IUGA PU Mat vs Retrospec Solana 1": Which One Should You Buy?

The IUGA is 5 mm of sweat-absorbing polyurethane on a natural rubber base, lists at $66.99, and holds GearLab’s Best Value Upgrade award. The Retrospec Solana 1″ is an inch-thick slab of NBR foam, five times as deep, for $39.99.

These are two different kinds of mat, $27 apart. The IUGA is built to keep your hands planted in a sweaty class. The Solana is built to keep your knees off a hard floor. Most people already know which of those they need more.

GearLab scored the IUGA 75 out of 100, eighth of 19 in its March 2026 roundup: 8 for comfort and support, 7 for materials, 8 for care and cleaning, and grip of 8 dry and 7 wet. It sees the mat as an upgrade for a weekly or twice-weekly practice rather than a daily one.

GearLab doesn’t test Retrospec. The Solana 1″ has volume instead: about 15,000 Amazon ratings at 4.5 stars, and it ranked fourth among Amazon’s best-selling yoga mats when we checked. That says owners are happy with what they bought, mostly as a floor mat. It says little about grip.

The IUGA’s Amazon record is smaller, 4.4 stars from about 2,900 ratings, and its review summary agrees with the lab on the point that matters most: 604 of 703 grip mentions are positive.

Polyurethane drinks in a little moisture, so the IUGA’s traction holds as your hands warm up. GearLab says it stays grippy even when wet and calls it a favorite among sweaty yogis, and 106 of the 119 hot yoga mentions in its Amazon summary are positive.

The Solana grips with ribs pressed into closed-cell foam. Dry, they give your hands something to push against. Wet, the foam can’t absorb anything, so your palms skid across the ribs. Retrospec sells the mat for flows, Pilates, stretching and floor workouts, and hot yoga isn’t on the list.

Retrospec sells the Solana as pressure relief for your joints, and owners like what they get: 919 of the 1,092 thickness mentions in Amazon’s summary are positive. For physio, core work or stretching on tile, an inch of foam beats any 5 mm mat.

GearLab rated the IUGA’s cushion 8 out of 10 and says it protects knees on hard floors, which is true for a yoga mat. It still has a fifth of the Solana’s depth. For long restorative holds, GearLab suggests pairing a sturdier mat with a blanket or a second mat, which works well with the IUGA.

Put all your weight on one foot and an inch of soft NBR gives unevenly beneath it, so your ankle spends tree pose correcting. That’s simply what that much foam does. Retrospec’s copy still calls the Solana stabilizing, while some owners in Amazon’s summary say they struggle to balance on it.

GearLab says the IUGA is firm enough for strength and balance poses, single-leg ones included. The catch it mentions is that at 2.1 pounds, the mat can wrinkle slightly in the middle if you’re heavy on your feet.

The IUGA is 72″ × 26″ and 2.1 pounds, which GearLab’s scale confirmed. The Solana is 72″ × 24″ and 4 pounds. The IUGA is the roomier mat and still weighs about half as much.

Rolled up, the gap grows. The IUGA packs small and comes with an adjustable strap, while an inch of foam rolls bulky however carefully you do it. Retrospec includes a nylon carrying strap too, though Amazon’s review summary is mostly negative on it, with some owners saying theirs wasn’t in the box. GearLab lists the IUGA among its first picks for practicing outdoors.

The IUGA’s base is natural rubber, so it isn’t a mat for a latex allergy even though you touch only polyurethane. IUGA says the mat is SGS certified and odorless. GearLab lists a strong initial smell among its cons, and odor mentions on Amazon lean negative, 108 of 189.

NBR is a synthetic foam with no natural rubber in it, and Retrospec adds that the Solana contains no phthalates or heavy metals. It suggests airing a new one out for a day or two.

GearLab says the IUGA’s materials outlast its price, yet its cons still include a short lifespan, and it warns that rough ground like pavement wears the open-cell top down sooner. Anyone practicing daily, or wanting five years or more, gets steered to the Manduka PRO or Jade Harmony 2.0.

The Solana’s weak spot is tearing. About two thirds of the durability mentions in its Amazon summary are negative, and soft foam also takes a permanent set where knees and heels press. Retrospec covers defects for six months; IUGA offers no warranty. Neither covers ordinary wear.

List prices are $66.99 and $39.99. Amazon prices each color on its own, so look up your color on the IUGA listing and the Solana 1″ listing before ordering. The IUGA comes in five colorways at last count; the Solana in 13 colorways at last count.

Direct returns are narrow on both. IUGA allows 45 days but you pay return shipping, and Retrospec takes back only unused mats in the original packaging within 30 days. Amazon orders follow Amazon’s policy.

For half the foam, see Solana 1″ vs 1/2″; IUGA vs Solana 1/2″ puts that thinner Solana against this IUGA.

Buy the IUGA if you’re doing yoga, especially flowing or sweaty classes. It grips wet, it’s steady on one foot, it’s wider and it weighs about half as much, and an independent test ranked it eighth of 19. Expect a few years from it, not a decade.

Buy the Solana 1″ if padding is the point: stretching, physio, core work, or a gentle practice that rarely leaves the floor. It’s $27 cheaper, latex-free and far softer, but damp hands slide on it and one-legged poses feel unsteady.
