How RainyDays Was Founded: A Belgian Brand for Female Climbers
Share
Climbing isn’t just a sport — it’s a mindset. When founder Karlijn Eggers looked for climbing apparel that truly fit the female body, she noticed a gap: most clothing available was either scaled‑down men’s designs or lacked the freedom of movement, comfort, and functional fit women need. That realization became the foundation of RainyDays Sportswear — a brand rooted in Belgium and built for women who move, climb, train, and live actively.
The Story Behind the Name
The name RainyDays goes beyond literal rainy weather. It captures the idea of finding strength and motivation on days that feel low, gray, or challenging — the days when your energy dips but your determination doesn’t. Whether it’s going for a walk, a hike, a yoga or Pilates session, a run, or heading to the climbing gym, RainyDays celebrates the resilience to get outside and stay active, no matter how the day feels. Just as rain doesn’t stop a dedicated climber, RainyDays inspires women to move, improve, and reach new heights.

Core Values That Define RainyDays
From the start, RainyDays has been built on a clear set of principles:
- Designed with women in mind: Every piece is shaped around the female form to ensure fit, comfort, and confidence.
- Freedom of movement: Technical fabrics with four‑way stretch let you move naturally — whether clipping bolts or flowing through a yoga sequence.
- Thoughtful design and care: Each garment is crafted with attention to detail, reflecting our commitment to function, style, and the needs of active women.
-
A true active lifestyle focus: While climbing is at the heart of who we are, our apparel also supports women in yoga, Pilates, walking, running and everyday movement.

From Idea to Reality
Karlijn began RainyDays with the mission to combine performance, comfort and real‑life versatility in every garment. Early designs were tested not just in climbing gyms, but in real movement situations — from climbs and hikes to yoga classes and morning runs — ensuring each piece matched the needs of active women across disciplines.
Why RainyDays Is Different
RainyDays stands out because it was born from experience, not trend reports. Many activewear brands generalize; RainyDays specializes. We focus on how clothing feels in motion — from belays and boulders to downward dog and trail runs — and how it supports a woman’s body through each of those moments.
Our collections are carefully designed to be more than just functional — they’re comfortable, flattering, and versatile. Whether you’re crushing at the gym, stretching into pose, or exploring trails on a weekend, RainyDays gear moves with you.
Looking Ahead
Today, RainyDays continues to grow while staying true to our original vision: a women’s active apparel brand rooted in climbing, built for movement, and designed for real life. We believe in creating clothes that help women feel confident, free, and motivated to pursue the activities they love.
