Byci Key Features

1 – Biodegradable Fabric

Developed in Brazil in partnership with Rhodia® (Solvay® Group), (CO₂)® fabric is the world’s first biodegradable nylon. It decomposes in approximately three years in landfills, while traditional nylon takes decades. A pioneering technology that drastically reduces environmental impact and combats microplastic pollution.

2 – Structured Fabric (222 g/m²)

Structured fabric with 222 g/m² of weight, providing greater support, a sophisticated touch, and zero transparency.

3 – UV Protection 80+ Fabric

BYCI pieces offer high-performance sun protection, tested under ARPANSA and Stretch + Wet® protocols. Even when stretched or wet, the fabric maintains an 80+ UV protection factor, ideal for those seeking maximum sun safety.

4 – Double-Layer Fabric

The double-layer construction ensures firmness, comfort, and full coverage, eliminating the need for additional linings. This structure provides a perfect fit to the body and a soft, refined feel on the skin.

5 – Concealed Seams

Each piece is carefully finished with concealed seams, eliminating visible marks and delivering a clean, elegant, and comfortable finish — a detail that reflects premium fashion standards.

6 – Elastic Along the Entire Edge

Reinforced elastic runs throughout the piece, offering anatomical support and freedom of movement without tightening or distorting the fabric.

7 – Heat-Transfer Label

Our labels are heat-applied — no stitching — to avoid skin irritation and maintain a clean and refined interior finish.

8 – Full-Coverage Fit

Designed to flatter all body types with elegance, BYCI’s fit provides greater coverage, support, and comfort.

9 – Timeless Design

Each creation is made to last. Clean lines and minimalist aesthetics make our pieces timeless — designed to transcend seasons and remain relevant over the years.

10 – Versatile Style
