Silicone-Grip vs. Moisture-Activated Yoga Towels: What’s Better for Hot Yoga?
Not All “Grippy” Yoga Towels Grip the Same Way
Walk into almost any hot yoga class and you’ll see towels everywhere.
But underneath the similar shape and microfiber surface, yoga towels can behave very differently once you begin to move.
Some are designed so that the top surface becomes more tactile as moisture builds.
Others depend heavily on silicone, rubberized, or textured material underneath to resist movement against the yoga mat.
And some combine both approaches.
So when a yoga towel says non-slip, the more useful question is:
Where is the grip actually coming from?
Understanding that difference can help you choose a towel that matches the way you practice — particularly if you're someone who sweats heavily, moves dynamically, or finds yourself constantly readjusting your towel during class.
First: There Are Actually Two Types of Slipping
As we explored in our first article on the science of hot yoga towel grip, there are two separate surfaces at work during your practice.
Your hands and feet → the towel
This determines whether your body feels stable against the upper surface.
The towel → your yoga mat
This determines whether the entire towel stays where you put it.
Those are related problems, but they're not the same problem.
That's why a towel can feel grippy underneath your palms while still shifting across your mat.
Or it can stay beautifully anchored underneath while sweat changes how your hands interact with the surface above.
The best hot-yoga designs consider both.
What Is a Moisture-Activated Yoga Towel?
A moisture-activated or sweat-activated towel is designed so that traction at the upper surface increases as moisture interacts with the fabric.
That's why you may have heard the advice:
“Wet your towel before class.”
For certain towel constructions, that makes sense.
Manduka describes its eQua towel as a microfiber design that begins gripping when it comes into contact with sweat, while its Yogitoes line combines a moisture-activated textured upper surface with silicone nubs underneath. Manduka
Gaiam similarly recommends lightly spraying one of its grippy yoga towels with water before practice to enhance performance. Gaiam
The basic idea is simple:
Moisture changes the interaction between your skin and the textile surface.
As class becomes sweatier, the towel may begin providing greater traction underneath your hands and feet.
The Advantage of Moisture-Activated Grip
For someone who gets sweaty relatively quickly, this can work extremely well.
Once moisture is present, the upper surface may become increasingly useful for:
- sweaty palms
- damp feet
- heated Vinyasa
- Bikram-style practices
- high-intensity flows
And because microfiber is also managing moisture, the towel can serve two functions simultaneously:
absorb sweat + create a more usable practice surface.
But there is one obvious variable:
You need moisture.
If you're relatively dry at the beginning of class, traction may feel different than it does 30 minutes later.
That's why some practitioners pre-wet their towel.
What Is a Silicone-Grip Yoga Towel?
Silicone addresses a different problem.
Instead of relying primarily on moisture between your body and the top of the towel, silicone grip is placed on the underside to create friction between the towel and the mat.
Think about the moment you step from Downward Dog into Low Lunge.
Your hands push one direction.
Your foot travels another.
Your weight shifts forward.
Those movements transfer force through the fabric.
If there's very little resisting the towel underneath, the fabric itself can shift.
Silicone creates additional contact points designed to resist that movement.
That is the area Unalome chose to emphasize heavily.
Why Silicone Coverage Matters
Simply saying a yoga towel “has silicone” doesn't tell the whole story.
Two towels can technically contain silicone while having very different amounts of the underside dedicated to grip.
That's why Unalome focuses on coverage.
Our towels feature larger silicone nubs and 44% more silicone grip coverage, creating more gripping contact across the underside of the towel. Our towels also use heavier microfiber and measure 71 × 24 inches with a 3mm construction. Unalome Yoga
The concept is straightforward:
More of the towel is intentionally designed to interact with the mat underneath it.
And because that grip mechanism isn't dependent solely on your hands becoming sweaty first, the mat-side anchoring is there from the beginning of practice.
So, Which Is Better for Hot Yoga?
The most accurate answer is:
It depends on which kind of slipping you're trying to solve.
If your biggest issue is sweaty palms and feet sliding across the top surface, a moisture-responsive microfiber surface can be very useful.
If your biggest frustration is the towel itself shifting, folding, or bunching over your mat, strong underside grip becomes particularly important.
And if you sweat heavily?
You ideally want both effective moisture management and a towel that remains physically anchored underneath you.
That's why we don't think absorbency alone tells you whether a towel will perform well in hot yoga.
Silicone Grip vs. Moisture-Activated Grip at a Glance
| Moisture-Activated Surface | Silicone-Grip Backing | |
|---|---|---|
| Primary purpose | Traction between body + towel | Stability between towel + mat |
| Where grip occurs | Upper textile surface | Underside of towel |
| Needs moisture? | Typically performs increasingly as moisture builds | Mat-side grip does not depend on sweat |
| Helpful for | Sweaty hands and feet | Sliding, shifting and bunching |
| Pre-wetting | Can help some designs | Not required for silicone-to-mat contact |
| Ideal hot yoga setup | Moisture management + stable backing | Moisture management + substantial silicone coverage |
And importantly: these technologies aren't mutually exclusive.
Some towels combine them.
The real question is how effectively the entire towel has been designed as a system.
What About the Beginning of Class?
This is where the difference can become especially noticeable.
Your towel shouldn't only perform once you've reached peak sweat.
Think about the first ten minutes of a heated class.
You're warming up.
Your palms may still be relatively dry.
You're beginning Sun A.
You're moving repeatedly from Downward Dog into Plank, Chaturanga and Upward Dog.
If your towel depends heavily on moisture for traction, you may find yourself misting it first or waiting for sweat to build.
With a silicone-backed towel, the underside grip mechanism is already interacting with the mat beneath you.
