This is a guide to what is actually happening on the surface, why the towel solves about two thirds of the problem and not the rest, and what the clothing you wear does about the remaining third that most people never think to look...
There is a particular moment in a Pilates class that nobody enjoys: the moment the instructor tells you to take your towel to the wipe-down station and wipe the mat down before you start. On a busy afternoon in a room where the mats are stacked and handed out, this is the moment you find out something about the studio. The mat is not yours. It was on the last person, and the person before them, and the person before that, and nobody wiped it between.
There is an obvious response, which is to bring your own towel and put it over the mat before you lie on it. Most people do this. It works for the part of the surface your torso touches, and it does nothing for the part your hands touch, your knees press into, or your forearms rest on when you come down to the mat for a plank. If you are the kind of person who thinks about this at all, you have probably noticed that the towel is the wrong shape for the problem, and that it moves.
This is a guide to what is actually happening on the surface, why the towel solves about two thirds of the problem and not the rest, and what the clothing you wear does about the remaining third that most people never think to look at.
The part of the mat you never touch with a towel
A studio mat is a closed-cell foam surface with a slightly textured or smooth top. It is designed to grip slightly so that your hands do not slide in a downward dog, and that grip is the entire reason it is a good practice surface. The problem with a surface designed to grip is that it holds whatever is on it. Between uses, a mat picks up skin cells, sweat dried onto the top layer, and the residue of whatever cleaning solution the studio uses, which is often a quaternary ammonium compound that is fine on a hard floor and not designed to be left on a soft porous surface.
Now think about which parts of the mat get wiped, and which do not. A folded towel placed at the centre of the mat covers the area between your hip bones and your shoulders, which for most of a supine sequence is the largest single patch of contact. It does not cover the palms of the hands in a plank, the knees in a kneeling stretch, the forearms in a low lunge, or the feet when you are in a bridge with your shoulders on the floor and your soles planted. Those are all smaller patches, but they are the ones that carry most of the pressure, because they are load-bearing rather than resting.
The towel also has a behaviour under load that people rarely anticipate. A thin cotton towel on a grippy mat does not stay flat. It bunches under the knees, it slides across the surface when you push off, and it ends up rolled into a ridge under your sacrum, which is the single worst place to have a small ridge pressing on you for forty minutes. A towel that is spread out flat is doing its job. A towel that is folded is doing half a job and adding a new small problem in the middle of it.
There is also the question of the floor underneath, and it is the one that gets ignored most. Studio floors are usually carpet over concrete, or rubber, or occasionally sprung timber. Carpet over a concrete slab is a genuinely warm combination for a floor to be in a cold season, and it is also a combination that holds heat in a way that makes a class warmer than the thermostat suggests. A studio that is genuinely warm in February is usually warm because of the floor, not the heating, and the floor is exactly what you cannot control by taking a layer off.
Why the fabric against the mat is a separate question from the fabric against you
Once you have accepted that you cannot disinfect the mat, the useful question becomes: what is between you and it, everywhere? The answer is your clothing, and it behaves differently depending on the fabric and the construction. A smooth, tightly woven synthetic surface that is slightly tacky will grip the mat lightly and stay put. A textured or ribbed surface will interlock with the mat's texture and stay put better, and it will also pick up whatever is on the mat and hold it. A brushed fleece surface will behave completely differently again, because the pile compresses and then springs back, and that compression is what lets it absorb moisture and dry slowly.
This is why the leggings in this guide lean toward smooth, dense, high-waist knits rather than brushed or waffle ones. Waffle knits and brushed interiors are excellent for warmth and for a studio that is cold in January. They are the wrong choice for a mat you did not wipe yourself, because the pile is a sponge, and a sponge picks up and holds whatever it touches. If you are going to lie on a mat you did not clean, a smooth surface that you can also wash at home in a normal cycle is a better bet than a textured one, even if the textured one is warmer.
