If you are an athlete, challenging your limits every single day through a hard grappling session, a long surf, or a high-intensity workout, you already understand the importance of ventilation. A rashguard that traps heat and moisture not only feels uncomfortable; it can also distract you and affect your focus during performance. For this reason, one of the trending rashguard styles is a breathable mesh rashguard that is used as athletic gear that provides good ventilation and comfort during training.
Athletes and workout enthusiasts need more from their gear, and the apparel industry has answered. One of the fastest-growing segments in active wear is breathable performance wear. It is because you perform better and recover faster when your body stays cool and dry.
The specialty of breathable rashguards is the mesh panel technology, which is built specifically for good airflow, wicks sweat away, and keeps you comfortable no matter how hard you push. In this guide, we will discuss the importance of breathable mesh rashguards and the common materials used to make them, so you can get the benefits you need.
What are Mesh and Breathable Rashguards?
A breathable mesh rashguard is athletic gear designed to provide various performance benefits, with ventilation as its main feature, not an afterthought. While standard rashguards are made from a blend of polyester or nylon with spandex, a breathable rashguard also includes mesh panels or open-weave fabric in strategic areas to allow airflow, which helps keep you cool during training.
Now you may wonder what mesh panels are, so let’s briefly discuss that the mesh panels are the sections of fabric that have an open grid structure. The gaps between the fibers act as a pathway to let air pass through. This strategic design significantly improves airflow compared to a standard rashguard. Some of them are designed with full mesh construction, while others use mesh panels in the places where you need it the most or on selectively high-heat zones like the underarm, upper back, and sides.
The main difference between a standard and a ventilated rashguard becomes clear when you start sweating during physical activity. Mesh panels in ventilation rashguards let that moisture escape, and that changes everything about how you feel during activity for extended periods.
Common Materials in Breathable Rashguards
The fabric blend in men's and women’s rashguards determines how they perform or provide benefits during training. The most effective breathable rashguards combine several materials to offer the unique benefits of each. Here are some of the common mesh materials:
-
Polyester: Polyester is actually the common material of most performance rashguards. It is lightweight, durable, and naturally moisture-wicking. Polyester pulls sweat away from the skin and pushes it toward the surface of the fabric, where it can evaporate.
-
Spandex (Lycra): This fabric provides the stretch and compression that make a rashguard functional. Spandex is used at 10 to 20%, which gives the fabric elasticity.
-
Nylon Blends: Nylon blends add softness and abrasion resistance, which makes them suitable for water sports and mat exercises.
-
Performance Mesh Fabric: Crafted with an open-knit structure, mesh fabric is used for its lightweight and maximum airflow. It is one of the essential fabrics in breathable rashguards.
Why Breathability Matters in Rashguards?
Here are some of the things that most athletes do not realize. Overheating during performance or training does not just make you uncomfortable, but it also affects your performance and makes you slow and less coordinated. It means it affects your ability to learn new skills and to focus completely on your form to improve yourself.
When your body temperature increases, it redirects blood from your muscles to your skin to try to cool it down. You become exhausted, and your technique gets sloppy during training. Breathable rashguards prevent heat buildup and ultimately help you improve your focus during training without getting distracted.
Benefits of Wearing Breathable Mesh Rashguard
A breathable rashguard benefits you in so many ways during training. Here are some of them as follows:
Prevents Overheating
Mesh panels integrated in rashguards allow continuous airflow across the skin surface. Rather than trapping body heat under a sealed layer of fabric, mesh zones let the air pass through them and let warm air escape to cool down the body.
Support Long Training Sessions
When you engage in long training sessions, you need something that supports you. So, a rashguard that starts feeling hot at the 20-minute workout session will cause discomfort during long training sessions. Breathable mesh panels let you continue your session with comfort and improved focus.
Helps Regulate Body Temperature
Mesh rashguards help regulate body temperature through passive cooling. The evaporation of sweat from mesh-panel areas produces a mild cooling sensation. The fabric is designed not to block the evaporation process.
Minimizes Skin Irritation and Chafing
When you wear a sweaty shirt, it can cause skin irritation from prolonged contact. But mesh rashguards control and manage this humidity, which helps minimize chafing and skin irritation. Kids' rashguards are specifically designed to provide greater comfort, using mesh panels to let kids engage in physical activities for longer.
