Our UPF50-certified high-performance sun protection fabric blocks over 98% of UVA and UVB rays. The long-sleeved design fully covers your arms, shoulders, and neck, making it ideal for extended outdoor water activities like snorkeling, kayaking, and SUP. It effectively reduces the risk of sunburn, allowing you to safely enjoy every moment in the sun and waves without needing to frequently reapply sunscreen.
Why do you need a long-sleeved swimsuit with genuine UPF certification?
On the water, UV rays don't just come from above; they are amplified by reflection off the water surface, causing even greater harm to your skin. Regular clothing significantly loses its sun protection when wet, but a long-sleeved UPF50 professional certified sun-protective swimsuit continuously blocks over 98% of UVA and UVB rays. Whether you're snorkeling, paddleboarding, or kayaking, it allows you to focus on enjoying your time on the water, rather than worrying about sunburn or long-term UV damage.

Four Core Advantages of NAMI PRO Long-Sleeved UPF Swimwear
UPF50 Certified Fabric for Comprehensive UV Protection
NAMI PRO long-sleeved UPF swimwear uses professionally certified UPF50 sun-protective fabric, with a long-sleeved design that fully covers the arms and shoulders. It is especially suitable for water sports that require prolonged sun exposure, such as snorkeling, kayaking, and stand-up paddleboarding (SUP). This is not just a swimsuit; it's your professional gear against UV rays.

Built-in Chest Pads for Single-Layer Convenience
The built-in lightweight chest pads provide basic support and shaping, allowing you to go directly into the water without the awkwardness of thin, see-through fabric. You no longer need to worry about wearing an additional bikini top; one sun-protective swimsuit is all you need to confidently set off, reducing the stuffiness of multiple layers and making water activities more enjoyable.

Full-Length Zipper Design for Quick On and Off, No Hair Snags
The full-length front zipper makes putting on and taking off easy and quick, especially when wet or needing a fast change, unlike traditional pull-over swimsuits that can snag hair or pull. The high-quality waterproof zipper has been tested multiple times, and an inner protective fabric strip prevents skin irritation, ensuring durability and smooth operation.

This long-sleeved swimsuit is not just a functional product; its light blue gradient texture embodies NAMI's Active Coastal style, allowing you to maintain your personal style and confidence during water activities.
