Best Workout Underwear for Women

When it comes to workout wear, most women spend plenty of time choosing the right leggings, sports bra and trainers. Underwear is often overlooked, yet it can have a bigger impact on your comfort than almost any other item you wear to the gym or for long runs.

The wrong underwear can lead to chafing, bunching, sweat build-up and constant adjustments throughout your workout. The right pair should do the opposite. Your underwear should move with your body, keep you comfortable and allow you to focus on your training rather than adjusting what you are wearing.

Whether you are lifting weights, running, walking, practising yoga or simply living an active lifestyle, choosing the right underwear matters particularly for women looking to stay comfortable.

The best workout underwear for women combines breathability, moisture management, comfort and coverage to help you feel confident during every exercise.

In recent years, there has been a shift away from traditional underwear styles. Plenty of women are now embracing boyleg pants, full briefs and crop tops that provide greater comfort and range of movement. As a result, boxer-style underwear is no longer just a men’s product; women are discovering these practical styles often outperform traditional options, both in and out of the gym.

What Makes Good Workout Underwear?

Women know that not all underwear is designed for exercise. During physical activity, your body generates heat and sweat. Underwear that traps moisture against your skin becomes uncomfortable and often leads to irritation, chafing and bacterial growth.

The best workout underwear for women typically features:

• Moisture-wicking fabrics such as nylon, Lycra or performance blends
• A breathable cotton gusset
• Stretch for unrestricted movement
• Comfortable waistbands that don’t roll or dig in
• Minimal seams or seamless underwear options
• Coverage that stays in place throughout your workout

Ideally, your underwear should be so comfortable, you barely notice it is there.

The Best Fabrics for Workout Underwear

When choosing workout underwear, style is only part of the decision. The fabric they are made from can have a significant impact on not only comfort and performance, but durability.

The right material helps regulate temperature, manage moisture and reduce irritation during exercise. The wrong material however, can leave you feeling hot, damp and uncomfortable long after you’ve finished your workout.

Synthetic Performance Fibres

A lot of activewear on the market utilises synthetic fibres such as nylon, polyester, elastane and Lycra. These materials are popular because they are lightweight and have great moisture wicking abilities.

Performance fabrics are designed to:

• Dry quickly
• Stretch with movement
• Retain their shape
• Resist wear and tear
• Support moisture management

This design is why we see a lot of workout wear incorporating synthetic fabrics. They do a great job at wicking sweat away from your body, allowing it to evaporate more quickly.

Cotton and Natural Fibres

Many women love cotton and natural fibres and it isn’t hard to see why; they are soft and breathable and they make a great choice for underwear. However, during intense exercise, there are a few limitations.

Unlike some synthetic fabrics, cotton doesn’t allow sweat and moisture to evaporate as easily. It absorbs and retains moisture, leaving it heavy and slow to dry. This then increases the potential of friction and discomfort during longer workouts.

The good news is that women don’t need to avoid cotton altogether. Many high-quality underwear options incorporate a cotton gusset to improve breathability and comfort where it matters.

Blended Fabrics

Many women find that workout underwear made from blended fabrics offer the best of both worlds. A combination of natural and synthetic fibres means that manufacturers can create underwear that delivers softness and breathability without losing the stretch and moisture management.

What are SWAG Women’s Underwear and Crop Tops Made From?

With comfort at the top of mind, SWAP women’s underwear and crop tops are made from a premium blend of bamboo-derived viscose, cotton and elastane. This combination provides an ideal balance between softness, breathability, stretch and durability.

Bamboo-Dervied Viscose

Bamboo-derived viscose is becoming increasingly popular in women's clothing and underwear because of its naturally soft feel against the skin. Many women describe bamboo fabrics as feeling smoother and softer than traditional cotton. It sits against the skin and provides  excellent breathability making it a good option no matter the time of year. 

Bamboo-derived fabrics are known for:

• Silky-soft texture
• Breathability
• Temperature regulation
• Lightweight comfort
• Everyday durability

Women will benefit from the qualities of bamboo-derived viscose underwear whether they are working out, working or relaxing at home.

Cotton

Remaining one of the most trusted natural fibres in clothing, cotton’s breathability and softness make it a critical component in comfortable underwear, helping to promote airflow where it’s needed. 

Incorporating cotton into the fabric blend means that SWAG underwear delivers the softness many women love, with durability for regular wear.

Elastane

Is activewear really activewear if it doesn’t stretch with your body? Elastane allows SWAG underwear to move naturally with your body, while retaining their shape overtime. 

The addition of elastane provides:

• Flexibility during movement
• Improved fit
• Shape retention
• Long-lasting comfort

The combination of bamboo-derived viscose, cotton and elastane creates a fabric that feels comfortable from the moment you put it on. Rather than focusing solely on performance or appearance, SWAG has been designed to support everyday life, whether that be your early morning workout, school drop-offs, or weekends spent exploring outside.

Why Your Underwear Matters During Exercise

It is easy to underestimate the role underwear plays in your overall comfort during exercise, especially if you are only just getting into exercise, or trying something which requires different movements to your usual workouts.

When underwear doesn’t fit properly, it can create a range of distractions, including:

• Chafing
• Visible lines under workout clothes
• Riding up
• Rolling waistbands
• Fabric bunching
• Excessive sweating
• Skin irritation

These issues become even more noticeable during longer workouts, or activities that require repetitive movement, such as running, cycling or walking.

