How to Choose Materials for a Sustainable Product Line

Choosing materials for a sustainable bag or accessory line comes down to five decisions: define the end use, match the material to that use, check what certifications back it, sample before you commit, and stay honest about each material’s limits. The brands that get this right start from the product and the application — not from whichever material sounds the most sustainable on a label.

It is an easy decision to get backwards. A material that reads beautifully in a press release can be wrong for a high-flex strap or a structured panel. This is a practical sequence our materials team uses with brands who want a lower-impact line that still survives real-world use.

1. Start with the application, not the material

Before you look at a single swatch, describe the product and where it will be stressed. A tote handle, a shoe upper, a cosmetic-bag lining and an upholstered panel all ask different things of a material — flex tolerance, abrasion resistance, structure, water behaviour. Write those requirements down first. The most common sourcing mistake is falling for a material and then trying to make the product fit it, instead of the other way around.

Once the brief is clear, you can shortlist sensibly. Our materials overview groups options by what they are best suited to, which makes that first cut faster.

2. Match the material category to the job

Broadly, sustainable material choices fall into two families. Plant-based and recycled leather alternatives suit structured goods, bags, footwear and accents where a leather-like hand is wanted. Recycled and lower-impact textiles suit linings, panels, apparel and soft goods. Knowing the family narrows the field quickly before you compare individual materials.

For a leather-like surface, compare options across our leather alternatives range — from cactus leather to cork. For soft goods and linings, the eco textiles range covers recycled and natural fibres side by side.

3. Ask what certifications actually back the claim

“Sustainable” is not a specification; certification is. For recycled content, look for the Global Recycled Standard (GRS). For organic fibre, GOTS. For substance safety, OEKO-TEX STANDARD 100. Decide which apply to your shortlist and ask whether documentation can be produced for your order — not whether the supplier “is sustainable” in general terms.

According to PwC’s 2024 Voice of the Consumer Survey, around 80% of consumers say they are willing to pay more for sustainably produced goods. That willingness only converts into trust when the claim is verifiable, which is exactly what certification provides. Our guide to GRS, GOTS and OEKO-TEX covers what each one verifies.

4. Sample before you commit — every time

No material should go into production on the strength of a photo or a data sheet. Swatches let you confirm colour, hand-feel and finish; sample yardage lets your team prototype and stress-test in the actual product. Treat physical evaluation as a required step. Minimums, colours and finishes are best confirmed per project rather than assumed from a list, so build sampling time into your development calendar from the start.

5. Respect each material’s limits

Every material has applications it is not suited to, and a sustainable one is no exception. A supplier who names those limits early is saving you money, not losing your order. Plant-based leathers, recycled textiles and natural fibres each behave differently under flex, abrasion and moisture. Plan around the boundaries rather than discovering them in production — and be wary of any material described in sweeping, unqualified terms.

Choosing sustainable materials: turn the brief into a shortlist

Run these five steps and an overwhelming field of “eco” options narrows to a handful that genuinely fit your product, your performance needs and your certification requirements. From there, the decision is made with material in hand — which is where sampling begins.
