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

The Solana 1/2″ is 12.7 mm thick against the PRO’s 6, weighs 3 pounds against 7.5, and costs about $24.99 against $144. It is also one of the best-selling exercise mats on Amazon, with roughly 9,200 ratings averaging 4.4 stars, so a lot of people are practicing on one right now.

This is the more interesting of Retrospec’s two Solanas for anyone doing yoga. The one inch version is too soft to stand on; half an inch is a real compromise between cushioning and stability. It is still soft compared with a proper yoga mat, and that is the trade this page is about.

At 12.7 mm your foot still sinks, just less. In a slow class you adapt to it without thinking. In a balance hold you notice: the surface compresses unevenly under one foot and you spend some of the pose correcting for the mat. Retrospec’s own framing is that the half inch is the steadier of its two, which is accurate as far as it goes.

The PRO does not compress at all. GearLab gave it a perfect 10 for comfort and support in its 2026 test, first of 19 mats overall at 91 out of 100. Standing on it feels like standing on a floor with a skin on it, which is exactly the point.

Half an inch of soft NBR foam is much kinder on a kneecap than 6 mm of dense PVC, and that is what Retrospec built the mat for. On tile or hardwood, in low lunges, table top or anything kneeling, the Solana is the more comfortable surface by a clear margin.

The counter is that a folded blanket on top of a PRO gets you most of the same padding exactly where you need it, without softening the rest of the mat. Plenty of people with sore knees settle there. If your practice is mostly gentle and floor-based, though, buying the padding built in makes more sense than working around it.

Sweat has nowhere to go on either mat. GearLab scored the PRO 9 out of 10 dry and 7 out of 10 wet, which was mid-pack for wet grip in a field of 19, and it lists slickness when really wet as one of the mat’s drawbacks. A new PRO is also slippery for a few weeks until it breaks in; Manduka now says regular use resolves that.

The Solana’s ribbed foam holds a dry bare foot fine and gives up under a damp palm. Nothing about $25 of NBR is going to solve sweaty-hand slipping. If that is your problem, the answer is natural rubber or an absorbent top, and our PRO vs Jade Harmony comparison covers the rubber option properly.

Manduka compresses PVC until 6 mm weighs 7.5 pounds. Retrospec fills 12.7 mm with light foam at 3. That density is what you are paying for and it decides three things at once: how the mat feels underfoot now, whether it stays put on a slick floor, and how many years before it flattens.

It also decides how the mat carries. GearLab lists heft as one of the PRO’s two main drawbacks, and 7.5 pounds is genuinely a lot on a walk to a studio. The Solana at 3 pounds with a nylon strap is easy to move around a house.

Retrospec tells buyers up front that the foam may release a harmless odor and asks them to unroll the mat and air it for a day or two before use. That is standard for NBR and worth planning around if the mat is going in a bedroom.

The PRO has a milder version of the same thing. Unroll it, leave it a week or two, and it goes. Neither mat should live in direct sunlight, which is hard on PVC and harder on foam.

The Solana dents. Soft NBR takes a permanent impression where your knees, elbows and heels land, usually inside a year of regular use, and the edges start to tear before the middle gives out. Retrospec warrants manufacturing defects for six months and takes returns within 30 days; neither of those covers wear.

The PRO mostly does not end. GearLab found testers still on the same mat after 20 years and scored it a perfect 10 for materials. Manduka’s lifetime guarantee is roughly ten years of regular use, one replacement, and proof of purchase from an authorized seller, with Amazon counting only when the mat is sold and shipped by Amazon itself.

List prices are $144 and $24.99. Check the current price on the PRO at Amazon and the Solana 1/2″ at Amazon.

Five Solanas cost about what one PRO costs, and you would go through several of them in the time one PRO lasts. That arithmetic only matters if you keep practicing for years. If you are two months in and unsure, $25 is a sensible amount to risk, and there are 6 mm mats around that price that behave more like yoga mats than the Solana does.

Buy the Retrospec Solana 1/2″ if padding is the problem you are solving, if your session is mostly on the floor, or if you want a cheap mat for a spare room. It cushions well, it comes with a strap, and it is honest about being an exercise mat first.

Buy the Manduka PRO if you practice yoga several times a week and want the surface to hold still. It won GearLab’s 2026 test at 91 out of 100 and it outlasts nearly everything. For something between the two, our PRO vs Manduka X comparison covers the cheaper end of the same brand.
