Best Sauna Suit: Tested and Reviewed

The best sauna suit isn’t necessarily the one with the highest price tag. It’s about finding the right fit for your workout style, whether boxing, cardio, or strength training. Comfort, durability, and heat retention matter most when you’re looking to make sauna suits a regular part of your fitness routine.

There is no one-size-fits-all perfect sauna suit, but here are four of the best options to get you started.

Here’s the List:

How Each Sauna Suit Was Tested

• Durability: How well does each suit hold up during intense workouts? Can it handle pulls, stretches, and repeated use?
• Heat Retention: Does it trap heat effectively or let it escape through poor seams and materials?
• Comfort: Is it comfortable during exercise, or does it feel restrictive?
• Design and Features: Does it have pockets, ventilation, and reflectors?
• Care and Maintenance: Can it be machine-washed and dried, or does it require special care?
• Quick Removal: Is it easy to quickly take off when you’re getting too hot during workouts?

Best Overall: BVVU

The BVVU sauna suit is best overall because of its thoughtful design and unbeatable value. It’s the only suit I’ve tested with a removable hood. I love having the hood for running but hate it when lifting weights. Being able to remove it makes a huge difference.

The material is surprisingly flexible and durable. I’ve put this suit through intense gym sessions, runs, and walks without a single tear. Most sauna suits rip easily, but this one holds up well. The breathable mesh in the crotch area adds elasticity to the pants and helps prevent overheating.

One standout feature is the smooth material covering the inner seams. This might sound minor, but it makes a noticeable difference in comfort compared to other suits, where rough seams can irritate your skin during workouts. The jacket has a large front pocket accessible through two zipper openings surrounded by reflective tape, which makes the night workouts safer.

The fit runs true to size, but I recommend ordering one size up if you’re doing exercises like pull-ups, squats, or chest flies. The extra room gives you more freedom to move without feeling restricted. The elastic cuffs at the wrists and ankles do a great job trapping heat.

I recommend wearing regular workout clothes underneath. The sweat has nowhere to go without them, so it pours out of the sleeves, waist, and ankles and feels pretty gross. With underclothes, this sauna suit is comfortable enough for long workouts.

At around $85, it offers incredible value for money. It’s cheaper than most alternatives while delivering better performance and durability. For anyone serious about sauna suit training, this is the clear winner.

Best Boxing: Boxraw Hagler 2.0

The Boxraw Hagler 2.0 is the gold standard for combat sports training. This suit is specifically designed for boxers and shows in every detail. The elastic wrist straps have adjustable velcro cuffs that work perfectly with boxing gloves — something other suits ignore entirely.

Professional fighters like Gervonta Davis, Floyd Mayweather, and Canelo Alvarez use this suit, which speaks to its quality and performance. The light but durable fabric moves with you during intense training sessions. I’ve tested it without tears or restrictions during heavy bag work, shadow boxing, and cardio sessions.

The rubberized inside lining feels great against the skin. The elastic waist has drawstrings for proper adjustment and features the signature Boxraw logo, which looks great. The jacket has a kangaroo pouch perfect for storing your phone or keys, and the side pockets on the pants have reflective strips for safety during low-light, low-visibility workouts.

One major downside is the lack of ventilation. Since it’s a pullover design, you must completely remove the jacket or roll the sleeves to cool down. This can make it too hot too quickly.

Sizing can be tricky since popular sizes sell out fast. Some customers report receiving orders late or getting the wrong product altogether. The newest versions are only available on Boxraw’s website, with limited options on Amazon.

It’s expensive at $120, but the durability, flexibility, and attention to detail justify the price for serious fighters. This is worth the investment if you’re into boxing or MMA and want the same gear the pros use.

Best Waterproof: Hotsuit

The Hotsuit stands out for its waterproof capabilities and unique heat-indicating logo. The thermo-reactive logo changes color to show how heated up you are.

The suit’s completely waterproof and windproof design makes it perfect for outdoor workouts. Although your regular workout clothes underneath will be completely soaked after exercising, the suit itself handles moisture well.

The jacket has a long zipper for easy on/off and a quarter-zip for ventilation. This reduces the heat intensity without removing the entire jacket. The pants’ wide-leg cut provides good mobility and comfort during exercise.

However, the sizing is a major issue. This suit runs extremely small — I usually wear medium or large, but I needed a 2XL for a proper fit. The material also isn’t flexible, so correct sizing is crucial to prevent tearing during workouts. The adjustable ankles and hood trap heat, but the hood design is awful.

When tightened, the hood covers your eyes and swallows your head. You’d need to wear a hat underneath to make it work. I wish the hood were removable like the BVVU suit.

Some customers say the suit has a strong chemical smell when new, although mine did not. The off-center zipper looks cool but adds no functionality. For $99 on Amazon ($139 on Hotsuit’s website), better options are available unless you need waterproof capabilities.

Best Budget: MRX Heavy Duty Sweat Suit

The MRX Heavy Duty Sweat Suit is perfect for anyone wanting to try heat therapy without a big investment. At $35, it’s incredibly affordable while still offering decent quality and durability. The double-stitched construction and quality EVA nylon and neoprene materials make it more durable than you’d expect at this price.

The design is simple and clean—black with colored stripes down the arms and legs and a small MRX logo. The elastic neck, wrists, waist, and ankles effectively trap heat, which is the main purpose of any sauna suit.

However, the lack of flexibility is a big limitation. It’s fine for walking and light exercise, but anything requiring lots of movement will probably cause tearing. When you raise your arms overhead, it feels tight.

The size range is limited to waist sizes between 32 and 44 inches, which won’t fit smaller or larger people. There’s also no built-in ventilation, pockets, or zippers. It’s as basic as sauna suits get. The hood does have drawstrings, though.

Some customers report loose stitching and premature wear. For the price, you’re getting a functional sauna suit that will make you sweat, but don’t expect much more.

This is a great starting point if you’re curious about sauna suits but don’t want to spend much. Just know that you’ll probably want to upgrade to something more flexible and durable later.

Things to Consider Before Buying

Fitting

Most sauna suits run small or have limited size ranges. Check the manufacturer’s sizing chart carefully and consider ordering a size up for better movement.

Adjustability

Adjustable wrist straps and drawstrings on hoods and waists make a big difference.

Flexibility

Stiffer materials restrict movement. If you do anything more than walking or light cardio, prioritize flexible materials.

Durability

Reinforced seams are worth paying extra for.

Ventilation

Look for suits with zippers or other ventilation options. It’s ideal to cool down without complete removal.

What to wear underneath

Wear regular workout clothes underneath to soak up sweat. Going without makes it uncomfortable and messy.

Important Features

Consider what you actually need. Pockets, reflective strips, and removable hood options are available.

care and maintenance

If your sauna suit is not machine washable, ensure you’re okay with hand-washing it after each use. Personally, I hate hand washing and avoid using sauna suits that require it.

Conclusion

Choosing the right sauna suit depends on your specific needs and budget. Each option above offers unique advantages, but my favorite is the BVVU for its versatility, durability, and value.

Ultimately, it’s about finding the right balance between features and price, whether cutting weight for a fight or just exploring the benefits of heat therapy on a budget, there’s a solid choice here to get you started.

One crucial reminder: hydration is everything. Dehydration is the most common—and most dangerous—risk when using sauna suits. Serious health incidents, including deaths, have been linked to intense training and rapid weight loss with sauna suits. Always hydrate well before, during, and after each session. If you feel dizzy, weak, or mentally foggy, immediately remove the suit and drink fluids containing electrolytes. When in doubt, seek medical attention.
