Sustainable Custom Merchandise: A Guide for Brands and Bands

Custom merchandise is one of the most tangible expressions of a brand. A t-shirt worn on tour, a hoodie handed out at a launch, a tote given at a festival, all of them travel further than most campaigns. Sustainability decisions made on those pieces travel just as far. This guide covers the choices that actually matter when producing eco-friendly branded apparel and merchandise: certifications, materials, decoration techniques, and packaging.

Why sustainable merchandise matters

Apparel is one of the most resource-intensive product categories on the planet. A single conventional cotton t-shirt can require more than 2,700 litres of water, plus pesticides and long chemical finishing chains. Multiply that by a tour run of 5,000 pieces or a full onboarding kit for a growing company, and the footprint is real. Choosing sustainable custom merchandise is not a marketing add-on: it is where a brand's operational values become visible.

The certifications that carry weight

Two labels do most of the work in this category. GOTS (Global Organic Textile Standard) covers the entire textile chain, from organic fibre to social conditions in the workshop that produces and prints the garment. OEKO-TEX Standard 100 certifies that a finished product contains no substances harmful to human health.

A GOTS-certified workshop is a strong signal because the audit includes the printing stage itself, water use, chemical management, and worker conditions. Big Frenchy operates a GOTS-certified workshop in Chelles, near Paris, and works with OEKO-TEX Standard 100 blanks across the catalogue.

Materials to prioritise

The clearest wins come from switching the base garment before you think about the print.

• Certified organic cotton. Grown without synthetic pesticides. Look for GOTS on the blank, not just on the workshop.
• Recycled cotton and recycled polyester. Uses fibre already in circulation. A high recycled-content blend cuts water and energy use substantially versus virgin cotton or virgin polyester.
• Responsibly sourced wool and linen. Lower-impact natural fibres for outerwear, headwear, and workwear.
• Recycled or recyclable accessories. Tote bags in recycled cotton, drinkware in recycled stainless steel or glass, notebooks with FSC-certified paper.

Around 80% of the products Big Frenchy sources for eco-focused projects are recycled or recyclable, without compromising on hand feel or print quality.

Choosing a low-impact printing technique

The decoration method matters almost as much as the garment.

• Water-based screen printing. Traditional plastisol inks are PVC-based. Water-based inks penetrate the fibre for a softer hand and a lower-impact chemical profile. Best for larger runs and bold artwork.
• DTG on Kornit Atlas. Kornit's Atlas system uses NeoPigment inks that are OEKO-TEX ECO PASSPORT certified, with near-zero wastewater at the print stage. Ideal for photographic artwork and small to medium runs without setup waste.
• Embroidery. No inks or coatings. Longest-lasting decoration on hoodies, caps, and workwear.

Techniques to think twice about for eco-first briefs: solvent-based transfers, PVC-heavy vinyl, and full-coverage sublimation on non-recycled polyester.

Packaging and finishing

Packaging often undoes the good work done on the garment. A few practical swaps:

• Recycled or compostable polybags in place of virgin LDPE.
• Recycled cardboard mailers with paper tape.
• Hangtags in recycled or FSC paper, printed with vegetable inks.
• Woven labels in recycled polyester, or printed labels directly on the garment to remove the tag entirely.

Building a sustainable brand through merchandise

The pieces that make it into rotation, the tour hoodie, the office fleece, the festival tote, are the ones that quietly define how a brand is remembered. Sustainable choices at that stage do more than reduce a footprint: they make the merchandise itself something people want to keep, wear, and reuse. That is the actual measure of a successful eco-friendly branded apparel program.
