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.

Multi-Functional Fabric

The rash guard is made of high-quality nylon/spandex blended fabric, which has quick-drying, breathable, 4-way stretch and abrasion-resistant properties. It dries quickly after being wet, has good elasticity, and can withstand the friction of water sports equipment and water flow.

Our rash guards offer unparalleled customization capabilities, a core strength of our business as a leading 17+ year OEM/ODM manufacturer of water sports apparel, with the ability to create fully bespoke rash guards that align perfectly with the brand identity, design vision and functional needs of every client—from global water sports brands to local surf schools, swim clubs and retail businesses. Our customization process is client-focused and streamlined, with a professional design team that works closely with every client to understand their unique requirements and translate their vision into a high-performance, durable rash guard that meets the highest quality and performance standards. We offer a comprehensive range of customization options for our rash guards, covering every aspect of the product from fabric and fit to color, logo and pattern design, ensuring that clients can create a truly unique product that stands out in the competitive water sports market. Our fabric customization options include choosing from our classic nylon/spandex blends (80/20, 85/15, 90/10) for different performance levels (abrasion resistance, flexibility, lightweight comfort), our eco-friendly recycled nylon/spandex blend for sustainability-focused clients, and our hybrid neoprene/nylon blend for cold-water and performance-focused water sports such as surfing and diving. We can also adjust the fabric weight and thickness to meet specific client needs—from ultra-lightweight for swimming and casual water play to heavy-duty for surfing and diving. Our fit customization options include creating custom size ranges (for specific regions or demographics), adjusting the silhouette (cropped, classic, relaxed, compression), modifying the neckline (crew, scoop, mock) and sleeve length (long, short, cap) and even adjusting the hem and cuffs for a custom fit. For brand partners targeting specific water sports audiences, we can tailor the fit to the unique needs of the activity—for example, a tighter compression fit for surfers, a looser fit for divers and a relaxed fit for paddle boarders. Our color customization options are extensive, with over 200 stocked fabric colors available for immediate production, as well as full Pantone color matching for clients who need exact brand color reproduction—we can match any Pantone color with precision, ensuring that the rash guard aligns perfectly with a brand’s visual identity. We offer solid color options, two-tone color blocking and gradient colors, all created with high-quality fabric dyes that are fade-resistant and resistant to chlorine and saltwater degradation—ensuring that the color remains vibrant and true for the life of the rash guard. Our logo and pattern customization options are the most comprehensive in the industry, with three professional printing technologies available to meet different design needs: screen printing, sublimation printing and heat transfer printing. Screen printing is ideal for simple logos, text and small graphics, offering a durable, cost-effective solution for large bulk orders, and we use water-based inks for screen printing to ensure environmental friendliness and skin safety. Heat transfer printing is perfect for detailed logos, small graphics and brand tags, offering high precision and a smooth, soft finish that does not affect the fabric’s stretch and flexibility. Sublimation printing is our premium printing option, allowing for full-body, high-resolution pattern designs—from intricate surf graphics and ocean-inspired prints to brand-specific patterns and custom artwork—with vibrant, fade-resistant colors that become an inherent part of the fabric (not a topical coating), so the print does not crack, peel or fade with wear, washing or exposure to chlorine and saltwater. Sublimation printing is ideal for brand partners looking to create eye-catching, unique rash guards that stand out in the market, and our design team can create custom sublimation patterns from client artwork or original designs. We provide free design services for all custom logo orders with an MOQ of 50, including logo placement optimization, color matching and design adjustments to ensure that the logo looks perfect on the rash guard. For clients who need original pattern designs, our professional design team—with extensive expertise in water sports fashion and performance—can create custom artwork and patterns that align with the brand’s identity and target audience, from fun, kid-friendly graphics for family brands to sleek, modern designs for professional water sports brands. We offer fast sampling for all custom orders, with a streamlined sample production process that delivers high-quality prototypes in a short timeframe—our samples are production-quality, allowing clients to test the fit, fabric, color and print quality before bulk production begins, and we offer unlimited design adjustments to ensure that the client is completely satisfied with the sample. Our advanced production equipment and skilled technical team ensure that all custom rash guards are produced with precision and consistency, even for large bulk orders, and our strict quality control protocols ensure that every unit meets the client’s exact specifications and the highest international quality standards. Our customization capabilities have made us the preferred OEM/ODM partner for numerous global and local water sports brands, surf schools, swim clubs and retail businesses. For example, a luxury water sports brand partnered with us to create a line of custom cropped women’s rash guards in their signature Pantone color, with a small, subtle logo printed via heat transfer printing on the chest, crafted from a soft, lightweight 90/10 nylon/spandex blend—these rash guards have become a staple in the brand’s beachwear collection, with customers praising their stylish design and high-performance fabric. A local surf school commissioned us to produce custom long sleeve surfing rash guards in bright orange (a high-visibility color), with the school’s logo printed via screen printing on the back, crafted from a heavy-duty 80/20 nylon/spandex blend with a performance compression fit—these rash guards are used by the school’s students for daily surf lessons, and their durable construction and high-visibility color have made them a favorite among instructors and parents. At Bestway Sports, our unparalleled customization capabilities, combined with our 17+ years of rash guard manufacturing experience, international certifications and advanced production equipment, make us the leading OEM/ODM partner for custom rash guards in the global water sports industry. We are dedicated to turning our clients’ design visions into high-performance, durable and stylish rash guards that meet their exact needs and exceed their expectations.

David Brown

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.

Noah

My boys are rough on their clothes, but these kids' rash guards are holding up great. The long sleeves provide excellent sun protection, and the fabric is stretchy so they can move freely. We bought multiple.
