A custom rashguard is more than just a stylish swim shirt—it’s designed to provide UV protection, reduce irritation, and improve mobility for water sports. Whether you’re surfing, diving, or swimming, the right rashguard enhances both safety and performance. However, many people overlook key details when customizing their rashguards, leading to poor comfort and limited protection.
In this article, we’ll explore the most common mistakes in custom rashguard designs and how you can avoid them for the best results.
1. Choosing Fashion Over Function
One of the biggest errors is focusing only on the look. While unique prints and logos are important, function should always come first. A good rashguard must offer stretch, quick-dry ability, and UPF sun protection—otherwise, you’ll sacrifice safety for style.
2. Ignoring the Right Fabric Blend
Fabric quality makes a huge difference. Some custom rashguards are made with low-grade polyester, which feels heavy and loses elasticity. The best materials combine polyester and spandex for flexibility, durability, and comfort in both saltwater and chlorine pools.
3. Incorrect Fit and Measurements
Custom wear should fit like a second skin, but not restrict movement. Oversized rashguards create drag in the water, while overly tight fits can cause discomfort. Always double-check size charts and provide accurate measurements before ordering.
4. Forgetting About Sleeve Options
Not all activities require the same style. Long-sleeve designs offer full UV protection, while short-sleeve or sleeveless rashguards may work for casual swimmers. Picking the wrong sleeve length can reduce performance or leave skin unprotected.
5. Overlooking UPF Rating
A stylish design is useless if it lacks sun protection. Look for UPF 50+ as the standard. Some custom rashguards skip this feature, exposing you to harmful UV rays during long sessions outdoors. A high UPF rating should be a priority.
6. Poor Stitching & Seams
Durability matters when you’re active in the water. Flatlock stitching is the best choice for rashguards, as it reduces chafing and ensures strength. Weak seams not only irritate the skin but also shorten the garment’s lifespan.
7. Not Considering Printing Method
The way your design is printed also matters. Cheap printing fades quickly after sun and saltwater exposure. Sublimation printing is the most reliable option for custom rashguards, as it keeps colors vibrant and designs long-lasting.
8. Ignoring Care Instructions
Even the best custom rashguard won’t last if not maintained properly. Always rinse after swimming, avoid hot dryers, and let it air-dry in shade. This keeps elasticity strong and prevents fading.
Conclusion
A custom rashguard is an investment in both style and function, but it only works if designed correctly. By avoiding mistakes such as poor fabric choice, weak stitching, or ignoring UPF ratings, you’ll ensure comfort and long-term performance. Choosing the right custom rashguard means you can focus on your sport while staying protected and looking your best.
