About Delfina Athletics

Delfina Athletics was born from the pool deck and built in the chaos of motherhood. I’m Nina Sadauskas, a three-time Olympic swimmer turned entrepreneur and mom of two boys. After retiring from the sport, I realized something was missing from the market: high-quality, thoughtfully designed swim gear that supported kids, athletes, and families in real life. So I created Delfina Athletics, a brand rooted in performance, elevated design, and lived experience. Every product is inspired by my years competing on the world stage and by the everyday moments of being a mom: goggles that don’t leak, swimwear that lasts, fabrics that move with growing bodies, and gear that makes water time easier, safer, and more joyful. What began in my living room during nap times has grown into a community-driven brand trusted by families, athletes, and team programs across the country and beyond. Our commitment is simple: Olympian-created, mom-inspired gear designed for confidence in and out of the water. We believe in quality. We believe in durability. And above all, we believe every kid deserves to feel strong, capable, and excited to dive in the water. Welcome to Delfina Athletics – premium gear designed to help swimmers of any age thrive!Read their story
