The best sauna suits of 2024

Wearing a sauna suit can be very unpleasant, but that’s the point. These waterproof tracksuits trap heat, resulting in a higher production of sweat. Studies have shown that sweating has some benefits, though that is far from conclusive at this point. Beyond the potential health benefits, these suits are frequently worn by athletes competing in weight-class sports—such as wrestling or MMA—in order to cut weight. While more studies need to be done on the effects of wearing sauna suits, keep in mind that staying hydrated and taking breaks are important when wearing one. Be sure to replenish with lots of water, and don’t over-exert yourself. Also, consult a doctor before using one because even the best sauna suits can do serious harm when used improperly.

How we chose the best sauna suits

The writers and editors at PopSci have years of experience covering fitness products—from CrossFit shoes to vegan protein powders and beyond. To find the best sauna suits, we started with a list of dozens of options before narrowing them down based on variables like fit, durability, and design. We relied on a mixture of first-hand experience, professional reviews, user feedback, and spec comparisons to determine the models that offer the best performance and value.

The best sauna suits: Reviews & Recommendations

Studies show that sauna suits do indeed help you sweat more without having to increase the intensity of your workouts, up your sauna times, or increase sauna heat. While the primary function of sweating is to cool the body down when it’s overheating, people also sweat to enjoy some general health benefits. Multiple studies show varying benefits of induced sweating, such as helping to prevent dementia and Alzheimer’s, reducing oxidative stress, and aiding in respiratory illnesses. However, the science is far from settled.

Athletes who participate in sports with weight classes also often employ sauna suits to help cut weight, though that process can cause serious health issues and should only happen under careful medical oversight. Keep in mind that if you’re new to wearing a sauna suit and are sweating much more than usual, you may feel dizzy or lightheaded. You’ll need to be extra careful about your hydration. It’s absolutely essential that you don’t try to use these for general weight loss. They can be very dangerous, and any weight loss effects will be temporary.

Specs

• Material: Neoprene, rubber
• Sizing: Small – 5XL
• Care: Hand wash only in cold water, hang to dry

Pros

• Windproof/waterproof
• Patented Silver-Heat REG V2.0 fabric
• Odor resistant 
• Large range of sizing options

This lightweight and comfy sauna suit is the newest model for the HOTSUIT line. With patented wear- and odor-resistant Silver-Heat REG V2.0 fabric, you can sweat your butt off without stinking up the joint. 

It comes in various sizes, so both men and women can enjoy this sauna suit. It can be worn in your sauna, but it’s also windproof and waterproof so that you can wear it outside in all seasons. This suit features a close cuff design to trap in heat, a waterproof zipper, drawstring detailing, and a light feel that doesn’t weigh you down.

Reviewers love how quickly they begin sweating in this suit and the material’s durability. They also noted that the design felt fresh and cooler than other models. However, you should go up one to two sizes depending on how you prefer your fit. The brand recommends pairing it with a sweat-absorbent t-shirt underneath for the most comfortable wear because it’s unpleasant against bare skin.

Best for men:  BOXRAW Hagler Professional Sauna Suit

SEE IT

Why it made the cut: Designed with world champion boxers, this 100% nylon, anti-rip sauna suit is durable, high quality, and very effective to help you sweat your butt off.

Specs

• Material: 100% Nylon
• Sizing: Small to 3XL
• Care: Machine wash cold, wash separately

Pros

• Over 1,000 positive reviews
• 100% Nylon, anti-rip fabric
• Elastic cuffs for added heat-trapping
• Lots of color and sizing options

Cons

• Size up for the best fit

The BOXRAW Hagler Sauna Suit was designed in collaboration with multiple world-champion boxers. With features like an elastic neckline and waistline to trap in heat, four pockets to store your valuables, rubberized cuffs, convenient headphone holes, and anti-rip, waterproof 100 percent nylon fabric that’s machine washable, this sauna suit set has it all for under $100. 

The thicker material avoids the “garbage bag” feeling that affects other, cheaper suits. Reviewers also point out that the company’s attention to details like heavy velcro, chest logo embroidery, and thick stitching indicated this product was more durable than other options.

It comes in several colors, and sizes range from small to 3XL. Again, this model may run small, so you likely want to order a size or even two larger than you normally would if you want a comfortable fit.

Best for women: KEBILI Sauna Suit

SEE IT

Why it made the cut: Windproof, waterproof, and made with silver PU coating, this elastic 4-way stretch fabric keeps wearers feeling comfortable and odor-free and protects your skin from irritation. 

