ATENA Launches Bamboo-Based Absorbent Underwear: Releasing 'Girl's Wish' with Uncompromising Craftsmanship on May 28

ATENA (Headquarters: Hino, Tokyo) has begun sales of its independently developed absorbent underwear.

Inspired by a girl who once said, 'I can't sleep unless I put a towel on my bed,' engineers realized the 'invisible constraints' women unknowingly face. The desire to help women concentrate on their passions and live beautifully drove this development.

Developed after testing over 40 materials, this product combines bamboo rayon, a unique 4-layer structure, and a PFAS-free leak-proof design to support women in their daily lives, whether studying or working.

Development Background:
We refuse to compromise on functionality. We selected bamboo rayon and fine-tuned the waterproof layer at 0.1mm intervals to create a structure that offers both softness and strength. For us, true luxury is time undistracted. It took a full year to perfect the 4-layer structure, a testament to our commitment to quality.

Three Key Features:
1. Unique 4-Layer Structure: Each layer plays a specific role (contact layer, absorption, leak-proof barrier, outer layer).
- Absorption Capacity: Approx. 10mL (light days), Approx. 30mL (moderate to heavy days).
2. PFAS-Free Leak-Proof Design: Prioritizing safety, especially for products directly touching the skin.
3. Smooth Texture of Bamboo Fiber: Bamboo rayon blended with cotton provides a silk-like feel, offering comfort even during long hours of wear. As bamboo is a renewable resource, this product also contributes to reducing waste.