The right underwear helps eliminate these distractions so you can focus on your workout rather than constantly adjusting your clothing. 

Why Moisture-Wicking Matters in Workout Underwear

Most women have finished a workout feeling damp, uncomfortable or irritated - and it isn’t enjoyable. But this is why sweat wicking matters. During exercise, your body naturally produces sweat as a way of regulating temperature. Sweat itself isn’t the problem. The issue is when sweat becomes trapped against the skin.

Moisture-wicking refers to the ability of the fabric to move sweat away from the skin and disperse it across the outer layer of the material. This means that sweat isn’t sitting directly on your skin in one or two places - the fabric helps to spread it out meaning it evaporates more efficiently leaving women more comfortable during and after exercise.

This is one of the reasons bamboo-based fabrics have become increasingly popular. Their breathable nature helps to create comfortable underwear that performs well, in and out of the gym.

Best Workout Underwear for Women Under Leggings

Leggings remain one of the most popular activewear choices, which means finding underwear that works well underneath them is essential. One of the biggest concerns women have when wearing tight leggings is how to avoid visible panty lines. Many choose styles with a seamless design to create a smooth silhouette, while others prioritise comfort and coverage over a completely invisible look.

The best workout underwear under leggings should feel lightweight, stay securely in place and move naturally with your body. One of the worst things mid-workout is to feel everything rolling down.

SWAG women’s briefs offer a comfortable, streamlined fit that sits smoothly under activewear while still providing more coverage than many traditional workout styles.

For women who prefer additional coverage and comfort, SWAG women’s boyleg pants are becoming an increasingly popular choice. The body-hugging fit helps reduce movement and bunching, while the extra coverage can provide greater confidence during squats, stretching and everyday movement.

Whether you are heading to a Pilates session, a gym session, or shopping after your workout, comfort should be your priority.

Best Workout Underwear for High-Intensity Training

High-intensity workouts place extra demand not just on your body, but your clothing as well. Running, HIIT classes, spin sessions and functional workouts involve repetitive movement and increased sweating. Underwear that shifts, rides up or causes friction quickly becomes uncomfortable.

The best underwear for high-intensity training should offer:

• Moisture management
• Breathability
• Stretch
• Secure fit
• Minimal chafing

One of the biggest complaints of many women is their underwear riding up during exercise. Traditional styles often struggle to stay in place during jumping, running or squatting movements. This is where boyleg styles can make a significant difference.

SWAG women’s boylegs are designed to provide comfortable coverage while helping reduce chafing between the thighs. The longer leg design stays in place during heavy movement, making them ideal for workouts at a higher intensity.

Many women who switch to boyleg style underwear find they spend far less time adjusting their clothing, meaning they can spend more time getting optimal results from their workout.

Best Workout Underwear for Comfort and Coverage

Women know that not every workout needs to be about pushing your limits. Some days a quieter workout is better, where comfort is the priority. It might be walking the dog, working out from home or even enjoying a recovery day, and these days are where boyleg underwear is best. They offer:

• Greater comfort throughout the day
• Less riding up
• Reduced thigh chafing
• Better coverage during movement
• A secure fit that stays in place

SWAG women’s boyleg pants have been designed specifically for women looking for underwear that feels comfortable from morning to night. The fit allows for practical coverage many active people prefer without feeling restrictive.

If you favour a more traditional cut, SWAG’s women’s briefs deliver the same comfort and wearability with a familiar design. 

The best workout underwear isn’t always the most technical or most expensive option. More often than not, it's the pair you forget you’re wearing.

Best Full Coverage Underwear for Periods and Leaks

Working out during your period presents its own set of challenges (including often the motivation to do a workout). Many women look for underwear that provides extra security, comfort and confidence during this time of the month.

The ideal workout underwear women look for during their period is:

• Comfortable
• Breathable
• Supportive
• Able to handle increase moisture

Many women pair comfortable, full-coverage underwear with their preferred period products, helping them stay active throughout their cycle.

SWAG’s women’s underwear range provides a secure, comfortable fit that moves with your body, making it a practical option for everything from gentle beach walks to gym sessions. 

What Women Look for in Workout Underwear

If you spend a few minutes speaking to women about the best underwear for a workout, you’ll generally hear the same priorities repeated over and over again.

Women want underwear that:

• Stays in place
• Doesn’t ride up
• Feels breathable
• Handles swear well
• Doesn’t cause chafing
• Remains comfortable all day

These considerations are one reason why boyleg pants have become increasingly popular among women. While traditional styles certainly have their place, many active women are finding that a little more coverage often leads to a lot more comfort.

Don’t Forget Your Crop Top

Underwear is only one part of the equation when it comes to workout wear. Any woman knows that a comfortable crop top can make a world of difference to their workout.

The best crop tops provide support without restriction, allowing women to move freely while remaining comfortable throughout their workout.

SWAG’ women’s crop tops are designed for versatility, making them suitable for:

• Gym sessions
• Walking
• Yoga
• Travel
• Everyday wear
• Layering under activewear

When paired with SWAG boyleg pants for briefs, they create a comfortable foundation layer that supports women in the gym.

Why More Women are Choosing SWAG

For many years, women’s underwear has often prioritised appearance over practicality, and for many women, it can be difficult to find underwear that fits well.

SWAG takes a different approach.

The focus is on creating underwear that women enjoy wearing, whether that be when exercising, travelling, working, relaxing at home or managing a busy day. Comfort is a priority and should never be compromised.