Specs

• Material: 82% Polyester, 18% Polyurethane
• Sizing: Small to 3XL
• Care: Machine wash cold, hang dry

Pros

• 4-way stretch
• Fair pricing 
• No “plastic” rubbing noise when exercising 
• Elastic hoodie
• Very soft and comfortable

Cons

• The Korean label is difficult for some to understand
• Cannot purchase bottoms separately

Made with four-way stretch and double overlock stitching for added durability, this sauna suit for women comes with a hoodie to trap in even more heat. It’s windproof and waterproof for use in any season or weather, making it easier if you run back and forth between an outdoor sauna and a workout area.

Wearers love that there’s no plastic rubbing sound when working out, like many other models. They also noted it has a super soft hand feel and comfortable fit.

You have the option to select the top separately, as well as purchase the complete set to customize this for your preferences and needs. The downside here is that you don’t have the option of purchasing the bottoms separately, so if you are a different size on top and bottom, you’re in a bind. Customers recommend sizing up if you’re in between sizes.

Best budget: RAD Sauna Suit

SEE IT

Why it made the cut: This high-quality unisex nylon sauna suit comes in sizes medium to 6XL and costs under $40, so you can get your sweat on without hurting your wallet. 

Specs

• Material: Nylon
• Sizing: Medium-6XL
• Care: Machine wash cold and line dry

Pros

• Super budget-friendly
• Inclusive sizing up to 6XL
• Night vision reflective logo
• Adjustable velcro cuffs

• Sizing is off; order a size or two up

The RAD Sauna Suit is made with high-quality EVA nylon material, which matches its more expensive counterparts. With an added hood for increased heat-trapping and a cool style, the sauna suit features elastic at the cuffs, waist, waistline, and ankles for a seriously sweaty session. 

It’s designed as a unisex suit with super-inclusive sizing from medium to 6XL. It’s windproof and waterproof. It promises you’ll start sweating within five minutes of use, though you may want to pair it with an infrared sauna if you are set on achieving that.

Reviewers are amazed at the quality for the inexpensive price point, noting that it’s durable, long-lasting, and “does the job.” Note that it can feel snug in the pants, so consider that when choosing your size. Plus, some noticed light ripping or snagging after a few months. We really recommend following the care instructions to ensure your suit will last. And do not tumble dry! 

Best durability: Kutting Weight – Neoprene Sauna Suit

SEE IT

Why it made the cut: Made from the most durable Neoprene fabric, this long-lasting sauna suit is sure to offer maximum sweat sessions with minimum worries—no tears, rips, or snags.

Specs

• Material: Neoprene
• Sizing: XS-6XL
• Care: Machine wash and line dry

Pros

• Made from the highest quality Neoprene
• Sleek and slim design
• Soft hand-feel
• Excellent value
• Stylish

Cons

• Some may not like how snug it fits
• Not full body

Crafted from SweatTech elastic Neoprene, this sauna suit is built to last. The Neoprene is an updated version of the classic fabric, with a more flexible design and softer hand-feel. It’s finished with a smooth layer of lycra for even more comfort.

It features triple-reinforced stitching for added durability and mesh paneling along the sides for optimal comfort and breathability. Unlike other baggy models, the design is form-fitting and sleek to offer support through your workouts.

One big advantage comes from the look and style of this suit compared to other options. Plus, it’s even cheaper than less durable alternatives. In short, it’s an excellent value for what high quality you get. However, take note that this is not a full-body design—it stops at the forearm and knees.

Things to consider when looking to buy the best sauna suits

Material

The three main types of materials used to make sauna suits are PVC, nylon, and Neoprene. We recommend Neoprene or high-quality nylon. PVC is flimsy and cheap, making it susceptible to tears and rips.

Ventilation

Of course, you want to trap heat when wearing a sauna suit, but you also want to choose an option that breathes just enough to allow your body to cool itself. You don’t want to risk overheating or falling ill. You can literally die if used incorrectly.

Size

If your sauna suit is too tight, it might cut off circulation. If it’s too big, it might not work as effectively. Find a comfortable, true-to-size fit.

Cost

Sauna suit pricing varies depending on material and brand, but you should definitely be able to get quality suits under $100.

What else to know before buying the best sauna suits

• More research is needed. The benefits of wearing a sauna suit are largely based on anecdotal evidence. While many people have experienced great benefits from using sauna suits, it’s important to note that more clinical trials must be done to make definitive claims. Always consult with your doctor.
• They are not recommended for weight loss. Rapid weight loss due to sauna suits is only temporary (you’re losing excessive water weight that will be replenished when you rehydrate). Those with a higher BMI are at an even higher risk of dehydration, according to research.
