Advantages of the product

Flatlock Chafe-Free Seams

Adopting flatlock chafe-free seam technology, the rash guard has a smooth surface, which can avoid skin friction and discomfort caused by long-time wearing and movement in the water, and improve the overall wearing comfort and experience.

Long/Short Sleeve Customizable

We support both long and short sleeve customization of rash guards, adapting to different water sports scenarios and seasonal needs. Long sleeves provide full-body sun protection, while short sleeves are more breathable and suitable for high-temperature environments, meeting diverse user needs.

Our rash guards are designed to be easy to care for and maintain, with durable materials and construction techniques that make them low-maintenance—ensuring that they remain in high-quality condition for years of water sports use with minimal effort from the wearer. Proper care and maintenance are essential for extending the lifespan of any water sports apparel, and our rash guards are engineered to simplify this process, with fabric and design features that resist damage from improper care and make cleaning and storage quick and easy. Our nylon/spandex fabric blend is inherently easy to clean, requiring only a simple rinse with fresh, cool water after each use to remove chlorine, saltwater, sand, board wax and other debris that can accumulate during water sports activities. This quick rinse is critical for preventing chlorine and saltwater from degrading the fabric over time—chlorine can cause the fabric to fade, harden and lose its stretch, while saltwater can leave a residue that can cause irritation and damage the fabric if left unwashed. A simple rinse with fresh water immediately after use removes these harmful substances, protecting the fabric and extending the life of the rash guard. For more thorough cleaning, our rash guards can be hand-washed with a mild, gentle detergent (such as a mild soap or specialized sportswear detergent) in cool water—never use harsh detergents, bleach, fabric softener or stain removers, as these can damage the fabric’s stretch, sun protection and color fastness. Hand-washing is the preferred cleaning method for our rash guards, as it is gentle on the fabric and flatlock seams, but they can also be machine-washed on a gentle, cold water cycle in a mesh laundry bag to protect the fabric and prevent snags on other clothing items. Our rash guards should never be dry-cleaned, as the dry-cleaning chemicals can damage the nylon/spandex fabric and the sun protection treatment. After cleaning, our rash guards should be air-dried in a cool, shaded area—never tumble dry, iron or dry clean them, and never hang them in direct sunlight to dry. Tumble drying and ironing can damage the fabric’s elasticity and sun protection treatment, and direct sunlight can cause the fabric to fade over time. Air-drying in a shaded area ensures that the rash guard dries quickly and gently, preserving its stretch, color and sun protection performance. Our rash guards are also mildew-resistant, so they can be stored in damp areas (such as beach bags, pool lockers or boat storage compartments) for short periods of time without developing mold or odors—however, it is always best to store them in a cool, dry, well-ventilated area after they are completely dry to prevent any potential mildew growth. For long-term storage, our rash guards should be folded neatly and stored in a dry place, away from direct sunlight and sharp objects that can snag or tear the fabric. Our rash guards are designed to resist stretching out of shape with proper care, thanks to the high-quality nylon/spandex fabric blend that offers exceptional shape retention—however, it is important to avoid overstretching the rash guard when putting it on or taking it off, and to avoid hanging it on a hanger for long periods of time (which can cause the shoulder seams to stretch). Folding the rash guard for storage is the best way to preserve its shape and fit. We provide clear, easy-to-follow care and maintenance instructions with all our rash guard orders, both in digital and hard copy formats, so our clients and their customers know exactly how to care for their rash guards to extend their lifespan. For commercial clients such as surf schools, water parks and swim schools, we also provide customized care instructions for their staff, to ensure that the rash guards are properly cleaned and maintained between uses—this is critical for commercial use, where rash guards are worn by multiple users and need to be kept clean and in good condition for daily use. Our easy-care design features have made our rash guards a popular choice for both recreational and commercial users, who value the low-maintenance nature of the product—no more spending hours cleaning and caring for water sports apparel, just a quick rinse and air dry, and the rash guard is ready for the next use. For example, surfers who use our rash guards daily for open-ocean surfing appreciate the easy care—they simply rinse the rash guard with fresh water after each surf session, hang it to dry in the shade, and it’s ready for the next day’s surf. Swim schools that use our kids rash guards for daily lessons value the easy cleaning—staff can quickly rinse the rash guards with fresh water after each lesson, sanitize them with a mild disinfectant (for commercial use) and air dry them for the next group of students. At Bestway Sports, our focus on easy care and maintenance is a reflection of our commitment to crafting practical, user-friendly water sports apparel that meets the needs of real-world water sports enthusiasts and commercial users. Our high-quality, durable materials and easy-care design features ensure that our rash guards provide years of reliable performance with minimal maintenance—making them a smart investment for anyone who loves water sports.

This men's rash guard is perfect for surfing. It's comfortable, dries quickly, and the UPF 50 protection is no joke – no sunburn after a long day in the water. The flatlock seams are comfortable and don't chafe.

I love the cropped UPF 50 rash guard for women. It's so stylish and perfect for wearing with high-waisted swim bottoms. The fabric is high quality and the sublimation print is vibrant. Great for surfing and beach volleyball.