How Mesh Panels Improve Ventilation
The rashguard is smartly designed to meet the real-world performance demands. A well-crafted breathable rashguard is not manufactured with mesh everywhere, but only presents where the body generates the most heat.
-
Underarm mesh placement targets one of the primary zones of the body where heat is released. This region is rich in sweat glands and blood vessels, so integrated mesh panels here allow heat to dissipate during training of BJJ, surfing, or gym workouts. Breathable rashguards enhance yoga sessions, as they allow both flexibility and ventilation to engage your core while training.
-
Other than that, moisture-wicking fabric in these rashguards moves the sweat away from the body and the mesh across the upper back and shoulder blades to let them evaporate. Enhanced moisture evaporation is the benefit of correct panel placement. Sweat released in a mesh zone has immediate access to airflow, which means it evaporates within seconds.
-
While the fabric helps improve performance, the construction details also matter. Flatlock seams between solid fabric and open-weave panels, and reinforced double-stitched rashguards help reduce skin irritation and allow mesh panels to sit where they need to.
-
While both women’s and men’s rashguards are built differently according to their unique body shapes, both are built with strategic mesh panels to allow heat to dissipate.
Best Activities for Breathable Rashguards
Ultimate Fighting Championship fighters often wear compression rashguards during training for flexibility and sweat control. Whether you train for your BJJ competition or you need something supportive for your gym workout, a breathable mesh rashguard supports you during multiple activities, such as:
-
Rashguards for Brazilian Jiu-Jitsu (BJJ)
-
Rashguards for Surfing and Water Sports
-
Gym and Fitness Training
-
Running and Outdoor Workouts
-
Cycling and MMA Training
Common Mistakes to Avoid When Buying Breathable Rashguards
Some of the common mistakes are discussed here that you should avoid while buying a rashguard for its specialty of breathability.
-
You should not ignore the quality of fabric, as not all meshes are equal. Low-quality mesh can tear easily or lose its structure after repeated washing. So, look for premium quality rashguards that offer both strength and comfort.
-
Choosing the wrong fit can entirely change your experience. A rashguard should not be too loose, as it can compromise its compression function. If it is too tight, it can restrict your movement and breathing. So, choose a snug fit that allows a full range of motion without extra fabric.
-
Flatlock seams should be non-negotiable for athletic use, as the raised seams can create pressure points that become painful during training sessions.
-
A moisture-wicking fabric is a need more than a want. So choosing a rashguard that absorbs moisture rather than wicking it can cause major discomfort.
-
Avoid using the wrong rashguard for BJJ and MMA. Mesh rashguards are suitable for No-Gi BJJ training if the mesh panels are integrated only into the underarms and upper back. However, the full mesh rashguards are not recommended for grappling or mat sessions during BJJ or MMA training.
Final Remarks
Breathable mesh rashguards are a great choice for athletes and active individuals. They provide excellent ventilation and comfort, which helps to keep your body cool and dry during intense workouts or training sessions. The mesh panels allow for better airflow and moisture escape, which prevents overheating and improves focus. By choosing a breathable rashguard, you can enhance your performance and enjoy longer, more comfortable workout sessions. Whether you're grappling, surfing, or hitting the gym, a breathable rashguard can make a significant difference in your training experience.
FAQs
Can I use a mesh rashguard for BJJ?
Yes, mesh rashguards can be used for BJJ, but with the right construction. Rashguards with mesh limited to the underarms or upper back are good for No-Gi classes and are fully protected when worn under a Gi jacket.
How do I wash a mesh rashguard to maintain the fabric?
Use the hand washing technique or use a gentle cycle in a washing machine for 2 to 3 minutes. Use mild detergents and avoid direct heat for drying. Hang dry completely and follow the manufacturer’s instructions for proper care and maintenance.
Will a breathable rashguard still protect against UV rays?
Quality performance mesh and blended fabrics typically carry a UPF 50+ rating even in mesh zones. But this can vary according to the construction and the brand’s preference. It is best to check for the UPF rating on the product label.
Are mesh fabric and perforated fabric the same?
Perforated fabric uses laser-cut holes in solid fabric, which is not the same as mesh fabric. Perforated fabric can be more durable than mesh, but mesh fabric allows greater ventilation.
