Summer Collection 2025: Bikinis & Rash Guards
Welcome to WALLIEN’s Summer Collection 2025—a curated lineup of eco-friendly bikinis and high-performance rash guards, designed to empower women in the water and protect the oceans we love. Whether you're chasing waves, exploring coral reefs, or simply basking in the sun, this collection brings you the best of both worlds: bold style and technical function.
Made from recycled Italian fabrics and natural rubber alternatives, our bikinis and rash guards are crafted to fit like a second skin, offering exceptional durability, UV protection, and movement-ready comfort. From vibrant colorways to flattering cuts, these pieces are designed by women, for water women—tested by surfers, swimmers, and outdoor athletes around the globe.
Why Choose WALLIEN’s Summer 2025 Bikinis & Rash Guards?
1. Ocean-Friendly Materials
Each piece is made using sustainable, recycled fabrics, giving new life to ocean waste like discarded fishing nets—without compromising on softness or stretch.
2. Designed for Water Women
Our bikinis feature adjustable, supportive fits, while rash guards offer UPF 50+ protection and full freedom of movement—perfect for long days in the surf or sun.
3. Stylish, Sporty, and Sustainable
From high-waisted bottoms to racerback bikini tops and streamlined long-sleeve rash guards, our Summer 2025 collection combines performance-driven cuts with summer-ready colors and prints.
4. Made to Move With You
These suits are trusted by athletes and weekend adventurers alike, thanks to their ability to stay put, dry quickly, and stand up to salt, chlorine, and UV.
Mix. Match. Move.
Create your summer set: pair your favorite bikini bottom with a color-matched rash guard or go bold with mix-and-match styles. All designs are made for active movement and confidence—whether you're surfing, snorkeling, paddleboarding or beach lounging.
