKO vs Retrospec Solana 1/2": Which One Should You Buy?

GearLab handed the eKO a perfect 10 for dry grip in its 2026 test, the best result of the 19 mats it measured, and placed it second overall at 87 out of 100. It is 7 pounds of closed-cell natural rubber for $114.

The Solana 1/2″ takes the opposite approach: 12.7 mm of soft NBR foam, 3 pounds, about $24.99, and 4.4 stars from roughly 9,200 Amazon buyers. One of these is a grip problem solved and one is a joint problem solved.

Natural rubber is tacky by nature. Manduka gives the eKO a textured closed-cell surface, so it grips through friction rather than by absorbing sweat the way an open-cell mat does. In a normal room that is as secure as a mat gets, which is what the perfect dry score reflects.

The limit shows up when you are genuinely dripping. Sweat has nowhere to go on a closed-cell surface, and GearLab’s 7 out of 10 wet puts the eKO mid-pack. The Solana’s ribbed foam has no answer at all once your palms are damp, which is normal for the material.

The eKO is dense and does not deflect, and it is heavy enough that it does not creep on a wood floor mid-flow. GearLab rated it 9 out of 10 for comfort and support, a measure of how well the surface holds you rather than how soft it feels.

At 12.7 mm the Solana compresses unevenly under one foot, so balance holds involve managing the mat as well as yourself. Retrospec calls this the steadier of its two Solanas, which is true relative to the 1″ version rather than relative to a yoga mat.

Kneeling. Half an inch of soft NBR is far kinder on a kneecap than 5 mm of dense rubber, and on tile or hardwood the difference is obvious in low lunges, table top and anything seated.

A folded blanket on the eKO gets you most of that padding exactly where you need it, without softening the parts of the mat you stand on. That is the route most people with sore knees end up taking, and it costs nothing.

Natural rubber comes out of the wrapper smelling strongly, and the eKO is no exception. It takes a couple of weeks of unrolled airing to settle, and some owners never entirely stop noticing it. The mat’s Amazon rating sits around 4.1 stars across roughly 700 ratings, modest for a mat that tests this well, and odor turns up repeatedly in the reviews.

The Solana has its own version of this. Retrospec tells buyers the NBR foam may release a harmless odor and asks them to air it for a day or two. That one fades faster.

Manduka specs the eKO at 7 pounds and GearLab measured 6.3, which is heavy for a 5 mm mat. That mass is part of why it stays planted, and it is a genuine consideration on a walk to a studio.

The Solana is 3 pounds with a nylon strap included. If the eKO’s weight is what puts you off, Manduka’s own eKO Lite and eKO Superlite are the lighter versions of the same idea.

This surprises people: Manduka’s lifetime guarantee applies to the PRO and PROlite lines, not the eKO. The eKO comes with a 30 day return window and nothing beyond it. It is a well-made mat, GearLab rated its materials 8 out of 10, but the paperwork does not back it the way a PRO’s does.

Retrospec warrants manufacturing defects for six months and takes returns within 30 days for unused product. Foam denting and rubber losing tack are both wear, so neither is covered by either policy.

The eKO is natural rubber, so anyone with a latex allergy should avoid it. That is not a technicality and it rules the mat out regardless of how well it scores.

NBR is nitrile butadiene rubber, a synthetic foam, and Retrospec lists the Solana as free of latex, BPA, phthalates and heavy metals. If allergy is a factor, the cheap mat wins this outright.

List prices are $114 and $24.99. Check the current price on the eKO at Amazon and the Solana at Amazon before deciding.

The eKO is not the cheapest way to get good grip, and it is one of the best. If $114 is more than you want to spend on rubber, our eKO vs Gaiam Premium comparison covers the budget end of the same question.

Buy the Manduka eKO if you want traction. It took the best dry grip score in GearLab’s 2026 field and finished second overall, and the things it asks of you are weight, a rubber smell for a fortnight, and no warranty.

Buy the Retrospec Solana 1/2″ if your knees are the reason you are shopping and your session is mostly on the ground. It is comfortable, light and cheap, and it is honest about being an exercise mat first.
