About Us

Welcome to SisGains – an activewear brand created by women, for women. We’re here to combine performance with style and empower women to feel confident, strong, and unstoppable in their everyday lives.

Based in the Netherlands, SisGains was born out of a need for activewear that performs just as hard as you do — while still looking great. We offer a curated selection of high-quality pieces, including leggings, sports bras, shorts, crop tops, tees, joggers, sweatpants, jumpsuits, rompers, matching sets, coats, sweatshirts, and even a stylish tennis collection.

Each piece is designed to move with you — whether you’re hitting the gym, relaxing at home, or running errands. Our fabrics are breathable, durable, and ultra-comfortable, so you never have to choose between function and fashion.

But SisGains isn’t just about what you wear — it’s about how you feel. We’re here to inspire confidence, strength, and self-love. When you wear SisGains, you’re not just joining a brand — you’re joining a community of women who uplift and support each other every step of the way.

Let’s chase goals, break limits, and look good doing it — together.
