Hot Yoga Clothing: What to Wear at 40 Degrees?

Imagine: you're standing in a room of 40 degrees, the humidity is so high that you feel like you're breathing underwater, and you're trying to do a graceful Warrior II. But instead of deep zen, you feel your cotton T-shirt weighing three kilos because of the sweat and slowly suffocating your freedom of movement. You look in the mirror and don't see a proud yogi, but a drowned rat whose leggings are starting to sag dangerously. Believe me, I've been there. As a dance instructor and yoga fanatic, I've already made all the clothing mistakes for you, so you don't have to. The most important lesson I've learned? At 40 degrees, your clothing isn't just an outfit, it's your survival kit. The right hot yoga clothing should feel like a second skin that wicks away sweat faster than you can say "Namasté".

Before we dive deep into the world of fabrics and fits, it's useful to know which type of class you're actually taking. There's quite a difference in how you dress for a quiet session or an intense flow. Therefore, first check this article about Discovering Yoga Styles: From Hatha to Vinyasa Flow to determine what your vibe is.

Why cotton is your biggest enemy at 40 degrees

Listen, I love cotton for a lazy Sunday on the couch, but in a hot yoga studio, it's a cardinal sin. Why? Cotton is a hydrophilic fiber. That's a fancy word for: it sucks up water (and sweat) and holds onto it. In a room of 40 degrees, your body produces liters of sweat to cool down. If that sweat stays stuck in your shirt, it becomes heavy, cold (as soon as there's a breeze), and it starts to chafe. Nothing ruins your focus like a wet rag of fabric sticking to your stomach during an inverted pose.

What you *do* want are technical fabrics. Think of polyamide, polyester blends, and elastane. These fabrics are 'moisture-wicking'. They pull the moisture away from your skin to the outside of the fabric, where it can evaporate lightning fast. This helps your body regulate its temperature. When I teach in a warm room, I often wear brands that understand how a body moves. In the dance world, we swear by brands like Rummos or Werner Kern for shoes because of the technology, and for clothing, the exact same applies: technology is everything. For yoga, Hey Honey Yoga really is the gold standard. Their fabrics are developed so that they not only breathe but also provide that much-needed compression without making you feel like you're in a corset.

Actionable tip: Do the 'squeeze test'. Grab your sports shirt and squeeze it. Does it feel thick and soft like a towel? Leave it at home. Does it feel smooth, cool, and thin? That's your winner for the hot studio.

The search for the perfect hot yoga legging (squat-proof!)

There is a special place in hell reserved for leggings that become see-through as soon as you go into a Downward Dog. We've all seen it (or experienced it): the person in front of you in class unintentionally gives away a whole show because their leggings don't pass the 'squat test'. With hot yoga, there's an extra challenge: sweat spots. In light grey leggings, after ten minutes, it looks like you've had an accident.

For a good Yoga Legging, you need to pay attention to three things:

  1. The Waistband: Choose a high-waist model. Why? Because in yoga, you're constantly bending, stretching, and twisting. A low waistband slips down, meaning you're constantly hiking up your pants. A wide, high waistband stays where it belongs and also gives a nice, supported feeling to your core.
  2. Fabric Thickness: You want a fabric that is thin enough not to overheat, but has a high density so it isn't see-through. Hey Honey collections often use double-knit techniques that offer exactly this balance.
  3. Seams: Flat-lock seams are a must. These are flat seams that don't chafe against your skin when you start to sweat. Believe me, 'chafing' is no joke when your skin has become soft from the heat.

I often see girls choosing shorts for hot yoga. That can be wonderful, but watch out: if you sweat a lot, your legs become slippery. In poses like 'Tree Pose' (Bakasana), you need grip from your foot against your leg. With long leggings, you have that grip; with bare, sweaty legs, you slide right off. If you do go for shorts, choose a model that is tight around your thighs so you don't give an unwanted view during inverted poses.

Hot yoga tops and sports bras: Support without suffocation

Upper body clothing in hot yoga is a minimalist game. Many advanced yogis wear only a sports bra, and honestly, I don't blame them. The less fabric you have on, the easier your body cools down. But I also understand that not everyone feels comfortable with that.

If you choose Yoga Tops, go for a 'fitted' model. A loose-fitting shirt might seem nice and airy, but as soon as you bend forward, that shirt hangs in your face and you can't see anything anymore. Moreover, a loose shirt absorbs less sweat directly from your skin, causing it to run down your back. Yuck.

A good sports bra for hot yoga doesn't have to be 'high impact' like for running (unless you have a very large cup size and really need that extra support), but it must breathe. Avoid bras with thick padding or push-up cushions. Those things act like sponges. They soak up sweat and become heavy as lead. Choose a model with thin, removable cups or just a single layer of sturdy, technical fabric. The Yoga Clothing Sets we recommend at Miss Salsa often have matching tops that offer exactly the right balance between style and functionality.