The same logic runs through the socks, and socks are where most people are less careful than they think. A smooth knit sock with a fine grippy panel on the sole will spread your weight over the whole ball of the foot and the toes, and it will keep your foot from sliding on a mat that has just been cleaned and is still slightly damp. A thick terry or heavily ribbed sock concentrates pressure onto a smaller area, which is exactly the surface that is most likely to have been on someone else's feet before you, and it is also the surface that stays damp longest because it has more fibre to hold water.
There is one more layer of this that people rarely think about, and it is the waistband and the hem. A high-waisted legging puts a wide band of fabric between your lower back and the mat for the entire supine portion of a class. A cropped or low-rise bottom puts a narrow band, or worse, bare skin, against the surface. When the mat is not yours, the amount of fabric that is between your body and somebody else's residue is a variable you can control, and the high-waisted, full-length options here maximise it without adding any bulk that would make the position uncomfortable.
Where this leaves you
There is a routine that solves most of this and takes about ninety seconds. Wipe the full length of the mat with the towel, not just the centre, running the towel down the length of the mat rather than across the middle. That covers the hand positions, the knee positions and the shoulder positions as well as the torso. Then unfold the towel and lay it flat, rather than folding it into a rectangle and putting that on the mat, because the flat version does not become a ridge under your sacrum. If the studio has a spray bottle of its cleaning solution, use it on the towel rather than on the mat, because the mat is the surface you are trying to protect and the towel is the thing you are going to wash at home.
Then there is the order of dressing, which is a small thing that turns out to matter. If you get into your leggings and your socks after you have wiped the mat, and not before, the sweat you generate while putting them on is generated in the clothes rather than on the mat. If you dress first and then wipe, you are putting clean, dry hands on a wet towel and then lying on it. It is a two-second difference in the sequence and it is free.
The honest summary is that a shared mat is a fixed condition of a busy studio, and the clothing cannot make it clean. What the clothing does is control the number of layers between you and it, and how much of each layer is a smooth surface that washes easily. You cannot choose the mat. You can choose to have more fabric between you and it, and you can choose that fabric to be something you would be willing to wash at home at sixty degrees without a special cycle.
A two-minute routine for a mat you did not wipe
- Wipe the full length of the mat with the towel, not just the middle third
- Lay the towel flat rather than folding it, so it does not become a ridge under the sacrum
- Spray the studio's cleaner onto the towel rather than directly onto the mat
- Put your socks on after you have wiped, so the sweat you generate while dressing does not go onto the surface
- Choose smooth, densely knitted bottoms over waffle or brushed fleece for a mat you did not clean
- Look for a wide, high waistband so more fabric sits between your lower back and the mat
The Short Version
You cannot choose the mat. You can choose how much of yourself is touching it, and what that fabric is made of.
Questions people actually ask
Should I bring my own towel to Pilates?
Bring one, and the reason is not the towel as a barrier, it is that a towel is a thing you can take away and wash at sixty degrees. A studio towel used on forty people before you is a shared surface with a cleaning schedule you have no visibility into, and it is a much better idea to use your own. The mistake is stopping there. A folded towel on a grippy mat bunches under the knees and rolls into a ridge under the sacrum, so lay it flat and wipe the whole mat rather than just where you plan to lie.
Is it a problem to wear leggings rather than shorts on a shared mat?
It is a problem in the opposite direction from what people usually assume. A full-length legging puts a continuous layer of fabric between your skin and the mat, and a wide high waistband puts more fabric over your lower back specifically, which is the part of the mat that gets the most contact for the longest. Shorts or a cropped bottom put bare skin and a narrow band against a surface you did not wipe. If anything, on a shared mat, more coverage is the safer choice, provided the fabric is smooth and washes easily.
What about the studio's own cleaning spray?
Use it on your towel rather than on the mat. The mat is a soft, textured, closed-cell surface designed to grip, and it holds whatever is applied to it rather than shedding it, so repeated spraying can leave a film that becomes more irritating over a week of classes. Your towel is a piece of fabric you take home and wash. The order of operations also matters: wipe first, then spray the towel, then dress. That way you are not putting damp hands back onto the surface you just cleaned.
