B-THREE's Eco Campaign Reaches 4.8 Million Garments Collected – Celebrating 18 Years of Social Contribution

B-THREE, a specialist stretch pants brand operated by Value Planning Co., Ltd., will launch its clothing collection initiative 'Eco Campaign' on June 15, 2026, at 137 stores nationwide and on its official e-commerce site.

This campaign has been ongoing since 2009 and marks its 18th year and 33rd iteration.

To date, approximately 4.8 million items have been collected, with around 1.12 million customers participating, contributing to waste reduction.

This year, B-THREE will also simultaneously launch the 'Koe Campaign,' reflecting customer feedback such as 'I just want cooler pants!' into product planning. Through clothing circulation and customer-driven development, B-THREE aims to realize sustainable fashion.

About the B-THREE Eco Campaign, launched in 2009

What is the 'B-THREE Eco Campaign'?

In recent years, the mass production and disposal of clothing have become social issues.

B-THREE operates under the philosophy of 'wearing good things for longer and with care.' Beyond selling products, the company continues initiatives that include collecting and reusing clothing that has served its purpose.

Clothing collected at stores nationwide is either reused or recycled depending on its condition.

Wearable clothing is donated or reused, while items unsuitable for reuse are transformed into new resources such as automotive interior materials or recycled polyester through fiber recycling.

Collection targets are not limited to B-THREE products; items from other brands, including women's, men's, and children's wear, are also accepted, and anyone can participate.

Additionally, B-THREE's social contribution activities, including the Eco Campaign, have been recognized with the 'Social Contribution Award' at the 28th Tenant Grand Prix selected by developers, hosted by Senken Shimbun.

'Wear good things longer and with care' – Our commitment to eco-friendly pants

Our unique philosophy: 'Anti-Apparel Apparel'

Most apparel brands focus on transient 'design' based on changing trends and personal preferences. In contrast, we have consistently prioritized 'quality' to create products meant to be cherished and worn for years.

Rather than chasing trends, we encourage customers to wear what fits them best for as long as possible.

We call this philosophy 'Anti-Apparel Apparel' and uphold it as the foundation of our product development.

Our dedication to unique materials and silhouettes, cultivated over 32 years of research

While most apparel brands purchase fabrics from textile manufacturers, we develop our own yarns from the very beginning.

Our proprietary stretch fabric, which stretches and recovers well, delivers not only comfort but also high durability and quality. The unique 'Golden Leg Ratio,' developed over 32 years of research, creates a flattering silhouette. We create timeless pants that appeal to everyone, regardless of age, trend, or personal taste.

The 'Beautiful Leg Lab' – Researching and developing eco-friendly pants

B-THREE has established the 'Beautiful Leg Lab' to research and develop pants designed to be worn for years.

The lab conducts over 60 quality tests to evaluate texture, stretch, and durability.

For example, a verification robot named 'Kusshin-chan,' which performs about 100,000 bending motions per day, is used to ensure no quality degradation such as knee bagging occurs.
