A Long Sleeve Swimsuit That Stays Secure and Sculpts Beautifully.
This is the one that started it all. The Sulawesi Nautical - our original and most-loved long sleeve swimsuit, worn season after season.
Designed for real water, it sculpts, supports and stays in place through surf, swimming and ocean movement - so you feel held, secure and free to move.
The crisp white waistband defines the waist, navy panels contour the body, and striped sleeves create a signature contrast that feels both flattering and timeless.
Designed as UPF 50+ long sleeve swimsuit for women, with full coverage from shoulder to wrist - so the rash guard stays in the bag.
Crafted from premium Italian ECONYL®, a regenerated nylon used in sustainable swimwear, it feels smooth against the skin while maintaining shape, colour and compression over time.
✔ 12 Month Quality Guarantee
✔ Easy Returns & Exchanges
✔ Sustainably and Ethically produced
