What Are Buoyancy Shorts?
Buoyancy shorts are a special type of swimwear designed to help swimmers stay afloat. Made mostly from neoprene material, these shorts help lift your hips and legs in the water. The result? A better swimming position, improved technique, and a smoother swim overall.
Many swimmers—whether beginners, triathletes, or even professionals—struggle with body alignment in the water. If the hips and legs sink, the swimmer creates more resistance and moves slower. Buoyancy shorts are designed to solve that problem. They give just the right amount of lift to keep the body flat and balanced.
In this article, we’ll explore everything you need to know about buoyancy shorts. You’ll learn how they work, who they’re for, how to use them, and how they compare to other training tools. Let’s dive in.
How Buoyancy Shorts Actually Work
Buoyancy shorts are designed to give your lower body extra floatation. When you wear them, your hips and legs stay higher in the water. This helps you swim in a flatter, more horizontal position—just like professionals do.
The shorts are made from a material called neoprene. This is the same stuff used in wetsuits. Neoprene has a natural ability to float, which is why it works so well in water. Most buoyancy shorts are 3mm to 5mm thick, which provides just enough lift without feeling bulky.
When your body is flat in the water, you face less resistance. Less resistance means you swim faster and with less effort. It also allows you to focus on other parts of your stroke, like breathing and arm movement.
For many swimmers, especially beginners, maintaining proper form is difficult. Their legs tend to sink, and that ruins the balance. Buoyancy shorts make it easier to hold the correct body position, so you can train your muscles to remember how it feels to swim properly.
Who Should Use Buoyancy Shorts
Buoyancy shorts are not just for elite swimmers. In fact, they are most helpful for beginner and intermediate swimmers who are working on their technique. They are also widely used by triathletes, who want to simulate the feeling of swimming in a wetsuit during training.
If you are learning to swim, buoyancy shorts can help build your confidence. You won’t have to worry about your legs sinking or struggling to stay up. This makes it easier to concentrate on your breathing, kicks, and strokes.
Triathletes love buoyancy shorts because many races allow wetsuits. But you can't always wear a wetsuit in the pool for practice—it gets too hot and uncomfortable. Buoyancy shorts are the perfect solution. They feel similar to a wetsuit in terms of support but are comfortable enough to wear during indoor swim sessions.
Even professional swimmers can benefit. When tired or during recovery sessions, buoyancy shorts help maintain proper form without putting too much strain on the body.
If you have weak core strength, poor flexibility, or are recovering from injury, buoyancy shorts can make swimming more accessible and enjoyable.
How to Choose the Right Pair
Choosing the right buoyancy shorts is important. Not all shorts are made the same, and the wrong pair could affect your swimming comfort or performance.
First, check the thickness. Most buoyancy shorts come in 3mm or 5mm thickness. Beginners usually benefit from thicker shorts because they offer more lift. Experienced swimmers often prefer thinner options for a more natural feel.
Second, consider the size. A snug fit is best. If the shorts are too loose, water will flow inside and reduce their effectiveness. If they are too tight, they may restrict movement or cause discomfort. Most brands provide sizing charts to help you find the perfect fit.
Third, look at the material quality. Go for high-quality neoprene that is smooth, stretchy, and durable. Good stitching and a strong waistband are also important so the shorts stay in place.
Popular brands like Zone3, ROKA, HUUB, and Blueseventy offer well-reviewed buoyancy shorts. It’s worth investing in a good pair that will last for years.
Finally, think about your swim goals. Are you using them for technique improvement, triathlon training, or rehabilitation? Choose a pair that matches your purpose.
Benefits Over Traditional Swim Aids
Swimmers often use tools like kickboards, pull buoys, or fins. While these have their place, buoyancy shorts offer unique advantages.
Take pull buoys, for example. They go between your legs and keep them floating, which is good for practicing your arm strokes. But they restrict your kick. This means you're not practicing full-body movement. Buoyancy shorts, on the other hand, lift your legs while still allowing you to kick normally.
Kickboards are good for leg workouts but can cause your body to tilt and affect your alignment. Fins add speed but don’t help you float.
Buoyancy shorts give you the best of both worlds. They help you float like a pull buoy, but you can still swim freely. They’re ideal for simulating open-water swimming or wetsuit conditions.
They also promote muscle memory. Over time, your body gets used to the feeling of swimming in a good position. So when you swim without the shorts, you’ll naturally keep better form.
Using Buoyancy Shorts the Right Way
It’s important to use buoyancy shorts wisely. Don’t wear them in every session. Instead, include them in specific sets or drills during your swim training.
Start by wearing them for warm-ups. This allows your body to settle into the right position from the start. Then, use them during technique drills. Focus on your breathing, arm strokes, and body rotation. You’ll notice it’s easier to control your movements when your hips are lifted.
Some swimmers use them during long endurance sets. This helps reduce fatigue and lets you focus on consistency and speed.
However, avoid becoming too dependent on them. Mix in regular swim sets without the shorts. This will help you build real strength and balance.
Always rinse the shorts with fresh water after use and dry them in a shaded place. Don’t leave them in direct sunlight or hot cars, as this can damage the material.
Common Mistakes to Avoid
While buoyancy shorts are easy to use, there are some mistakes swimmers often make.
Wearing the wrong size is one of them. If your shorts are too tight or too loose, they won’t work as intended. Always check the size guide and try them on before use if possible.
Using them in every session is another mistake. Relying on buoyancy shorts too much can prevent you from developing your core strength and natural body position. They should support your training—not replace your technique.
Not drying them properly can ruin your investment. Neoprene is strong, but only if you take care of it. Always rinse and air-dry the shorts to avoid damage from chlorine or saltwater.
Lastly, ignoring feedback from your body and coach while using buoyancy shorts is a missed opportunity. Pay attention to how your body feels when using them. This awareness will help you apply that same body position when you swim without them.
Conclusion: Why Buoyancy Shorts Are Worth It
Buoyancy shorts are one of the best tools you can add to your swim training. They help lift your hips, improve body position, and let you swim more efficiently. They’re especially useful for beginners, triathletes, and anyone working to improve technique.
The benefits go beyond just floating. They improve your confidence, reduce drag, and make swimming more enjoyable. And unlike pull buoys or kickboards, they allow natural movement—making them more effective for real-world swimming.
If you want to swim better, feel better in the water, and train smarter, buoyancy shorts are absolutely worth trying.
