Two routes to a recycled swimsuit
Recycled swimwear virtually always means one of two materials: rPET, made from post-consumer plastic bottles, or regenerated nylon from discarded fishing nets and textile waste. Both carry a credible environmental story, but they are not interchangeable in performance.
| Material | Source | Strengths | Watch-outs |
|---|---|---|---|
| rPET | Post-consumer plastic bottles | Cost-effective, widely available, strong chlorine resistance | Slightly firmer hand feel |
| Regenerated nylon | Fishing nets and textile waste | Softer hand feel, excellent stretch recovery | Higher cost and longer lead time |
Chlorine resistance is the deciding factor for many buyers
If your customers swim in pools, chlorine resistance matters more than the recycled content story. Chlorine degrades elastane over time, which is why cheap swimwear sags and loses shape within a season. Confirm that the fabric has been tested against pool chemistry rather than assuming that any stretch fabric will hold up.
Documentation before you make a claim
Recycled-content marketing claims are regulated in most major markets, and regulators increasingly ask for evidence. Before printing eco messaging on a hangtag, obtain documentation covering the recycled content percentage and the chain of custody from the fibre source through to the finished fabric.
Never make a percentage claim such as “made from 78% recycled materials” without documentation that specifically supports that figure for the fabric you bought.
Cost expectations
Recycled fabric typically carries a modest premium over virgin equivalents, though the gap has narrowed as supply has matured. For a mid-tier swimwear range, the premium is usually absorbed without pushing the retail price out of the market, which is why recycled swim has moved from a niche line to a standard option.
