Advantages of the product

UPF50+ UV Protection

Our rash guards have professional UPF50+ sun protection performance, which can effectively block ultraviolet rays and protect the skin from sunburn during outdoor water sports such as surfing, diving and swimming, suitable for long-time outdoor use.

Our rash guards are designed with a focus on sustainability and eco-friendliness, aligning with the Global Recycled Standard and our commitment to reducing the environmental impact of water sports apparel production—without compromising on performance, durability or comfort. We offer a range of eco-friendly rash guards crafted from recycled nylon and spandex, made from post-consumer plastic bottles and textile waste that is collected, processed and spun into high-quality yarns, then woven into the same high-performance fabric used in our classic rash guards. This recycled fabric delivers the same unrivaled 4-way stretch, abrasion resistance, quick-drying performance and UPF50+ sun protection as our virgin fabric rash guards, with no compromise on quality or performance—proving that sustainable water sports apparel can be just as functional and durable as traditional options. Our eco-friendly rash guards are manufactured in our BSCI and ISO9001 certified factory, which adheres to strict environmental manufacturing protocols, including water and energy conservation, waste reduction and responsible chemical use. We implement a zero-waste cutting process in our production facility, using advanced CNC cutting machines that optimize fabric usage to minimize waste, and any excess fabric waste is recycled or repurposed for other production processes—eliminating landfill waste from our rash guard manufacturing. We use water-based inks and adhesives for all printing and finishing processes, replacing solvent-based alternatives that release harmful chemicals into the environment, and our sublimation printing process uses low-energy technology that reduces carbon emissions compared to traditional printing methods. All our eco-friendly rash guards are OEKO-TEX Standard 100 certified, ensuring they are free of harmful chemicals and safe for both the wearer and the environment, and they are fully recyclable at the end of their lifespan—closing the loop on the circular economy for water sports apparel. In addition to our eco-friendly fabric options, we design all our rash guards for longevity, using high-quality materials and durable construction techniques that extend the product’s lifespan, reducing the need for frequent replacement and further minimizing environmental impact. Our nylon/spandex fabric blend offers exceptional shape retention and tear resistance, so our rash guards do not stretch out, fade or develop holes with regular use, and the flatlock seams and reinforced stitching prevent seam failure and fraying—ensuring that our rash guards can be worn for years of water sports activities. The fabric is also easy to clean and maintain, requiring only a rinse with fresh water after use to remove chlorine, salt or sand, and it is mildew-resistant, so it can be stored without developing mold or odors—reducing the need for harsh cleaning products that can harm the environment. We offer a comprehensive range of sizes for all our rash guards, from toddler to adult plus sizes, ensuring that every user can find a properly fitting rash guard— a well-fitting rash guard is not only safer and more comfortable but also longer-lasting, as it does not experience unnecessary stretching or wear from being too tight or too loose. Our commitment to sustainability extends to our packaging and shipping processes as well; we use recycled and recyclable packaging materials for all our rash guard shipments, including cardboard boxes and paper tape, and we optimize our shipping routes to reduce carbon emissions from transportation. We also offer bulk shipping options for large orders, reducing the number of shipments and further minimizing our environmental footprint. Our eco-friendly rash guards are available in all our classic and specialized models—long sleeve, short sleeve, cropped, surfing, diving, paddle boarding and swimming—with the same customization capabilities as our traditional rash guards, including custom color matching, logo printing and pattern design. We have partnered with numerous eco-conscious water sports brands and retailers to create custom eco-friendly rash guards that align with their sustainability values, with the custom designs printed using water-based inks and sublimation printing for a vibrant, fade-resistant finish that is also environmentally friendly. For example, a sustainable beachwear brand partnered with us to create a line of eco-friendly long sleeve rash guards made from recycled nylon/spandex, featuring full-body sublimation printed ocean-inspired graphics (using low-energy sublimation printing), with UPF50+ sun protection and a performance compression fit—these rash guards have become a flagship product for the brand, appealing to eco-conscious water sports enthusiasts who want high-performance apparel that aligns with their values. A local environmental non-profit organization commissioned us to produce custom eco-friendly short sleeve rash guards for their ocean clean-up volunteers, printed with their logo via water-based screen printing, in bright high-visibility colors—these rash guards provide sun protection for volunteers during clean-up activities, and their eco-friendly construction aligns with the organization’s mission to protect the ocean. At Bestway Sports, we believe that sustainability and performance are not mutually exclusive, and our eco-friendly rash guards are a testament to our commitment to crafting high-quality, sustainable water sports apparel that protects both the wearer and the planet. Our focus on the circular economy, responsible manufacturing and product longevity makes us the ideal partner for eco-conscious brands, businesses and water sports enthusiasts worldwide.

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.

I wore this long-sleeve rash guard for snorkeling and it was perfect. It protected my back from the sun and also from rubbing against my wetsuit. The quality is excellent, feels like it will last forever.