That's one reason we've designed Unalome around substantial silicone coverage rather than expecting sweat alone to create stability.
And Then the Sweat Arrives
As class progresses, the problem changes.
Now moisture management becomes increasingly important.
This is where microfiber matters.
Unalome uses premium, absorbent, quick-drying microfiber designed to distribute moisture across the textile while the silicone underneath continues helping the towel remain anchored to the mat. Unalome Yoga
So instead of thinking about the towel as having one grip feature, think about it as a system:
microfiber manages the sweat above
silicone helps manage movement below
weight and dimensions help the entire towel remain stable
That combination is what we care about.
If You’re a Heavy Sweater, Look for These Five Things
If your hot-yoga towel regularly ends class looking like it went through a rainstorm, prioritize:
1. Substantial underside grip
Look beyond the phrase “non-slip” and see how the towel is actually anchored.
2. High-quality microfiber
The fabric needs to manage moisture without becoming an uncomfortable, waterlogged layer.
3. Full mat coverage
You don't want hands and feet repeatedly moving between towel and exposed mat.
4. Washability
A heavy-sweat yoga towel is going into the laundry. Frequently.
5. Durability
Grip that's great for three classes but deteriorates quickly isn't particularly useful.
It's exactly why commercial studio use has become such a meaningful product test for us.
Ritual Hot Yoga selected 1,000 custom Unalome towels for student use across its studios, where those towels will experience repeated sweaty classes and commercial laundering. Unalome Yoga
That kind of environment is difficult to fake.
Two Unalome Favorites Are Now $40
If you've been curious about trying a silicone-grip Unalome towel for yourself, two of our Grounded Collection designs are now available for $40 each.
Onyx — $40
Our Onyx Yoga Towel is the sleekest option in the collection: a primarily black design created around grounding and stability.
Underneath, it includes the same performance construction Unalome is known for:
44% more silicone grip coverage, larger silicone nubs, premium quick-drying microfiber, and 71 × 24-inch full-mat coverage. Unalome Yoga
For anyone who wants a minimal black hot-yoga towel without sacrificing performance, this is the one I'd point to.
Śānti — $40
For something softer and brighter, our Śānti Yoga Towel features a tranquil turquoise ombré design inspired by śānti — the Sanskrit word associated with peace and tranquility.
It carries the same 44% increased silicone coverage, heavier microfiber construction, full-mat dimensions, and machine-washable performance. Unalome Yoga
Onyx and Śānti are currently $40 each while available.
What If You Don't Practice Hot Yoga?
Silicone-backed towels aren't only useful in a 100-degree room.
Towel movement can happen anywhere there is:
- sweat
- dynamic transitions
- repeated weight shifting
- mat Pilates
- Yoga Sculpt
- power Vinyasa
- high-intensity mat work
In lower-sweat practices, silicone backing can arguably become even more relevant because you're not relying on moisture to activate additional traction at the top surface.
The towel still needs to stay where you placed it.
Do You Need to Wet an Unalome Towel Before Class?
No.
You can use an Unalome towel dry from the beginning of practice.
Because our mat-side stability comes from physical silicone contact underneath the towel, you don't need to spray it with water simply to activate that underside grip system.
As you begin sweating, the microfiber surface then helps manage the moisture produced during practice.
For someone who doesn't want another pre-class ritual to remember, that simplicity matters.
Roll out your mat.
Lay down your towel.
Practice.
The Best Grip Is the Grip You Stop Noticing
There's a reason we keep returning to this idea at Unalome:
Your equipment shouldn't become the focus of your yoga practice.
You shouldn't be halfway through Warrior II wondering whether your towel moved.
You shouldn't interrupt your flow to pull fabric back into place.
And ideally, you shouldn't have to think about the engineering underneath you at all.
That's our job.
Silicone coverage.
Microfiber.
Weight.
Dimensions.
Washability.
All of those technical decisions exist for one very non-technical reason:
so you can stay present.
Because ultimately, the best yoga towel isn't the one you think about the most.
It's the one you forget is there.

Frequently Asked Questions
Is silicone grip better than a moisture-activated yoga towel?
They solve slightly different problems. Moisture-activated traction helps increase grip between your hands or feet and the towel as sweat builds, while silicone backing helps resist movement between the towel and the yoga mat. For hot yoga, a design that manages moisture while also creating strong mat-side stability can offer advantages from both approaches.
Do silicone yoga towels need to be wet?
Silicone itself does not need sweat to create contact with the yoga mat underneath. Some towels may still have upper surfaces that behave differently when damp, but a silicone-backed towel's mat-side gripping mechanism isn't dependent on pre-wetting.
Why do some yoga towels tell you to spray them with water?
Certain microfiber or moisture-activated surfaces develop more traction once damp. Some manufacturers therefore recommend lightly misting the area beneath the hands and feet before class, particularly before natural sweat develops. Gaiam
Are silicone-backed yoga towels good for heavy sweaters?
They can be particularly useful because they address the movement of the entire towel against the mat while microfiber above manages sweat. Heavy sweaters should look for both effective moisture management and substantial mat-side grip.
What is the best yoga towel if mine keeps bunching?
If bunching or shifting is the main problem, prioritize a towel with substantial non-slip backing, appropriate weight, and full-mat dimensions rather than choosing solely based on absorbency.
What is the best black towel for hot yoga?
Unalome's Onyx Yoga Towel is a black, full-length hot-yoga towel featuring larger silicone nubs, 44% more silicone grip coverage, premium microfiber, and 71 × 24-inch dimensions. Unalome Yoga
Does Unalome have yoga towels under $50?
Yes. Onyx and Śānti are currently available for $40 each, giving shoppers access to the same Unalome silicone-grip construction at a lower price point.
