Substanz for Revoltech — CHUBBY Collection

This project explores the possibilities of LOVR™, Revoltech’s proprietary hemp-based material, developed to be fully compostable and rooted in circular design principles.

Substanz was invited to design four lines of three accessible, everyday accessories, each exploring the material through functional design, tactile qualities and long-term use. The collection, commercially available through Revoltech, comprises a cardholder, laptop sleeve and glasses case.

CHUBBY

The third line, CHUBBY, takes a more substantial and understated approach, with larger, sturdier and quieter designs created for everyday use.

The collection combines clean, minimalist forms with a focus on function and material honesty. The laptop sleeves are designed to accommodate larger laptops, while the cardholders offer additional capacity, making cards easier to insert and remove while maintaining the standard 110 mm format.

Both laptop sleeves are lined with a hemp–bamboo fleece, selected to complement the hemp origins of LOVR™ while providing a naturally soft protective layer. The glasses case is reinforced to retain its shape, while the cardholder features four functional pockets.

All accessories are designed to be fully compostable, with the sole exception of the stitching thread, which is currently composed of a 50/50 cotton–polyester blend.

Craftsmanship & Material Integrity

Each piece is hand-stitched and hand-finished, with carefully polished edges and no edge paint. Leaving the edges free from surface coatings allows the material to age naturally, highlighting the character of LOVR™ and placing craftsmanship and material integrity at the centre of the design.

The CHUBBY collection demonstrates how material selection, product development and prototyping can translate innovative biomaterials and sustainable materials into accessible everyday products. By combining hemp-based materials with considered construction and minimal surface treatment, Substanz works with material innovators to explore practical bio-based alternatives and bring circular economy solutions into real-world fashion and accessory applications.