My personal tip: Pay attention to the back of the top. Racerback models or tops with many straps (strappy backs) not only look great, but they leave your shoulder blades free. This is essential for your freedom of movement in flows where you move your arms above your head a lot.

Bikram Yoga: Less really is more

Bikram yoga is the 'hardcore' version of hot yoga. 90 minutes long, 26 poses, and a steady 40 degrees with 40% humidity. This is not the moment for your trendy, thick lifestyle leggings. In Bikram, you often see people wearing as little as possible. For ladies, this often means very short shorts (hot pants) and a sports bra.

Why so extreme? Because in Bikram, you use your own reflection to check your alignment. You want to be able to see your knees to check if they are 'locked'. You want to be able to see your abdominal muscles to see if they are engaged. In wide pants, you simply don't see that.

If you go for a Bikram yoga set, make sure the fabric is extra thin. Brands like Hey Honey have specific lines that feel almost like silk, but with the strength of sportswear. And don't forget your towel! In a Bikram class, your towel (which you lay over your mat) is just as important as your clothing. Without a towel, you turn your mat into a water slide, and that is life-threatening for your joints.

The cooling-down phase: What do you wear after that sweat session?

This is where most people go wrong. You come out of that warm room, your endorphins are racing through your body, and you step right out into the cold outside air (especially in the Netherlands!). Your muscles are warm and flexible, but due to the sudden cold, they can cramp up lightning fast. Moreover, your clothing is wet, and wet clothing draws heat away from your body.

Make sure you always have a 'layer' with you for after class. One of our Yoga Sweaters is perfect to slip on right over your top. Choose an oversized model made of natural material such as organic cotton or bamboo for after class. This absorbs the last bit of sweat while you cool down and keeps your muscles warm while you cycle home or get into the car.

I always tell my dance students: "The cooling down only starts once you have your coat on." That applies to yoga too. Protect those hardworking muscles. A stiff neck after a wonderful yoga session because you stood in a draft is the last thing you want.

How to keep your expensive yoga clothing fresh (and stretchy)?

You've finally invested in a beautiful set from Hey Honey, and after three classes it's starting to smell a bit... well, musty. Hot yoga sweat is different from regular sweat. It's full of bacteria and salts that settle deep into the fibers of your clothing.

My golden rules for maintenance: 1. Rinse immediately: If you can't wash right away, rinse your clothes immediately after class with cold water. Don't leave it in a closed gym bag for two days. That's a breeding ground for odors you'll never get out. 2. No fabric softener: This is the most important one! Fabric softener leaves a layer over the fibers of your technical clothing. This causes the fabric to lose its breathability and its power to wick away sweat. Use a mild liquid detergent. 3. Air dry: The dryer is the enemy of elastane. The heat breaks down the elastic fibers, causing your leggings to lose their 'stretch and recovery'. Hang your clothes up. Thanks to the technical fabrics, it's often dry within a few hours. 4. Vinegar trick: Does your clothing still smell? Add a splash of natural vinegar to the fabric softener compartment. Vinegar kills the bacteria and neutralizes odors without affecting the fabric.

Frequently asked questions about hot yoga outfits

1. What do you wear for hot yoga?
Preferably wear tight, moisture-wicking leggings (or shorts) and a breathable sports bra or tight-fitting top. Avoid cotton and choose synthetic fabrics specifically designed for sweating and movement.

2. Can I wear the same clothing for hot yoga as for regular yoga?
In theory, yes, but in practice, regular yoga clothing is often too thick or made of cotton. For hot yoga, you really need clothing that dries faster and is lighter. Thick, cotton leggings that are wonderful for Yin Yoga become a heavy burden during hot yoga.

3. What clothing is suitable for Bikram yoga for women?
For Bikram yoga, we recommend as little fabric as possible. Short yoga shorts and a sports bra are ideal. This gives you maximum freedom of movement and ensures you can see your alignment clearly in the mirror.

4. Can I lose weight with hot yoga?
Hot yoga is an intensive workout where your heart rate goes up and you burn many calories. Although most of the weight loss immediately after class consists of fluids, the physical effort certainly contributes to fat burning and muscle building in the long term.

5. Do I need to wear shoes during hot yoga?
No, you do yoga barefoot for maximum grip and balance. If you suffer from sweaty feet and are afraid of slipping, you can consider special yoga socks with grip studs, but most people prefer a good yoga towel over their mat.

6. Aren't leggings too warm?
It seems that way, but a good technical legging actually helps with the evaporation of sweat, which can have a cooling effect. Moreover, it protects your skin from chafing and provides grip in certain poses.

So, now you're completely ready to step into that studio without clothing stress. Remember: the best outfit is the one you forget as soon as the class begins. If you're not busy pulling up, adjusting, or wiping, you can truly concentrate on your practice. Still have doubts about the size or model? Feel free to send us a message at Miss Salsa.
